INTRODUCTION
1 PURPOSE AND SCOPE.
This technical order (TO) describes the procedures and techniques employed to assign TO numbers to technical data used to
operate, install, maintain, inspect, perform procedural functions on, and modify Air Force weapons systems and equipment.
Numbering techniques are not included in this TO for TO numbering assignments made according to waivers or deviations
from established procedures.
1.1 Alphabetical Listing. Chapter 42 of this TO provides an alphabetical listing of equipment names cross-referenced to
appropriate TO number groups as they appear in the Air Force TO Catalog. Basic names of equipment systems and
components are in all caps. Variations or breakdowns of the equipment follow in small print. This listing does not indicate
the status of individual publications. The only authorized sources for determining the status and availability of individual
publications are the Enhanced Technical Information Management System (ETIMS) and the Air Force catalog which is
available through the AF Portal.
2 REFERENCES.
Referenced publications, forms, acronyms and definitions are located in Appendix A. The directives identified in Appendix A
provide policy, guidance and references used to make TO number assignments to approved TO data.

CHAPTER 1
GENERAL INFORMATION
1.1 GENERAL.
TOs are procured from contractors or prepared in-house by Air Force activities. The Program Manager (PM) responsible for
a weapon system or commodity is also responsible for TOs to support that system or item. PMs will assign TO Managers to
carry out this responsibility. Only the responsible TO Manager is authorized to request TO number assignment. Only
AFLCMC/LZPT-Tinker is authorized to approve and assign TO numbers for most TOs. Exceptions include nuclear weapons
(NW) TOs (assigned by the Naval Surface Warfare Center Indian Head EOD Technology Division [NSWC IHEODTD]),
Explosive Ordnance Disposal (EOD) TOs (assigned by Naval EOD Technology Division (NAVEODTECHDIV)); and cat-
egory 33K Calibration TOs (assigned by DoD Joining Technical Coordination Group for Calibration and Measurement
Technology (JTCG-CMT), Air Force Metrology and Calibration [AFMETCAL]). Publications not authorized by TO 00-5-1,
AF Technical Order System , will not be numbered in the TO system without prior approval by AFMC/A4FI, after coordi-
nation with AFLCMC/LZPTP-Tinker.
1.1.1 TO Number Request. TO Managers complete the Request TO Number screen in ETIMS for each formal or
preliminary TO (PTO), and submit them to AFLCMC/LZPT-Tinker for TO number approval. Contractors and TO Managers
not on-line with ETIMS may continue to use the AFTO Forms 203, TO Numbering, Indexing and Control Record.
NOTE
When a new TO number is requested, the TO Manager or Equipment Specialist (ES)/Technical Content Manager
(TCM) must submit a HDRC ticket to add the Federal Stock Class (FSC), part number(s) and Commercial and
Government Entity (CAGE) code of the equipment listed in the TO title into ETIMS. For TOs against components
or support equipment peculiar to a weapon system, also enter the weapon system Mission/Design/Series (MDS).
1.1.2 Mil-Std. Most TOs are prepared according to military standards and performance or detail specifications which
prescribe the contents of each TO type. This standardized approach facilitates the uniform assignment of descriptive TO
numbers. However, there is increased emphasis on purchasing Commercial Off-The-Shelf (COTS) manuals. The lack of a
standard format between COTS manuals complicates the grouping of like data into established TO numbering patterns. To
maintain stability in the numbering system, AFLCMC/LZPT-Tinker and AFMC/A4FI provide guidance for TO Managers
and develop, coordinate and implement new numbering patterns as required.
1.1.3 TO Assigned Groups. Numbers are assigned to group TOs according to the systems and equipment they cover (
Paragraph 1.3.2), to provide sequences for filing and indexing, and furnish a means for users to identify and establish
requirements for distribution of TOs. The structure of the TO number identifies a category of Air Force systems or com-
modities, a design or series of equipment within a system or commodity category, an equipment sub-series within an
equipment series, the type of data included in the TO, and the medium on which the TO is distributed.
1.1.4 Multiple TO Numbers on One Media. Numbers are assigned on a system or end item MDS basis whenever
possible. TOs containing instructions or procedures applicable to more than one major group are numbered in a general
series for the particular category. If multiple TOs are included on a single distribution medium (e.g., Compact Disc-Read
Only Memory [CD-ROM] or Digital Versatile Disk), a single unique number will be assigned to the medium ( Paragraph
1.23).
1.1.5 TO Categories. TO categories are not numbered in a consecutive sequence. Currently, 42 categories are identified
between Category 0 and Category 60 ( Paragraph 1.3.2). Category 0 is assigned to the TO catalog and cross-reference table
TOs. Category 00 is assigned to Methods and Procedures TOs (MPTOs). Categories 1 through 22 are assigned to airborne
systems for aircraft, missiles, aerospace vehicles, and related airborne equipment and component assemblies. Exceptions are
the photographic equipment in category 10 and the armament equipment in category 11. Categories 31 through 51 are
assigned to Air Force ground systems and related equipment. Category 60 is assigned to EOD TOs.
TO 00-5-18

1.1.6 SATOP. The number 71 is reserved for indexes applicable to the Security Assistance TO Program (SATOP); e.g.,
TO 0-1-71 is the index listing ″M″ - symbol (″Rescinded for AF, Retained for SAP″) and ″XX″ (authorized to multiple
countries) Country Standard TOs (CSTOs). Other Country-specific SATOP indexes are numbered using the two-letter coun-
try symbol as a prefix.
1.1.7 TO Catalog. The Air Force TO Catalog Application lists current TOs, changes since the last publication of the
Catalog and a cross- reference to equipment numbers. It includes all active TOs in Categories 0 through 51. The ″XX″
version of the Air Force TO Catalog is provided for FMS/SAP customers at AFSAC on line.
1.1.7.1 The Air Force Civil Engineer Center, EOD Joint Service Acquisition, Sustainment and Technology Division
(AFCEC/CXE), is the AF EOD liaison office to the NSWC IHEODTD, Indian Head, MD. NSWC IHEODTD numbers
Nonnuclear EOD (Category 60) TOs and are indexed as part of the Joint Service EOD Mobile Field Kit, Automatic EOD
Publications System (AEODPS) software, published quarterly.
1.1.7.2 The FMS TO System Section, AFLCMC/LZPT-Tinker, Tinker AFB, OK, manages the Security Assistance TO
Data System (SATODS), which provides several special Category 71 indexes that list CSTOs used only by specific FMS/
SAP countries.
1.1.8 TO Number Verification. A close working relationship is needed between TO numbering specialists in AFLCMC/
LZPT-Tinker and TO managers to avoid inaccurate TO number assignments. Numbering specialists must verify and approve
TO numbers requested by TO managers, using information provided in ETIMS entry screens or on AFTO Forms 203. If the
information is misleading, insufficient, or in error, the numbering specialists could approve an incorrect TO number. This
error could have adverse effects on anyone attempting to identify and obtain TOs to support operations and maintenance.
One major impact of an incorrect TO number assignment is the sizeable funds expenditure required to correct the number,
especially when not only must the TO involved be renumbered, but other technical data that contains cross-references to the
incorrect TO number must be changed as well.
1.1.9 TO Numbering Information. In addition to correctly completing ETIMS screens and AFTO Forms 203, TO man-
agers provide assistance to numbering specialists by suggesting TO numbers, identifying categories and equipment, and
furnishing telephone and written communications that aid in categorizing specific TO data. It is important that the Equipment
Specialists (ES) or Item Manager (IM) provide accurate data to the TO manager so that the TO numbering specialists has all
the information necessary to assign a correct TO number. Close attention should be paid to the TO title. TO titles must be
formatted according to Appendix B, Developing TO Titles.
1.2 ENHANCED TECHNICAL INFORMATION MANAGEMENT SYSTEM (ETIMS).
ETIMS is the Air Force TO management system of record. It is currently deployed Air Force wide. It is used by TO
Distribution Office (TODO) accounts for TO ordering, account management, and digital TO distribution. It is also used by
TO Managers for all TO number requests, indexing, modification of TO meta data, TO distribution and all TO releated
matters. Legacy paper TOs are printed and distributed by the Defense Logistics Agency (DLA) & Document Services TO
Distribute & Print Service (TODPS).
1.3 TECHNICAL ORDER NUMBERING THEORY.
1.3.1 TO Grouping. The basic task of TO numbering specialists is to group similar TO data into categories, systems,
equipment series and equipment sub-series by means of an identifying numeric or alpha-numeric TO number. The following
special characters are not allowed in the TO number when uploading eTOs for deployment:
• ^, \, ’, #, $, %, *, &, +, ?, <, >,/,|, “,:
These characters prevent the uploaded files from deploying properly to the ETIMS repository. TOs and TCTO headers
with these characters will not be approved.
1.3.1.1 Existing eTOs, with no matching paper TO, currently indexed with special characters not allowed, will be renum-
bered, removed, and redeployed.
1.3.1.2 When there is a paper TO version of the eTO, remove the not allowed special character from the WA-1 TO number
so the eTO can deploy and perform the renumbering action on the paper TO at the next change of the TO.

1.3.3 TO Numbering Patterns. Each category of TO data has its own TO numbering pattern. Sufficient flexibility exists
within the total numbering system to allow for expansion or contraction within numbering parameters, yet maintain standard
application of numbering patterns within each category.
TO 00-5-18
1-3
1.3.4 TO Number Groups vs Parts. TO numbers are composed of groups separated by dashes, and each group is further
divided into parts. The number of parts within any group varies according to the TO data being numbered in a specific
category. Each part of a group consists of one or more numeric characters or one or more alpha characters. The numbering
patterns used to identify TO data in each category are outlined in Chapters 2 through 41.
1.3.5 TO Numbering Groups. A total of seven groups may be used in the TO numbering pattern (see Table 1-1). TO data
is identified, in most categories, by using only the first three or four basic groups. The remaining groups are primarily used
to extend the TO number to identify specific sections of sectionalized TOs; supplemental manuals; and supplement, checklist
and work-card sequence numbers.

1.3.6 TO Numbering Major Elelments. The five major elements of information considered most essential in assigning
TO numbers are discussed below:
1.3.6.1 Federal Supply Class (FSC). An FSC is assigned to Air Force stocklisted equipment by cataloging specialists. A
system or equipment item that has not been assigned an FSC is non-stocklisted, and a TO number will not be assigned to the
related technical data. The FSC identifies a system, sub-system, and equipment series that can be related to a TO category
and equipment series. The FSC is the first four digits of the NSN. EXAMPLES:
1.3.6.1.1 FSC 5825 identifies ground radio navigation equipment and relates to TO numbering as follows:
31R4
31 Ground Electronic Equipment (Category 31)
R Radio System
4 Navigation Equipment Series
1.3.6.1.2 FSC 5826 identifies airborne radio navigation equipment and is related to TO numbering as follows:
12R5
12 Airborne Electronic Equipment (Category 12)
R Radio System
5 Navigation Equipment Series
1.3.6.2 Descriptive Nomenclature. The nomenclature provided on the ETIMS Screens or AFTO Forms 203 supplements
the FSC by further defining the system or equipment series. A combination of only the FSC and the descriptive nomenclature
can, in many instances, provide the numbering specialist with a complete TO number. For example, if FSC 5826, airborne
radio navigation equipment, is provided in conjunction with an equipment nomenclature reading ″Maintenance Manual --
Radio Set, Type AN/ARN-24,″ the following TO number may be assigned:
12R5-2ARN24-2
12 Airborne Electronic Equipment (Category 12)
R Radio system
TO 00-5-18
1-4
5 Navigation Equipment Series
2 Numeric 2 indicates the Equipment has a JETDS nomenclature ( Paragraph 1.19)
ARN JETDS Nomenclature that indicates: A - Airborne; R - Radio; N - Navigation
24 Radio Model 24
2 Maintenance Manual
1.3.6.3 Functional System. The functional system furnished on the ETIMS screens or AFTO Form 203 is the next higher
echelon of equipment or system for the equipment covered by the subject TO. The functional system identifies an equipment
series if the TO being numbered covers an equipment sub-equipment series. The functional system identifies a system if the
TO being numbered covers an equipment series.
1.3.6.4 Part Number. A TO number will not normally be assigned to equipment without a part number, model number or
other identifier. All part numbers, model numbers or any other identifiers will be included in the TO title. If the equipment
is not already listed in ETIMS then the Equipment Specialists (ES) or Item Manager (IM) must enter it using the ETIMS
Maintain Equipment Screen. Data to be entered includes the weapon system application, the equipment part number, and the
manufacturer/vendor CAGE code. This data is then extracted from ETIMS for the TO-Equipment number Cross-Reference
section of the TO catalog.
1.3.6.5 Joint Electronics Type Designation System (JETDS) Nomenclature. Refer to Paragraph 1.19. If the JETDS
(formerly ″AN″) nomenclature appears in the title lines of a TO, it must be reflected in the TO number. Air Force personnel
request JETDS nomenclatures using a DD Form 61, Request for Nomenclature, submitted to the HQ AFMC Supply Opera-
tions Division, Asset Identification Branch (HQ AFMC/A4SI), Wright-Patterson AFB OH for approval. For further informa-
tion concerning this system contact A4SI at DSN 787-0610.
1.4 TECHNICAL ORDER NUMBERING PROCEDURES.
TO Managers requesting TO number assignment submit ETIMS Request TO Number screen or AFTO form 203 according
to procedures provided in TO 00-5-3. The TO numbering specialist will comply with the procedures and guidance provided
in the following paragraphs when assigning TO numbers to approved technical data.
1.4.1 DO86. Compare the Federal Stock Class (FSC), and D086, Mission Workload Assignments System, to determine if
the requesting LCMC or PC is responsible for the indicated FSC. Go to https://d086.wpafb.af.mil/ to view D086 informa-
tion. Review the title of the FSC to help determine the appropriate TO Category.
1.4.2 Determine Category. Using the FSC and equipment nomenclature, determine the appropriate TO category, equip-
ment series and sub-series. For numbering General TOs, see Paragraph 1.18.
1.4.3 Numbering Patterns. Once the category, series and sub-series have been determined, use the appropriate chapter of
this TO for proper numbering patterns within that category.
1.4.4 Developing TO Titles. Refer to Appendix B, Developing TO Titles, for guidance in developing a TO title. A TO
title is key to determining the correct TO number. TO titles will determine the type and kind of TO number assigned to a TO
and to prevent confusion between similar types of TOs covering similar applications. It will also be used to determine the
proper category a TO will be assigned, as well as, ensuring all segments of the number are in correct order and contain the
correct data. The TO numbering specialist will be unable to assign a TO number until incorrect information has been
corrected, which could delay the assigning of a TO number.
1.5 IDENTIFYING TYPES OF TECHNICAL ORDERS.
1.5.1 TO Types. Each of the various types of TOs: operations manuals, inspection and maintenance instructions, Illus-
trated Parts Breakdowns (IPBs), etc. is represented in a TO number by a designated type number (see Appendix C for a
complete list of types of TOs). These designated numbers are standard within a category, but are not necessarily standard
among categories. An example is a field maintenance manual, which is represented by ″-6″ in category 2, but is represented
by ″-2″ in other categories. Numbering specialists should consult the listings of designated numbers for the appropriate
category before assigning a number to represent a specific type of TO.
TO 00-5-18
1-5
1.5.2 Identifying TO Type. The type of TO is identified in the last basic group of the TO number and the first part of the
TO title. Normally this is the third or fourth group; however, in some categories it is necessary to identify an equipment
sub-series in the TO number. In these categories, the type of TO will be identified in the fifth group.
1.6 NUMBERING RELATED TECHNICAL ORDERS.
1.6.1 Authorized Numbers. Chapters 2 through 41 include complete lists of numbers authorized to identify specific types
of TOs in each TO category. The following list provides brief definitions of dedicated numbers used in all TO categories,
except categories 1, 21 and 22. (Additional numbers are required in categories 1, 21, and 22 to identify distinct types of TO
data.)
-01 List of Applicable Publications (LOAP)
-06 Work Unit Code Manuals
-1 Operating Instructions
-2 Organizational, Intermediate, Field Maintenance, or Service Manuals, Trouble Shooting & Repair Manual
-3 Depot Maintenance, Overhaul, Schematic, or Wiring Diagram Manuals
-4 Parts List, Parts Breakdown or Illustrated Parts Breakdown Manuals
-6 Inspection Requirement Manuals
-7 Installation and Installation Test Procedure Manuals
-8 Test Procedures, User Manuals, Reference Manuals, Programmed Test Manuals, or Software-Related In-
struction Manuals, Configuration Guide
-9 Alignment Instruction Manuals
NOTE
• The number -5 is used to identify a wide variety of types of TOs, depending on the applicable TO category.
Refer to Paragraph 1.12for numbering abbreviated TOs and to Paragraph 1.14for numbering TCTOs.
• The number -8 includes subsequent sequence numbers indicated as 8-1, 8-2, 8-x, etc. This sequence number is
used in all categories.
1.6.2 Compatable TOs. TO data pertaining to the same specific equipment, but contained in more than one type of TO
listed in subparagraph 1.9.1 above, is considered to be compatible and, therefore, is numbered together by using the same
basic TO number configuration. An operations manual, a maintenance manual and a parts breakdown manual that are
compatible will be numbered in the same TO number series, like those shown in the following examples:
36A12-13-18-1 Operations Manual
36A12-13-18-2 Maintenance Manual
36A12-13-18-4 Parts Breakdown
1.6.3 Equipment Modifications. Equipment modifications cause changes in TO data; and new TOs are issued to reflect
the changes. The new or modified TO data does not always replace existing TOs; therefore, it must be identified in the TO
number series that is already established. This identification is accomplished by determining the specific type of TO to be
numbered and adding 10 to the designator number (e.g., an operations manual, normally a ″-1,″ would become a ″-11″). This
addition provides another sequence for numbering slightly different TO data, pertaining to the same equipment, in the same
TO number series. Any subsequent operations manuals will be numbered -21, -31, -41, -51, etc. This 10-number sequence
within a TO number series preserves the integrity of the -1 designated number that identifies operations manuals; and it also
provides a method of grouping compatible TOs in the same sequence. This same sequence-numbering procedure will be
applied to various other types of TOs as required.
1.6.4 Non-Compatable TOs. Different types of TOs that relate to the same specific equipment, but contain data that is
not compatible, will be numbered with the same basic TO number, but will not be numbered in the same 10-number
sequence. For example, an operating instructions manual pertaining to specific equipment and a maintenance manual per-
taining to a modification of the same equipment are not compatible. The operating instructions manual will receive a basic
TO number ending in -1; and the maintenance manual will receive a TO number ending in -12 (in the subsequent 10-number
sequence). The same basic TO number will be used (e.g., 10E5-2-14-1 and 10E5-2-14-12).
TO 00-5-18
1-6
1.6.5 Numbering Similiar TO Types. Two TOs of the same type will not be numbered in the same 10-number sequence
of a TO number series. An intermediate maintenance manual and a service manual (each normally numbered -2) cannot be
numbered in the same 10- number sequence. One of the manuals will receive a basic TO number ending in -2 and the other
will receive the same basic TO number, but will end in -12 (from the following 10-number sequence). If a TO must be
changed to make it applicable to a specific configuration of the end item to which it applies and there are two or more end
item configurations to be covered, the original TO will retain its number unchanged and modified TOs will be identified by
a dash number in another 10-number sequence.
1.6.6 Sectionalisation of Numbers. If a TO is too large for efficient use, it may be sectionalized by dividing it into
logical equipment segments of two or more sections. Each of the sections will receive the same 10-number sequence
designator for the type of TO. A dash will be added and will be followed by a consecutive serial number to identify each
section (e.g., 12P6-4-14-3-1, 12P6-4-14-3-2, 12P6-4-14-3-3, 12P6-4-14-3-4). Sectionalizing is further described in Para-
graph 1.11.
1.7 NUMBERING FUNCTIONALLY ORIENTED MAINTENANCE MANUALS.
Functionally oriented maintenance manuals (FOMMs) will be numbered with a -2, to designate the type of TO, as described
in Paragraph 1.6and the appropriate section for the category involved. Section numbers may be assigned according to
Paragraph 1.11, if appropriate.
1.8 NUMBERING MAINTENANCE DEPENDENCY CHARTS.
Maintenance dependency charts will be numbered with a -2, like maintenance TOs.
1.9 NUMBERING CALIBRATION AND MEASUREMENT SUMMARIES TECHNICAL ORDERS.
Calibration and Measurement Summaries TOs will be numbered in the appropriate categories and TO series for the aero-
space systems (aircraft, missile, communications-electronics) to which they apply. Calibration and Measurement Summaries
TOs relating to general equipment, if no aerospace systems are identified, will be numbered in category 33K.
1.10 NUMBERING COMBINED TYPES OF TECHNICAL ORDERS.
For a TO that combines TO data relating to more than one type of TO, the designated number of the first type of TO
identified in the title will be assigned. Thus, a TO bearing the title ″Operations, Maintenance, and IPB″ will be numbered ″-
1″ because operations is the first type of TO identified in the title; a TO bearing the title ″Overhaul and IPB″ will be
numbered ″-3″ because overhaul is the first type of TO identified in the title. This numbering procedure will be used with
any combination of types of TOs and with CDs containing multiple TO types. When all system technical data is provided as
an Interactive Electronic Technical Manual (IETM) in a relational database, the number will identify the system (e.g., ″1F -
16C″) and end in ″-1″ to signify that all operations and maintenance data is contained in the database. If the database is
limited to maintenance data only, the number would end in ″-2.″ Paragraph 1.22 specifies number suffixes to use if there are
multiple TO versions published (e.g., the database and discrete TOs).
1.11 NUMBERING MULTIVOLUME (SECTIONALIZED) TECHNICAL ORDERS.
When TO data is sufficiently large and has natural divisions in tasks or equipment breakout which make several smaller
manuals more usable and more manageable, a separate TO number is assigned for each volume. One example that meets this
criterion is aircraft maintenance data, which contains many detailed tasks. The same procedures may be used for multiple
CD sets. Flight manual performance data may be issued as a separate TO numbered and assigned a suffix dash (-) number as
for multivolume TOs. Multivolume documents normally relate to the same system or equipment and are the same type of
TO. Different types of TOs will not be produced as separate volumes with the same basic TO number. After numbering
specialists have assigned the basic TO number and determined that a sectionalized manual is necessary, an additional group
will be added to the basic TO number. This new group will identify the volume number of a multivolume TO as in the
following examples:
12P3-2ALQ101-32-1
32 Maintenance Manual (Last Basic Group of TO Number)
1 First volume of a multivolume Maintenance Manual
TO 00-5-18
1-7
12P6-4-14-3-4
3 Overhaul Instructions Manual (Last Basic Group of TO Number)
4 Fourth volume of a multivolume Overhaul Instructions Manual
12P3-2ASR5-4-2
4 Illustrated Parts Breakdown (Last Basic Group of TO Number)
2 Second volume of a multivolume Illustrated Parts Breakdown Manual
1.12 NUMBERING ABBREVIATED TECHNICAL ORDERS.
Abbreviated TOs, including checklists (CL), workcards (WC), etc., are identified by adding the alpha designator to the last
group of the TO number and adding a sequential number (-1, -2, -3, etc.) to identify the TO as the first, second, third, etc. in
a series.
Examples: 1F-15A-2-10CL -1
31S5-2FYQ45-6WC-2
1.13 NUMBERING SUPPLEMENTAL MANUALS.
A supplemental manual does not stand alone, but must be used in conjunction with another TO. Supplemental manuals may
be used to publish classified data while allowing the parent manual to remain unclassified, to publish data provided by a
source other than the PM, and/or to publish data in a form other than the parent manual. Supplemental manuals differ from
supplements in that they are assigned a separate TO dash number with no alpha designations. The TO identification number
for supplemental manual is established by adding a serial number to the parent TO number. The first supplemental manual is
-1, the second is -2, etc.
Examples: 31S5-2FYQ45-3-1 is a supplemental manual used with 31S5-2FYQ45-3.
1F-4D-34-1-1-1 is a supplemental manual used with 1F-4D-34-1-1.
1.14 NUMBERING TIME COMPLIANCE TECHNICAL ORDERS.
1.14.1 TCTO. A time compliance technical order (TCTO) contains technical instructions for the modification or inspec-
tion of a specific item of Air Force equipment, or distribution of revised CPIN items. A TCTO may also cause publication of
a change or supplement to technical data already established in the TO system. A TCTO is identified by a serial number
beginning with the number 501 for the first TCTO issued for the item of equipment, and its basic number indicates data that
has already been numbered in the TO system. Since a TCTO may affect more than one type of manual, a type-of-manual
designator is not included in the TCTO number. The TCTO serial number replaces the type-of-manual designator in the basic
TO number. See TO 00-5-3.
1.14.1.1
Examples: 1F-111A-1254
16G1-148-501
21M-LGM30-1030
31P5-2MPN14-534
35A2-2-76-501
1.14.1.2 When a requirement exists to reactivate a TCTO that has been rescinded, the TCTO will be reinstated with the
same TCTO number, but with a current date. The number of an inactive TCTO is never reused for a different modification
or inspection.
1.14.1.3 If a program was formerly operating outside of the standard Air Force TO numbering policies/procedures, they
may request a waiver to continue use of the non-standard formats and avoid the cost of converting existing TOs and TCTOs.
1.14.2 TCTO Supplement. A TCTO supplement is identified by adding an alpha suffix to the TCTO serial number; e.g.,
16G1-149-501C.
TO 00-5-18
1-8
1.14.3 TCTO Series Header. A TCTO series header includes only those TO number groups necessary to identify the
model, type, or part number of a specific item of equipment. Separate series headers are required for each different classi-
fication of TCTO to be issued. They usually contain two or three groups.
1.14.3.1
Examples: 1F-111A [S] (Secret TCTOs)
16G1-148
21M-LGM30 [C] (Confidential TCTOs)
31P5-2MPN14
35A2-2-76
1.14.3.2 Broadly applicable series headers, such as ″35A2 - Jacks,″ could encompass equipment managed by different
program offices, and this could possibly result in multiple TO Managers issuing TCTOs against a header established by one
of them.
1.14.3.3 The following are exceptions to the length of a TCTO Series Header number.
1.14.3.3.1 For a depot level supplemental FMS TO to an Air Force TO, when the supplemental TO only includes FMS
part numbers and country codes for each part. These TOs will be used by Air Force assets to maintain foreign aircraft and
will not be releaseable to the foreign country. Since these TOs have a very specific TO number and will only be releaseable
to Air Force accounts, but will be used on foreign aircraft, special TCTO series headers will need to be created for each TO
to include an XX at the end of the TCTO series header number, for example, 12P3-2ALE47-3-1 and 12P3-2ALE47-4-1
would be the supplemental TO numbers and will require FMS use only in the title. The TCTO series header will then be
12P3- 2ALE47-XX and will cover all TOs in the FMS series of the TOs and must include the TO numbers of the FMS only
supplemental TOs.
1.14.3.3.2 Due to large amounts of systems being added to the Air Force where the TO number does not include a part
number, but includes the system number, for example 31S9-4-122-2-WA-1, where the 122 position is associated to a system
and not a part number, TCTO series headers will be required to go beyond the second and third series of number, since these
TCTOs will cover several parts that make up the entire system. This will allow the TCTO to be distributed to just the users
of a particular system and prevent the distribution of TCTOs to users that have different systems that fall into a series of
TOs.
1.14.4 Establishing TCTO Series Header. To establish a TCTO series header, the TO Manager submits a ETIMS screen
according to the DI, or AFTO Form 203 IAW TO 00-5-3. When it is expected that a TCTO covering more than one item of
equipment will be forthcoming, a general TCTO series listing will be established at the appropriate level of generality.
1.14.4.1
Examples: 1F-1 Applicable to More Than One Fighter Aircraft
1F-111 Applicable to More Than One Series of F-111 Aircraft
1F-111A Applicable Only to the A Series of F-111 Aircraft
1.14.4.2 The mission-design-series (MDS) designators assigned to the B-1, H-1, and T-1 aircraft caused necessary excep-
tions to be made when numbering general TCTO series and general TOs for these three categories of aircraft. Since the
aircraft MDS are the same as normally used for system general TCTO series listings, the number zero (0) is used in the
second group of the number to designate a TCTO applying to more than one aircraft series.
1.14.4.3
Examples: 1B-0 Applicable to all bomber aircraft.
1B-1 Applicable to all models of the B-1 aircraft.
1B-1B Applicable to the B-1B aircraft.
1H-0 Applicable to all helicopter aircraft.
1H-1 Applicable to all models of the H-1 helicopter.
TO 00-5-18
1-9
1H-1H Applicable to the H-1 helicopter, model H.
1T-0 Applicable to all trainer aircraft.
1T-1A Applicable to the T-1 trainer, model A.
1.14.5 Requesting TCTO Numbers. TO Managers request individual TCTO numbers through ETIMS, which automati-
cally assigns the next consecutive serial number within the header series. ETIMS will assign the correct data code.
1.15 EMERGENCY TECHNICAL ORDER NUMBERING REQUESTS.
Timely submittal of TO numbering requests will minimize the use of emergency procedures. In the event of a work stoppage
or other justified emergency, the TO Managers will use procedures in TO 00-5-3.
1.16 RENUMBERING TECHNICAL ORDERS.
TO renumbering shall be held to the minimum necessary to correct serious TO numbering errors. Renumbering will not be
accomplished to align TO numbers with local sequence numbers or other cross reference identifiers. TO numbers will not be
cancelled and new TO numbers assigned just for the purpose of renumbering. The responsible TO Manager will renumber a
TO using the ETIMS ″Manage TOs, Manager TO Detail″ process after coordinating the new number with AFLCMC/LZPT-
Tinker. (Coordination is not required to assign a TO supplement number, or change an FMP supplement number.) When
renumbering a published TO, both the new and former TO numbers will appear in the upper right corner of the title page
with the former number preceded by the word ″Formerly″. Both numbers will remain on the title page until the next
revision, at which time only the new number will appear. Only the new TO number will appear on the individual updated
pages. Unchanged pages will continue to indicate the old TO number until they are changed for a reason other than simply
renumbering, or until the next TO revision.
NOTE
TOMA must contact local TO Home Office, who will coordinate with AFLCMC/LZPTP-Tinker prior to renum-
bering a TO to ensure a proper number is being used.
1.17 ASSIGNING TECHNICAL ORDER NUMBERS TO OTHER DOD COMPONENT TECHNICAL MANUALS.
TO numbers will be assigned to other DoD component Technical Manuals (TMs) that are adopted for Air Force use
according to AFJI 21-301. The Army numbering patterns for TMs are described in Department of the Army Pamphlet (DA
PAM) 25-30, Consolidated Index of Army Publications and Blank Forms. To assign appropriate Air Force TO numbers to
Army TMs, research DA PAM 25-30, this TO, and other appropriate source data. Navy, Marine Corps and Defense Logistics
Agency TMs are given AF TO numbers in a similar fashion.
1.17.1 Army TM Designators. Table 1-2 provides a list of the most common types of technical manual designators used
for Army TMs and corresponding Air Force type of TO designators. This table is provided as an aid but should not be used
to make final determination of an Air Force TO number.

1.18 GENERAL TECHNICAL ORDERS.
In the numbering patterns for each category described in Chapters 2 through 41, numeric characters are used in the second
or third group of a TO number to identify the specific equipment covered by the TO. The distinct pattern for a category, or
a system within a category, indicates whether the second or third group is used for the specific equipment identifier. The
number used as a specific equipment identifier will be greater than 1.
1.18.1 General TO Numbers. If the number 1 is used in lieu of a specific equipment identifier, the TO is a general
technical order (category general, system general, or equipment-series general TO). EXCEPTION: The pattern established
for numbering TCTO series for B-1, H-1, and T-1 aircraft ( Paragraph 1.14.4.2 & Paragraph 1.14.4.3) is also used for general
TOs in these systems.
1.18.1.1 Category general TOs apply to more than one type of aircraft, missile, or engine or to more than one equipment
system in the category.
1.18.1.2 System general TOs apply to more than one type of aircraft, missile, or engine or to more than one equipment
series within the equipment system.
1.18.1.3 Equipment-series general TOs apply to more than one sub-series of equipment within the equipment-series.
Examples: TO Number
Equipment-Series
9H1-1-102 Accumulators
9H2-1-102 Cylinders and Actuators
34C1-1-101 Leather Cutting Machines
34F2-1-111 Metal Finishing Machines
36A1-1-141 Ambulances
36A2-1-1 Commercial Fleet Vehicles
1.18.1.4 Equipment-sub-series general TOs apply to more than one equipment within the equipment sub-series.
Examples: TO Number
Equipment-Sub-Series
34F2-2-1-111 Grinders
34F2-3-1-121 Hones
36A2-3-1-1-3 Ford Vehicles

36A2-5-1-104 Chrysler Motors Vehicles
1.19 NUMBERING JOINT ELECTRONICS TYPE DESIGNATION SYSTEM (JETDS) TECHNICAL ORDERS.
1.19.1 JETDS Numbers. A large portion of the TOs in categories 12 and 31 cover equipment identified by JETDS
equipment numbers. The JETDS (formerly AN nomenclature system) is described in MIL-STD-196, Joint Electronics Type
Designation System.
TO 00-5-18
1-11
1.19.1.1 A typical JETDS equipment number is AN/APN-167. The alphas AN indicate JETDS equipment. The A (first
alpha character following the diagonal) designates the installation as piloted aircraft. The P (second alpha character follow-
ing the diagonal) designates the type of equipment as radar. The N (third alpha character following the diagonal) designates
the purpose of the equipment as navigational aids. The number following the dash designates a specific set of equipment.
Table 1-3 provides a complete list of equipment indicators.
1.19.1.2 A typical JETDS component number is RT-771/APN-167. The RT, in accordance with MIL-STD-196 indicates a
receiver and transmitter. The 771 identifies a specific equipment component. The APN-167 (following the diagonal) indicates
the component is applicable to the AN/APN-167 equipment set described above.
1.19.1.3 Identifying numbers for TOs covering JETDS equipment and components use a portion of the JETDS number in
the second group of the TO number. (See examples of TO numbers in Chapter 15 and Chapter 22 .)
1.19.1.4 If a single TO is applicable to more than one JETDS equipment set or component at any level of breakdown, a
JETDS general TO may be established at that level.
1.19.2 JETDS General TOs. JETDS system-general TOs apply to equipment sets in more than one kind of JETDS
installation. These TOs are identified by the numeric 2 in the second group of the TO number. Examples:
• 31P5-2-137 is applicable to both fixed ground installation (indicated by the F following the diagonal in AN/FSA-4A
which is identified in the title) and general ground-use (indicated by the G following the diagonal in AN/GRC-30
which is identified in the title).
• 31W4-2-121 is applicable to both general utility installation (indicated by the U following the diagonal in SB-
1203/UG which is identified in the title) and water installation (indicated by the S following the diagonal in
TT-23/SG which is identified in the title).
1.19.3 JETDS Installation TOs. JETDS installation-general TOs apply to equipment sets in more than one JETDS type
of equipment within one installation kind. The second group of the TO number will contain a 2 followed by an alpha
character that designates the installation kind. Examples:
• 31W4-2G-101 is applicable to a general, general-ground-use component C-7185/G.
• 31W4-2T-102 is applicable to a general-use, ground transportable component CU-1819/T.
1.19.4 JETDS Equipment TOs. JETDS equipment-type general TOs apply to more than one equipment purpose within
one type of equipment. The second group of the TO number will contain a 2 followed by an alpha character that designates
the equipment installation kind and a second alpha character that designates the type of equipment. Examples:
• 31W4-2GG-162 is applicable to a general-use component CV-2696/GG. The first G after the diagonal indicates
general ground-use installation. The second alpha indicates telegraph or teletype type of equipment.
• 31W4-2TG-144 is applicable to a general-use component TH-5/TG. The T following the diagonal indicates a
ground transportable installation. The G indicates the type of equipment is telegraph or teletype.
1.19.5 JETDS General Purpose TOs. JETDS purpose general TOs apply to more than one specific equipment set
within one equipment purpose. The second group of the TO number will contain a 2 followed by three alpha characters that
designate the installation, type of equipment, and purpose, respectively. Examples:
• 31W4-2GGC-142 is applicable to components OU-60/GGC-30 and OU-61/GGC-31.
• 31W4-2TGC-122 is applicable to equipment sets AN/TGC-27 and AN/TGC-28.

1.20 COUNTRY STANDARD TECHNICAL ORDER NUMBERS.
1.20.1 Country Standard TO. Country Standard TO (CSTO) numbers are assigned to readily identify TOs that support
equipment acquired by foreign countries through the Foreign Military Sales Program. These TOs are not used by the United
States Air Force (USAF), but are centrally managed by AFLCMC/LZPTC-Tinker, Tinker AFB OK, in the Security Assis-
tance Technical Order Distribution System (SATODS) for support of the foreign customers. A CSTO may be a complete
standalone publication or it may be a supplemental manual containing difference data used in conjunction with a baseline
TO.
TO 00-5-18
1-13
1.20.2 CSTO Designation. CSTO numbers are distinguished from USAF TO numbers by using ″CSTO″ in place of
″TO″ and with a two- position alpha prefix (country designator) that identifies the country involved. The balance of the
CSTO number is established in the same manner described in this document for USAF TOs. Country designators will be
compatible with country codes listed in AFMAN 23-110, Vol 9, Security Assistance Program Procedures and DOD Manual
5105.38-M, Security Assistance Management Manual (SAMM), Appendix 4.
1.20.3 Standalone CSTO. If the CSTO is a standalone publication used in lieu of a USAF TO, the CSTO will be
identified by a country designator plus the same number as the related USAF TO. Only the acronym ″CSTO″ and country
designator prefix in the CSTO number will distinguish between them.
NOTE
Supplemental manuals will have a title page statement reading ″This TO (or CSTO) is incomplete without TO (or
CSTO) (number).″
1.20.4 CSTO Coutry Designator. When the CSTO is supplemental to a USAF TO or to a standalone CSTO, it will be
identified by a country designator prefix plus a -1 or other appropriate designation added to the TO number according to the
concept described in Paragraph 1.13.
1.20.5 CSTO Component Equipment. In some instances a standalone CSTO will be for component equipment of a
major design departure from any USAF equipment; therefore, it will not be related to any USAF TO.
1.20.6 CSTO Examples. Examples of CSTOs are as follows:
• Standalone CSTO - Job guide manual used by Saudi Arabia for F-15 aircraft:

1.21 OPERATION AND MAINTENANCE INSTRUCTIONS IN WORK PACKAGE FORMAT.
1.21.1 Work Package Format. Operation and maintenance instructions in work package format and subordinate work
package format are prepared according to MIL-PRF-87929. The complete TO, which consists of a set of work packages, is
numbered according to numbering procedures for the specific equipment category.
1.21.2 Individual Work Packages. Individual work packages will be numbered by the TO Manager using the following
criteria:
1.21.2.1 The number will consist of five numeric characters and an alpha prefix of WP or SWP to identify a Work Package
or a Subordinate Work Package as defined in MIL-PRF-87929.
1.21.2.2 A work package will be identified in the first three numeric positions; the last two numeric positions will be zeros
(e.g., WP 116 00).
1.21.2.3 A subordinate work package will be identified by using the first three positions to specify the work package and
the last two positions to specify the subordinate work package (e.g., SWP 126 19).
1.21.2.4 The alphabetical index work package (as defined in MIL-M-87929) will always be the first work package in the
TO (i.e., WP 001 00).
1.21.2.5 The introduction work package (as defined in MIL-PRF-87929) will always be the second work package in the
TO (i.e., WP 002 00).
1.21.2.6 Other work packages will be numbered WP 003 00, WP 004 00, and so on as required.
1.22 TECHNICAL ORDER DISTRIBUTION MEDIA SUFFIX CODES.
NOTE
Detailed instructions on the use of Distribution Media Codes are listed in TO 00-5-3.
1.22.1 Different Media Types. To meet customer requirements TO Managers may offer the same technical data on two or
more types of distribution media, such as paper, CD-ROM, or DVD; as well as through direct electronic access.
1.22.2 Media Suffix Codes. Distribution media suffix codes (see below) are used in index listings to identify any TO
versions available in any media other than paper, and will allow users to order TO copies distributed on that medium. Index
listings for non-paper versions of the TO will include the applicable distribution media suffixes followed by an index
number. Media-type suffixes will not be used for paper copies. TO media-type suffix codes are:
Code
Medium
CD CD-ROM
WA Electronic Access (Web Access (digital))
DV Digital Versatile Disk (DVD)
TO 00-5-18
1-15
NOTE
Distribution media suffixes appear only in the TO Index for ordering purposes. They are not placed on the TOs
themselves unless they are part of the digital distribution medium’s number.
1.22.3 Media Suffix Recognition. The media-type suffix code will allow sight recognition of TOs available on other-
than-paper media. All media-type suffixes will carry the index number ″-1,″ except as described below. The index number
following the suffix will be used for several purposes:
1.22.3.1 If a TO or set of TOs ( Paragraph 1.23 ) requires more than one disk or tape, the index number will indicate
individual disks/tapes in the set (i.e., disk one of three is -1, disk two of three is -2, and disk three of three is -3).
1.22.3.2 If a set of TOs contains manuals with different classifications or distribution limitations, these TOs may be
segregated by disk with different index numbers assigned to the different levels of protection required.
1.22.4 Examples.
• TO 1B-52G-4-1 is a paper IPB for the B52G aircraft. A DVD containing this TO would be indexed as 1B-
52G-4-1-DV-1.
• TO 12P2-2APQ120-2 is an intermediate maintenance manual for a radar indicator. A CD-ROM containing the same
TO would be indexed 12P2-2APQ120-2-CD-1.
• TO 33K-1-100-CD-1 (calibration procedures) is only available on CD-ROM.
• The database for the F-22 fighter Interactive Electronic Technical Manual (IETM) will be available on-line through
a WAN, and would be indexed as 1F-22A-1-WA-1, with a Catalog note on how to access it. Note that the basic TO
number ends in ″-1″ because ALL procedures, operations and maintenance, are contained in the one database (see
Paragraph 1.10).
1.23 CD-ROMS/DVDS.
If a single TO or multiple TOs will be distributed on a CD-ROM or DVD, the TOMA must establish a specific TO Number
for the CD ROM or DVD distributed. These actions will ensure that users will be able to subscribe to the CD-ROM/DVD
TO or collection of TOs. EXAMPLES:
• TO 1B-52H-2-CD-1 through 1B-52H-2-CD-5 would contain the Organizational Maintenance Manual Set for the
B-52H, provided on a set of 5 CD-ROMs;
• TO 33D2-17-2-CD-1 would contain unclassified TOs on an Aircraft Field Test Stand provided on CD-ROM, while
33D2-17-2-CD-2 (C) would contain confidential TOs for the same equipment; and
• TO 35D-1-DV-1 would be unclassified, Distribution Statement A TOs for Miscellaneous Aircraft Loading and
Servicing Equipment provided on DVD.
1.24 TECHNICAL ORDER NUMBERING FOR ASD/AIA S1000D©, INTERNATIONAL SPECIFICATION FOR
TECHNICAL PUBLICATIONS UTILIZING A COMMON SOURCE DATABASE.
1.24.1 S1000D. ASD/AIA S1000D© (http://www.s1000d.org) contains three primary constructs that relate directly to the
TO Numbering process. These constructs are the Data Module (DM), the Common Source Data Base (CSDB), and the
Publication Module (PM).
1.24.1.1 The DM is a self-contained unit of data for the description, operation, identification of parts or maintenance of
the product and its support equipment. The DM consists of an identification and status section and contents section, and is
produced in such a form that it can be input into, and be retrieved from, a database using a defined identifier.
1.24.1.2 The CSDB is a ″store″ of DMs required to produce technical publications.
1.24.1.3 The PM defines the content and the structure of a publication.

1.24.2 S1000D Compliance. TO numbers shall be assigned to the CSDB and each PM when acquiring ASD/AIA
S1000D-compliant TOs. TO numbers for CSDBs shall comply with the TO numbering for databases as described in this TO
( Paragraph 1.10). TO numbers for PMs shall also comply with this TO, but will use the Publication Module Code as
specified in ASD/AIA S1000D as part of the TO number. DMs shall not receive a TO number, but will be numbered and
controlled by ASD/AIA S1000D Data Module Code.

CHAPTER 3
CATEGORY 00 - METHODS AND PROCEDURES TECHNICAL ORDERS
3.1 GENERAL.
AFMC/A4FI establishes responsibilities for preparing Category 00 Methods and Procedures TOs (MPTOs). When a TO
Manager requests a new Category 00 TO number, AFLCMC/LZPTP-Tinker determines if A4UE coordination and approval
have been obtained before assigning a TO number.
3.1.1 00 TO Category. Category 00 TOs contain management data or data which is related to multiple equipment
categories; or data which cannot be identified with any other established category.
3.1.2 00 TO Numbering Pattern. The TO numbering pattern in Category 00 uses three basic groups. A fourth group is
sometimes added to further separate MPTOs or to sectionalize by equipment subdivisions as described in the introduction.
The numbering pattern is explained in Paragraph 3.2.
3.2 NUMBERING PATTERNS.
3.2.1 Group One. This group contains one part. The designator 00 identifies the TO as being an MPTO.
3.2.2 Group Two. This group contains two parts.
3.2.2.1 Part one is made up of one or more numeric characters that identify the subject matter series. The numbering series
are listed in Paragraph 3.4.
3.2.2.2 Part two, when used, consists of one or more alpha characters that further breakdown the subject matter into sub-

CATEGORY 3 - AIRCRAFT PROPELLERS AND ROTORS
6.1 GENERAL.
6.1.1 Aircraft Propellers and Rotors Category 3. Category 3 has four major divisions: one for each of the three types of
propellers and one for rotor assemblies. TO numbers for propellers use three basic groups. TO numbers for propellers
associated equipment use both three and four basic groups.
6.1.2 Multiple Propeller Assemblies. TO data pertaining to more than one type of propeller assembly control is num-
bered in the category general series.
6.1.3 Multiple Propeller Motivations. Information pertaining to more than one propeller assembly, within one type of
propeller control motivation, is numbered in the propeller control general series.
6.2 NUMBERING PATTERNS.
6.2.1 Group One. This group has three parts identifying the category, type of propeller control and equipment series.
6.2.1.1 Part one is always the numeric 3 that identifies Category 3.
6.2.1.2 Part two identifies the type of aircraft propeller control by using alpha designators, i.e., E - electrical control; H -
hydraulic control; and M - mechanical control. Rotor assemblies and equipment are designated by an R identifier in part two.
Aircraft propeller associated equipment is identified by adding the alpha character A after the propeller control identifier, i.e.,
EA, HA, and MA. Rotor assemblies do not have associated equipment identified in the TO system.
6.2.1.3 Part three of this group identifies an equipment series representing further breakout of each type of propeller, its
associated equipment and rotor assemblies. A listing of the series numbers is included in Paragraph 6.4.
6.2.2 Group Two. TO numbering patterns in Category 3 use both three and four basic groups; therefore, the identifiers in
group two are not constant. The following describes the numbering pattern for both groups:
6.2.2.1 If only three basic groups are used in the numbering pattern, group two contains one or more numeric characters
representing the model, type or PN assigned to specific equipment.
6.2.2.2 If the TO number contains four basic groups, the equipment series has been further divided into equipment
subseries. In this case the subseries is identified with one or more numeric characters in group two and the model, type or PN
is identified in group three.
6.2.3 Group Three.
6.2.3.1 If a TO number has only three basic groups, the third group identifies the type of TO (see Appendix C for a
complete list of types of TOs). The following is a list of numbers reserved to identify specific types of TOs in Category 3:
-1 Operating Instructions
-2 Service or Maintenance Instructions
-3 Depot Maintenance or Overhaul Instructions
-4 Illustrated Parts Breakdown
-6 Inspection Requirements
6.2.3.2 In some instances the reserved numbers in the third group are followed by one or more alpha characters indicating
a series of checklists, workcards, and supplements. The following alpha characters are authorized for use in Category 3:
CL - Checklists
TO 00-5-18
6-1
S - Operational Supplements
SS - Safety Supplements
WC - Workcards
6.2.3.3 If the TO number contains four basic groups, the third group will have one or more numeric characters represent-
ing the model, type, or PN assigned to specific equipment.
6.2.4 Title Group Four. In those cases where the TO number has four basic groups, the fourth group identifies specific
types of TOs as described in Paragraph 6.2.3.1 above.

CATEGORY 5 - AIRBORNE INSTRUMENTS
8.1 GENERAL.
Category 5 contains seven aircraft and missile instrument systems. These systems are divided into equipment series and most
of the systems are further divided into equipment subseries within each equipment series. Therefore TO numbers in Category
5 use both three and four basic groups for data identification. Numbering patterns for both groups are identified in Paragraph
8.2.
8.1.1 Airborne Instruments Category 5. TO data pertaining to more than one system is numbered in the category
general series.
8.1.2 Multiple Systems. Information pertaining to more than one series within a system is numbered in the system
general series.
8.2 NUMBERING PATTERNS.
8.2.1 Group One. This group has three parts identifying the category, system, and equipment series within the system.
8.2.1.1 Part one is always the numeric 5 identifying Category 5.
8.2.1.2 Part two is an alpha character identifying the instrument system, i.e., A - automatic flight control; E - engine
instruments; F - flight instruments; L - liquid measuring instruments; M - electric circuit instruments; N - navigation
instruments; and P - position and pressure instruments. Flight instruments is the only system that has associated equipment;
it is identified by the system identifier FA.
8.2.1.3 Part three contains one or more numeric characters identifying an equipment series within a system. The TO
numbering series is outlined in Paragraph 8.4.
8.2.2 Group Two. TO numbering patterns in Category 5 use both three and four basic groups; therefore, the identifiers in
group two are not constant. The following describes both numbering patterns:
8.2.2.1 If the TO number uses only three basic groups, group two will have one or more numeric characters representing
the model, type or PN assigned to specific equipment.
8.2.2.2 If the TO number contains four basic groups, the equipment series identified in part three of group one has been
further divided into equipment subseries. In this case group two identifies the equipment subseries with one or more numeric
characters and the model, type or PN identified in group three.
8.2.3 Group Three.

CHAPTER 9
CATEGORY 6 - AIRCRAFT AND MISSILE FUEL SYSTEMS
9.1 GENERAL.
Category 6 has six primary aircraft and missile fuel systems. These systems are divided into equipment series and further
divided into equipment subseries within each equipment series. TO numbers in Category 6 will use both three and four basic
groups for data identification. Numbering patterns for both groups are discussed in Paragraph 9.2.
9.1.1 Aircraft and Missile Fuel Systems Category 6. TO data pertaining to more than one system is numbered in the
category general series.
9.1.2 Mutiple Systems. Information relating to more than one equipment series within a system is numbered in the
system general series.
9.2 NUMBERING PATTERNS.
9.2.1 Group One. This group has three parts identifying the category, system and equipment series within the system.
9.2.1.1 Part one is always the numeric 6 identifying Category 6.
9.2.1.2 Part two is an alpha character which identifies the fuel system, i.e., A - air refueling; J - aircraft and missile jet
engine fuel systems; K - Depot Maintenance or Overhaul Instructions; P - purging system; R - reciprocating engine fuel
systems; and S -offensive systems. There is no associated equipment identified in this category.
9.2.1.3 Part three contains one or more numeric characters that identify an equipment series within a system. The TO
numbering series is outlined in Paragraph 9.4.
9.2.2 Group Two. TO numbering patterns in Category 6 use both three and four basic groups; therefore, the identifiers in
group two are not constant. The following describes both numbering patterns:
9.2.2.1 If the TO number uses only three groups, group two will have one or more numeric characters representing the
model, type or PN assigned to specific components.
9.2.2.2 If the TO number contains four groups, the equipment series identified in part three of group one has been further
divided into equipment subseries. In this case group two identifies the equipment subseries with one or more numeric
characters and the model, type or PN is identified in group three.
9.2.3 Group Three.
9.2.3.1 If a TO number has only three basic groups, the third group identifies the type of TO (see Appendix C for a
complete list of types of TOs). The following is a list of numbers reserved to identify specific types of TOs in Category 6:
-1 Operating Instructions
-2 Service or Maintenance Manuals
-3 Depot Maintenance or Overhaul Instructions
-4 Illustrated Parts Breakdown
-6 Inspection Requirements
-7 Installation Instructions and Installation Test Procedures
-8 Test Procedures, Checkout Manuals, or Programmed Tests
TO 00-5-18
9-1
9.2.3.2 In some instances the reserved numbers in group three are followed by one or more alpha characters indicating a
series of checklists, workcards, or supplements. The following alpha characters are authorized for use in Category 6:
CL - Checklists
S - Operational Supplements
SS - Safety Supplements
WC - Workcards
9.2.3.3 If the TO number has four basic groups, the third group contains one or more numeric characters representing the
model, type or PN assigned to specific component assemblies.
9.2.4 Group Four. If the TO number has four basic groups, the fourth group identifies specific types of TOs described in
Paragraph 9.2.3.1 above.
9.3 EXAMPLES OF CATEGORY 6 NUMBERING PATTERNS.
9.3.1 Example One. Overhaul instructions with parts breakdown for a fuel filter assembly, PN 52-2145-002, for H-43B
helicopter:
6R2-19-3

CATEGORY 7 - AIRBORNE ENGINE LUBRICATING SYSTEMS
10.1 GENERAL.
Category 7 has only two systems relating to airborne engine lubrication. These two systems are divided into equipment
series and then further divided into equipment subseries within each equipment series. TO numbers in Category 7 use both
three and four basic groups for data identification. Numbering patterns for both groups are discussed in Paragraph 10.2.
10.1.1 Multiple Systems. TO data pertaining to more than one system is numbered in the category general series.
10.1.2 Multiple Series. Information involving more than one equipment series within a system is numbered in the system
general series.
10.2 NUMBERING PATTERN.
10.2.1 Group One. This group has three parts identifying the category, system and equipment series within the system.
10.2.1.1 Part one is always the numeric 7 identifying Category 7.
10.2.1.2 Part two is an alpha character that identifies the lubrication system. These alpha characters are: J - jet engine
lubricating systems, or R - reciprocating engine lubricating systems. There is no associated equipment identified in this
category.
10.2.1.3 Part three contains one or more numeric characters identifying an equipment series within a system. The TO
numbering series is outlined in Paragraph 10.4.
10.2.2 Group Two. TO numbering patterns in Category 7 use both three and four basic groups; therefore, the identifiers
in group two are not constant. The following describes both numbering patterns:
10.2.2.1 If the TO number uses only three basic groups, group two will have one or more numeric characters representing

CHAPTER 11
CATEGORY 8 - AIRBORNE ELECTRICAL SYSTEMS
11.1 GENERAL.
Category 8 contains six airborne electrical systems. These systems are divided into equipment subseries within each equip-
ment series. Therefore TO numbers in Category 8 use both three and four basic groups for data identification. Numbering
patterns for both groups are discussed in Paragraph 11.2.
11.1.1 Multiple Systems. TO data pertaining to more than one system is numbered in the category general series.
11.1.2 Multiple Series. Information relating to more than one equipment series within a system is numbered in the system
general series.
11.2 NUMBERING PATTERNS.
11.2.1 Group One. This group has three parts identifying the category, system and equipment series within a system.
11.2.1.1 Part one is always the numeric 8 identifying Category 8.
11.2.1.2 Part two is an alpha character identifying the electrical system, i.e., A - alternating current electrical equipment;
C - combination of both alternating and direct current electrical equipment; D - direct current electrical equipment; E -
ignition systems; R - relays; and S - switches.
11.2.1.3 Part three contains one or more numeric characters identifying an equipment series within the system. The TO
numbering series is outlined in Paragraph 11.4.
11.2.2 Group Two. Since TO numbering patterns in Category 8 use both three and four basic groups, the identifiers in
group two are not constant. The following explains the numbering patterns for both groups:
11.2.2.1 If the TO number uses only three basic groups, group two will have one or more numeric characters representing
the model, type or PN assigned to specific components.
11.2.2.2 If the TO number contains four basic groups, the equipment series identified in group one, part three, has been
divided into equipment subseries. In this case group two identifies the equipment subseries with one or more numeric
characters and the model, type or PN is identified in group three.
11.2.3 Group Three. .
11.2.3.1 If a TO number has only three basic groups, the third group identifies the type of TO (see Appendix C for a
complete list of types of TOs). The following is a list of numbers reserved to identify specific types of TOs in Category 8:
-1 Operating Instructions
-2 Service or Maintenance Manuals
-3 Depot Maintenance or Overhaul Instructions
-4 Illustrated Parts Breakdown
-6 Inspection Requirements
-7 Installation Instructions and Installation Test Procedures
-8 Test Procedures, Checkout Manuals, or Programmed Tests
TO 00-5-18

11.2.3.2 In some instances, the reserved numbers in group three are followed by one or more alpha characters indicating
a series of checklists, workcards, or supplements. The following alpha characters are authorized for use in Category 8:
CL - Checklists
S - Operational Supplements
SS - Safety Supplements
WC - Workcards
11.2.3.3 If the TO number has four basic groups, the third group contains one or more numeric characters representing
model, type or PN assigned to specific equipment and the specific types of TOs are then identified in group four.
11.2.4 Group Four. If the TO number has four basic groups, the fourth group identifies specific types of TOs described in
Paragraph 11.2.3.1.
11.3 EXAMPLES OF CATEGORY 8 NUMBERING PATTERNS.
11.3.1 Example One. Operating and maintenance instructions with illustrated parts breakdown for an alternating current

CATEGORY 9 - AIRCRAFT AND MISSILE HYDRAULIC, PNEUMATIC AND
VACUUM SYSTEMS
12.1 GENERAL.
Category 9 contains airborne hydraulic, pneumatic, and vacuum systems. These systems are divided into equipment series
and further divided into equipment subseries within each equipment series. TO numbers in Category 9 use both three and
four basic groups for data identification. Numbering patterns for both groups are discussed in Paragraph 12.2.
12.1.1 Multiple Systems. TO data pertaining to more than one system is numbered in the category general series.
12.1.2 Multiple Equipment. Information relating to more than one equipment series within a system is numbered in the
system general series.
12.2 NUMBERING PATTERNS.
12.2.1 Group One. This group has three parts identifying the category, system and equipment series within a system.
12.2.1.1 Part one is always the numeric 9 that identifies Category 9.
12.2.1.2 Part two is an alpha character indicating the system, i.e., H - hydraulic systems; P - pneudraulic systems; and V
- vacuum systems.
12.2.1.3 Part three contains one or more numeric characters identifying the equipment series within a system. These TO
numbering series are outlined in Paragraph 12.4.
12.2.2 Group Two. Since TO numbering patterns in Category 9 use both three and four basic groups, the identifiers in
group two are not constant. The following explains both numbering patterns:
12.2.2.1 If the TO number uses only three basic groups, group two will have one or more numeric characters representing
the model, type or PN assigned to specific components.
12.2.2.2 If the TO number contains four basic groups, the equipment series identified in group one, part three, has been
divided into equipment subseries. In this case, group two identifies the equipment subseries with one or more numeric
characters and the model, type or PN is identified in group three.
12.2.3 Group Three.
12.2.3.1 If a TO number has only three basic groups, the third group identifies the type of TO (see Appendix C for a
complete list of types of TOs). The following is a list of numbers reserved to identify specific types of TOs in Category 9:
-1 Operating Instructions
-2 Service or Maintenance Manuals
-3 Depot Maintenance or Overhaul Instructions
-4 Illustrated Parts Breakdown
-6 Inspection Requirements
-8 Test Procedures, Checkout Manuals, or Programmed Tests
12.2.3.2 In some instances the reserved numbers in group three are followed by one or more alpha characters indicating a
series of checklists, workcards or supplements. The following alpha characters are authorized for use in Category 9:
CL - Checklists
TO 00-5-18
12-1
S - Operational Supplements
SS - Safety Supplements
WC - Workcards
12.2.3.3 If the TO number has four basic groups, the third group contains one or more numeric characters representing the
model, type or PN assigned to specific equipment or components. When this occurs the specific types of TOs are then
identified in group four.
12.2.4 Group Four. If the TO number has four basic groups, the fourth group identifies specific types of TOs described in
Paragraph 12.2.3.1, above.
12.3 EXAMPLES OF CATEGORY 9 NUMBERING PATTERNS.

CHAPTER 13
CATEGORY 10 - PHOTOGRAPHIC EQUIPMENT
13.1 GENERAL.
Category 10 contains twelve primary photographic systems. These systems are divided into equipment series and in some
instances further divided into equipment subseries within each equipment series. Therefore TO numbers in Category 10 use
both three and four groups for data identification. Numbering patterns for both groups are discussed in Paragraph 13.2.
13.1.1 Multiple Systems. TO data pertaining to more than one system is numbered in the category general series.
13.1.2 Multiple Equipment. Information pertaining to more than one equipment series within a system is numbered in the
system general series.
13.2 NUMBERING PATTERNS.
13.2.1 Group One. This group has three parts identifying the category, system and equipment series within each system.
13.2.1.1 Part one is always the numeric 10 identifying Category 10.
13.2.1.2 Part two is an alpha character that indicates the photographic equipment system, i.e., A - airborne cameras; B -
ground cameras; C - motion picture cameras; D - projection equipment; E -processing equipment; F - microfilm equipment;
G - photographic kits; H - interpretation and photogrammetric equipment; J - sensitized materials; K - radar assessing
equipment; L - photographic instrumentation equipment; and M - mobile photographic laboratories.
13.2.1.3 Part three contains one or more numeric characters identifying the equipment series within a system. These TO
numbering series are outlined in Paragraph 13.4.
13.2.2 Group Two. Since TO numbering patterns in Category 10 use both three and four basic groups, the identifiers in
group two are not constant. The following explains both numbering patterns:
13.2.2.1 If the TO number uses only three basic groups, group two will have one or more numeric characters representing
the model, type or PN assigned to specific components.
13.2.2.2 If the TO number contains four basic groups, the equipment series identified in group one, part three, has been
divided into equipment subseries. In this case group two identifies the equipment subseries with one or more numeric
characters and the model, type or PN identified in group three.
13.2.3 Group Three.
13.2.3.1 If a TO number has only three basic groups, the third group identifies the type of TO (see Appendix C for a
complete list of types of TOs). The following is a list of numbers reserved to identify specific types of TOs in Category 10:

CL - Checklists
S - Operational Supplements
SS - Safety Supplements
WC - Workcards
13.2.3.3 If the TO number has four basic groups, the third group contains one or more numeric characters representing
model, type or PN assigned to specific equipment or components. When this occurs the specific types of TOs are then
identified in group four.
13.2.4 Group Four. If the TO number has four basic groups, the fourth group identifies specific types of TOs described in
Paragraph 13.2.3.1.

CHAPTER 14
CATEGORY 11 - ARMAMENT EQUIPMENT
14.1 GENERAL.
Category 11 contains thirteen armament systems. These systems are divided into equipment series and most of the systems
are further divided into equipment subseries within each equipment series. Therefore, TO numbers in Category 11 use both
three and four basic groups for data identification. Numbering patterns for both groups are discussed in Paragraph 14.2.
NOTE
Legacy 11N TO numbering did not follow standard formatting patterns, previously numbered 11N TOs will not be
re-numbered solely to match the following numbering requirements.
14.1.1 Multiple Systems. TO data pertaining to more than one system is numbered in the category general series.
14.1.2 Multiple Equipment. Information relating to more than one equipment series within a system is numbered in the
system general series.
14.2 NUMBERING PATTERNS.
14.2.1 Group One. GROUP ONE. This group has three parts that identify the category, system and equipment series
within the system.
14.2.1.1 Part one is always the numeric 11 identifying Category 11.
14.2.1.2 Part two is an alpha character identifying the armament system, i.e., A - ammunition; B - bombing systems and
equipment; C -chemical warfare agents, explosives, gases and weapons; D - decontamination, impregnating and protective
equipment; E - biological warfare agents; F - fire control systems and equipment; G - guidance and control systems and
equipment; H - hazard detecting equipment; K - guided glide weapons; L - launchers and equipment; N - nuclear weapons
and equipment; P - egress systems, explosive devices and equipment; R - missile re entry vehicles and equipment; and W -
weapons and equipment. Only two of the 13 systems in Category 11 have associated equipment identified. These two
systems are: launchers and equipment, and weapons and equipment. The associated equipment is identified by adding the
alpha A immediately following the armament system identifier, i.e., LA and WA.
14.2.1.3 Part three contains one or more numeric characters identifying an equipment series within the system. The TO
numbering series are outlined in Paragraph 14.4.
14.2.2 Group Two. TO numbering patterns in Category 11 use both three and four basic groups; therefore, the identifiers
in group two are not constant. The following describes both numbering patterns:
14.2.2.1 If the TO number uses only three basic groups, group two will have one or more numeric characters representing
the model, type or PN assigned to specific equipment.
14.2.2.2 If the TO number contains four basic groups, the equipment series identified in part three of group one has been
further divided into equipment subseries. In this case group two identifies the equipment subseries with one or more numeric
characters and the model, type or PN is identified in group three.
14.2.2.3 Bombing systems and fire control systems with JETDS (Joint Electronics Type Designator System) numbers or
Air Force type numbers are numbered in the 11B1 and 11F1 series respectively. The type designator, in this instance, is used
to form group two of the TO number. (See examples in Paragraph 4.3.4 and Paragraph 4.3.5.)
14.2.3 Group Three.
TO 00-5-18
14-1
14.2.3.1 If a TO number has only three basic groups, the third group identifies the type of TO (see Appendix C for a
complete list of types of TOs). The following is a list of numbers reserved to identify specific types of TOs in Category 11:
-01 List of Applicable Publications (LOAP)
-06 Work Unit Code Manuals
-07 thru -09 Reserved
-1 Operating Instructions
-2 Service or Maintenance Manuals
-3 Depot Maintenance or Overhaul Instructions
-4 Illustrated Parts Breakdown
-6 Inspection Requirements
-7 Storage, Installation and Installation Test Procedures
-8 Test Procedures, Checkout Manuals, or Programmed Tests
14.2.3.2 In some instances the reserved numbers in group three are followed by one or more alpha characters indicating a
series of checklists, workcards, supplements or other media. The following alpha characters are authorized for use in
Category 11:
CL - Checklists
S - Operational Supplements
SS - Safety Supplements
WC - Workcards
14.2.3.3 If the TO number has four basic groups, the third group contains one or more numeric characters representing
model, type or PN assigned to specific component assemblies.
14.2.4 Group Four. If the TO number has four basic groups, the fourth group identifies specific types of TOs described in
Paragraph 14.2.3.1.
14.3 EXAMPLES OF CATEGORY 11 NUMBERING PATTERNS.

CHAPTER 15
CATEGORY 12 - AIRBORNE ELECTRONIC EQUIPMENT
15.1 GENERAL.
Much of the equipment covered by TOs in this category is identified under the Joint Electronics Type Designation System
(JETDS). The JETDS, formerly known as the AN nomenclature system, is described in MIL-STD-196.
15.1.1 Primary Systems. Category 12 contains seven primary airborne electronic equipment systems. These systems are
divided into equipment series and further divided into equipment subseries within each equipment series. TO numbers in
Category 12 use both three and four basic groups for data identification. Numbering patterns for both groups are discussed
in Paragraph 15.2.
15.1.2 Multiple Systems. TO data pertaining to more than one system is numbered in the category general series.
15.1.3 Multiple Equipment. Information relating to more than one equipment series is numbered in the system general
series.
15.1.4 JETDS TOs. General TOs for JETDS equipment are described in Paragraph 1.19.
15.2 NUMBERING PATTERNS.
15.2.1 Group One. This group has three parts identifying the category, system and equipment series within the system.
15.2.1.1 Part one is always the numeric 12 identifying Category 12.
15.2.1.2 Part two is an alpha character identifying the electronic system, i.e., A - synchros and resolvers; C - crystal units;
M - meteorological equipment; P - radar equipment; R - radio equipment; and S - special electronic equipment.
15.2.1.3 Part three contains one or more numeric characters identifying an equipment series within a system. The TO
numbering series is outlined in Paragraph 15.4.
15.2.2 Group Two. TO numbering patterns in Category 12 use both three and four basic groups; therefore, the identifiers
in group two are not constant. The following explains both numbering patterns:

EQUIPMENT
16.1 GENERAL.
Category 13 contains five primary systems. These systems are divided into equipment series and most of the systems are
further divided into equipment subseries within each equipment series. Therefore TO numbers in Category 13 use both three
and four basic groups for data identification. Numbering patterns for both groups are discussed in Paragraph 16.2.
16.1.1 Multiple Systems. TO data pertaining to more than one system is numbered in the category general series.
16.1.2 Multiple Equipment. Information relating to more than one equipment series within a system is numbered in the
system general series.
16.2 NUMBERING PATTERNS.
16.2.1 Group One. This group has three parts identifying the category, system and equipment series within the system.
16.2.1.1 Part one is always the numeric 13 identifying Category 13.
16.2.1.2 Part two is an alpha character identifying the system, i.e., A - aircraft furnishings; B - in-flight feeding equipment;
C - cargo loading, tiedown and aerial delivery equipment; D - recovery equipment; and F - aircraft fire detection and
extinguishing equipment.
16.2.1.3 Part three contains one or more numeric characters identifying an equipment series within a system. The TO
numbering series is outlined in Paragraph 16.4.
16.2.2 Group Two. TO numbering patterns in Category 13 use both three and four basic groups; therefore, the identifiers
in group two are not constant. The following describes both numbering patterns:
16.2.2.1 If the TO number uses only three basic groups, group two has one or more numeric characters representing the
model, type or PN assigned to specific components.
16.2.2.2 If the TO number contains four basic groups, the equipment series identified in part three of group one has been
further divided into equipment subseries. In this case group two identifies the equipment subseries with one or more numeric
characters and the model, type or PN is identified in group three.
16.2.3 Group Three.
16.2.3.1 If a TO number has only three basic groups, the third group identifies the type of TO (see Appendix C for a
complete list of types of TOs). The following is a list of numbers reserved to identify specific types of TOs in Category 13:

18.1 GENERAL.
Category 15 contains five systems. These systems are divided into equipment series and most of the systems are further
divided into equipment subseries within each equipment series. Therefore, TO numbers in Category 15 use both three and
four basic groups for data identification. Numbering patterns for both groups are discussed in Paragraph 18.2.
18.1.1 Multiple Systems. TO data pertaining to more than one system is numbered in the category general series.
18.1.2 Multiple Equipment. Information relating to more than one equipment series within a system is numbered in the
system general series.
18.2 NUMBERING PATTERNS.
18.2.1 Group One. This group has three parts which identify the category, system, and equipment series within a system.
18.2.1.1 Part one is always the numeric 15 identifying Category 15.
18.2.1.2 Part two is an alpha character identifying one of five systems, i.e., A - air conditioning and pressurizing equip-
ment; E - ice eliminating equipment; H - cabin heating equipment; M - missile temperature control equipment; and X -

CHAPTER 19
CATEGORY 16 - AIRBORNE MECHANICAL EQUIPMENT
19.1 GENERAL.
Category 16 contains seven mechanical systems. These systems are divided into equipment series and most of the systems
are further divided into equipment subseries within each equipment series. Therefore TO numbers in Category 16 use both
three and four basic groups for data identification. Numbering patterns for both forms are discussed in Paragraph 19.2.
19.1.1 Multiple Systems. TO data pertaining to more than one system is numbered in the category general series.
19.1.2 Multiple Equipment. Information relating to more than one equipment series within a system is numbered in the
system general series.
19.2 NUMBERING PATTERNS.
19.2.1 Group One. This group has three parts identifying the category, system, and the equipment series within the
system.
19.2.1.1 Part one is always the numeric 16 identifying Category 16.
19.2.1.2 Part two is an alpha character identifying the mechanical systems, i.e., A - actuators; C - control units; G - gear
box, drive and screwjack assemblies; K - release mechanisms; L - lock and latching mechanisms; R - regulating mecha-
nisms; and W - structural components. Associated equipment for these systems are identified by adding the alpha A imme-
diately following the mechanical system identifier, e.g., GA.
19.2.1.3 Part three contains one or more numeric characters identifying an equipment series within a system. The TO
numbering series are outlined in Paragraph 19.4.
19.2.2 Group Two. TO numbering patterns in Category 16 use both three and four basic groups; therefore, the identifiers
in group two are not constant. The following describes both numbering patterns:
19.2.2.1 If the TO number uses only three basic groups, group two will have one or more numeric characters representing
the model, type or PN assigned to specific equipment.
19.2.2.2 If the TO number contains four basic groups, the equipment series identified in part three of group one has been
further divided into equipment subseries. In this case, group two identifies the equipment subseries with one or more
numeric characters and the model, type or PN is identified in group three.
19.2.3 Group Three.
19.2.3.1 If a TO number has only three basic groups, the third group identifies the type of TO (see Appendix C for a
complete list of types of TOs). The following is a list of numbers reserved to identify specific types of TOs in Category 16:
-1 Operating Instructions
-2 Service or Maintenance Manuals
-3 Depot Maintenance or Overhaul Instructions
-4 Illustrated Parts Breakdown
-7 Installation Instructions
19.2.3.2 In some instances the reserved numbers in group three are followed by one or more alpha characters indicating a
series of checklists, workcards or supplements. The following alpha characters are authorized for use in Category 16:
CL - Checklists
TO 00-5-18
19-1
S - Operational Supplements
SS - Safety Supplements
WC - Workcards
19.2.3.3 If the TO number has four basic groups, the third group contains one or more numeric characters representing
model, type or PN assigned to specific components.
19.2.4 Group Four. If the TO number has four basic groups, the fourth group identifies specific types of TOs described in
Paragraph 19.2.3.1, above.
19.3 EXAMPLES OF CATEGORY 16 NUMBERING PATTERNS.

CHAPTER 20
CATEGORY 21 - GUIDED MISSILES
20.1 GENERAL.
Technical data numbered in the missile category includes operations manuals, organization (on site) maintenance instruc-
tions, inspection requirements, overhaul instructions and specified procedures relating to missiles. TO numbers incorporate
the missile type or mission, model and production series, which groups types of missile data accordingly.
20.1.1 Multiple Systems. Technical information pertaining to more than one type of missile is numbered in the category
general series. Since the data pertains to more than one type of missile, TO numbers assigned in the category general series
do not reflect the missile type, model or production series. A manual entitled, “Plating Procedures for the AIM-4 and the
LGM-30” would be numbered as follows:
21M-1-107
21 Category 21
M Missile
1 Category General Series
107 Serialized Manual Number
20.1.2 Multiple Models. TOs pertaining to more than one model of a specific type of missile are numbered in the general
series of that missile type. An operational manual relating to the AIM-4 and the AIM-26 would be numbered as follows:
21M-AIM-101
21 Category 21
M Missile
AIM Air Launched, Intercept Aerial, Missile
101 Serialized Manual Number
20.1.3 Multiple Production Series. Technical information pertaining to more than one production series of a missile
model is numbered in the first production series. A field checkout instruction for the AIM-4A, AIM-4D and AIM-4G would
be numbered in the “A” production series.
20.1.4 Missle Timeframe. TOs for earlier guided missiles are numbered as described in Paragraph 20.2 and Paragraph
20.3. TOs for the M-X and later guided missile systems are numbered as described in Paragraph 20.4.
20.2 NUMBERING PATTERNS.
20.2.1 Group One. In Category 21, the first group has only two parts, identifying the category, and a designator indicat-
ing missiles.
20.2.1.1 Part one is always the numeric 21 identifying Category 21.
20.2.1.2 Part two is always the alpha M identifying missiles.
20.2.2 Group Two. This group can have either two or three parts. If two parts are used, the missile type and model only
are identified. This normally means the TO contains general information pertaining to all production series of a specific
missile type and model. In most cases, three parts are used in group three, indicating the missile type, model and production
series.
TO 00-5-18
20-1
20.2.2.1 Part one is composed of three alpha characters. The first alpha character identifies the missile launch environ-
ment; the second indicates the basic mission of the missile; and the third describes the missile vehicle type. The following
listing outlines these alpha designators as established by AFI 16-401 Designated and Naming Defense Military Aerospace
Vehicles:
LAUNCH ENVIRONMENT
A - Air
B - Multiple
C - Coffin
F - Individual
G - Runway
H - Silo Stored
L - Silo Launched
M - Mobile
P - Soft Pad
R - Ship
U - Underwater
BASIC MISSION
D - Decoy
E - Special Electronic Installation
G - Surface Attack
I - Intercept Aerial
Q - Drone
T - Training
U - Underwater Attack
W - Weather
VEHICLE TYPE
M - Guided Missile/Drone
20.2.2.2 Part two contains one or more numeric characters identifying the missile model number.
20.2.2.3 Part three is an alpha character indicating the missile production series. The first production series of a particular
missile is designated with the alpha A, the second with the alpha B and continuing through the alphabet as required.
20.2.2.4 It is possible that a fourth part may be required for group two in order to identify a missile production configu-
ration. If this becomes a requirement, the production configuration identifier (PCI) will be an alpha character immediately
following the production series identifier. The alpha A is reserved to indicate USAF missile configurations and the remainder
of the alphabet will be used for those configurations produced for foreign countries. Although the alpha A is reserved to
identify USAF missile configurations, no specific alpha character will be associated with or reserved for missile configura-
tions for a particular foreign country.
20.2.3 Group Three. In Category 21, the third group primarily identifies the type of inspection, instruction, or procedure.
This can be accomplished by either one or two parts.
20.2.3.1 Part one consists of one or more numeric characters reserved to indicate a specific type of TO (see Appendix C
for a complete list of types of TOs). The following is a list of reserved numbers authorized for use in Category 21:
-01 List of Applicable Publications (LOAP)
-06 Work Unit Code Manuals
-07 thru -09 Reserved
-1 Operating Instructions
-2 Organizational Maintenance Manuals
TO 00-5-18

-18 Field Maintenance and Materials Manuals
-21 Missile Inventory Record Master Guides
-22 Control Manuals
-23 Corrosion Control Manuals
-26 Non-Destructive Inspection Manuals
-27 Calibration and Measurement Manuals
-33 Contractor Maintenance Data
20.2.3.2 Part two. In some instances some of the reserved numbers listed in part one, above, are followed by one or more
alpha characters indicating a series of checklists, workcards, supplements, and other media. The following lists the alpha
characters authorized for use in Category 21:
CL - Checklist
S - Operational Supplements
SS - Safety Supplements
WC - Workcards
WS - Worksheets
20.2.4 Group Four. This group consists of one or more numeric characters identifying sections of a sectionalized manual
or indicating the series number of specific TO data in a series of inspections, supplements, or functions.
20.2.5 Group Five. When required, this group contains one or more numeric characters indicating a further sectionaliza-
tion or serialization of a TO.
20.3 EXAMPLES OF CATEGORY 21 NUMBERING PATTERNS.
20.3.1 Example One. A work unit code manual for the AIM-9E missile:
21M-AIM9E-06
21 Category 21
M Missiles

20.3.3 Example Three. Structural repair manual for the LGM-30A missile:
21M-LGM30A-3
21 Category 21
M Missiles
LGM Launched Ground Missiles
30 Missile Model Number
A Product Series
3 Number Reserved for Structural Repair Manuals
20.4 SHORTENED NUMBERING FOR MISSILE TECHNICAL ORDER MANUALS.
To eliminate redundancy, TO numbers for future missiles will be shortened by eliminating the M in category designator 21M
and by eliminating the M in model designators such as LGM. These codes are redundant, since only missile TOs appear in
Category 21.
20.4.1 Shortening TO Numbers. Using shortened TO numbers will be effective with the LGM-118A and future missile
designs. Use of the former numbering practice will continue for earlier designated missiles. Existing TOs in Category 21 will
not be renumbered for the sole purpose of shortening the TO numbers.
20.4.2 Example One. The following is an example of this method applied to an organizational maintenance instruction
for launch facility and launch control facility environmental control system for the LGM-118A missile:

CHAPTER 21
CATEGORY 22 - AEROSPACE VEHICLES
21.1 GENERAL.
TO data numbered in this category identifies operational, organizational maintenance, inspection and procedures related to
aerospace vehicles and systems. Aerospace vehicles are either manned or unmanned flight vehicles operating in the atmo-
sphere or space environment. TO numbers incorporate the aerospace vehicle type and model or the aerospace system which
identifies family groups according to mission or function.
21.1.1 Multiple Aerospace Vehicles. Information pertaining to more than one aerospace vehicle is numbered in the

CHAPTER 22
CATEGORY 31 - GROUND ELECTRONIC EQUIPMENT
22.1 GENERAL.
Much of the equipment covered by TOs in this category is identified under the Joint Electronics Type Designation System
(JETDS). The JETDS, which was formerly known as the AN Nomenclature System, is described in MIL-STD-196.
22.1.1 Primary Systems. Category 31 contains seven primary ground electronic equipment systems. These systems are
divided into equipment series; some are further divided into equipment subseries within the equipment series. TO numbers
in Category 31 use both three and four basic groups for data identification. Numbering patterns for both forms are discussed
in Paragraph 22.2.
22.1.2 Multiple Systems. TO data pertaining to more than one system is numbered in the category general series.
22.1.3 Multiple Equipment. Information relating to more than one equipment series is numbered in the system general
series.
22.1.4 JETDS TOs. General TOs for JETDS equipment are described in Paragraph 1.19.
22.2 NUMBERING PATTERNS.
22.2.1 Group One. This group has three parts identifying the category, system and equipment series within a system.
22.2.1.1 Part one is always the numeric 31 identifying Category 31.
22.2.1.2 Part two is an alpha character identifying the electronic equipment system, i.e., M - meteorological equipment; P
- radar equipment; R - radio equipment; S - special electronic equipment; W - wire fixed electronic equipment; X - missile
ground operational equipment; and Z - systems and site equipment. Missile ground operational equipment is the only system
in Category 31 that has associated equipment. Its associated equipment is identified by XA.
NOTE
Although numerous TOs are currently numbered in the 31X and 31XA series, these series will not be used for
numbering new TOs. Future TOs for missile ground operational equipment will be numbered in appropriate
functional equipment systems of Category 31.
22.2.1.3 Part three contains one or more numeric characters identifying an equipment series within a system. The TO
numbering series is outlined in Paragraph 22.4.
22.2.2 Group Two. The several numbering patterns currently used in Category 31 are most conspicuous in the group two
numbering configurations. Numbering patterns are as follows:
22.2.2.1 This paragraph covers numbering patterns for 31M, 31P, 31R, 31S and 31W systems. The numbering patterns use
both three and four basic groups; therefore, the identifiers in group two are not constant.
22.2.2.1.1 If the equipment types are JETDS nomenclatured, three basic groups are used in the TO number. The numeric
2 followed immediately by an alphameric JETDS nomenclature comprises group two.
22.2.2.1.2 If the equipment types are Signal Corps nomenclatured, three basic groups are used in the TO number. The
numeric 3 followed immediately by an alphameric Signal Corps nomenclature comprises group two.
22.2.2.1.3 If the equipment types are Air Force nomenclatured, three basic groups are used in the TO number. The
numeric 5 followed immediately by an alphameric AF nomenclature comprises group two.
TO 00-5-18
22-1
22.2.2.1.4 If the equipment types are commercially nomenclatured (not JETDS, Signal Corps, or AF), four basic groups
are used in the TO number. The numeric 4 is the only character in group two.
22.2.2.2 This paragraph covers numbering patterns for the 31X system which uses both three and four basic groups.
22.2.2.2.1 The numbering pattern for basic equipment TOs in the 31X System uses four basic groups. In this case one or
more numeric characters in group two identify the equipment subseries.
22.2.2.2.2 The numbering pattern for associated equipment TOs (indicator 31XA) uses only three basic groups. In this
case one or more numeric characters in group two represent the model, type or PN assigned to specific equipment.
22.2.2.3 The numbering pattern for 31Z series TOs uses three basic groups. Group two, with one or more numeric
characters, identifies AFCS (formerly GEEIA) Engineering-Installation Standards or a specific system, site, facility or spe-
cial project. The type of TO is identified in group three as described in Paragraph 22.2.3.1, below.
22.2.3 Group Three.
22.2.3.1 If a TO number has only three basic groups, the third group identifies the type of TO (see Appendix C for a
complete list of types of TOs). The following is a list of numbers reserved to identify specific types of TOs in Category 31:
-01 List of Applicable Publications (LOAP)
-06 Work Unit Code Manuals
-07 thru -09 Reserved
-1 Operating Instructions
-2 Service or Maintenance Instructions
-3 Depot Maintenance or Overhaul Instructions
-4 Illustrated Parts Breakdown
-5 Command Manuals
-6 Inspection Requirements
-7 Installation Instructions and Installation Test Procedures
-8 Test Procedures, Checkout Manuals, or Programmed Tests
-9 Alignment Instructions
22.2.3.2 In some instances the reserved numbers in group three are followed by one or more alpha characters indicating a
series of checklists, workcards, supplements or other media. The following alpha characters are authorized for use in
Category 31:
CL - Checklists
S - Operational Supplements
SS - Safety Supplements
WC - Workcards
22.2.3.3 If the TO number has four basic groups, the third group contains one or more numeric characters representing
model, type or PN assigned to specific equipment or components. When this occurs the specific type of TO is then identified
in group four.
22.2.4 Group Four. If the TO number has four basic groups, the fourth group identifies specific types of TOs described in
Paragraph 22.2.3.1.

CHAPTER 23
CATEGORY 32 - STANDARD AND SPECIAL TOOLS
23.1 GENERAL.
Category 32 contains two types of tool systems. These systems are divided into equipment series and both of the systems are
further divided into equipment subseries within each equipment series. Therefore TO numbers in Category 32 use both three
and four basic groups for data identification. Numbering patterns for both forms are discussed in Paragraph 23.2.
23.1.1 Multiple Systems. TO data pertaining to more than one system is numbered in the category general series.
23.1.2 Multiple Equipment. Information relating to more than one equipment series within a system is numbered in the
system general series.
23.2 NUMBERING PATTERNS.
23.2.1 Group One. This group has three parts identifying the category, system and equipment series within a system.
23.2.1.1 Part one is always the numeric 32, identifying Category 32.
23.2.1.2 Part two is an alpha character identifying the system, i.e., A - special tools and B - standard tools.
23.2.1.3 Part three contains one or more numeric characters identifying an equipment series within a system. The TO
numbering series is outlined in Paragraph 23.4.
23.2.2 Group Two. TO numbering patterns in Category 32 use both three and four basic groups; therefore, the identifiers
in group two are not constant. The following describes both numbering patterns:
23.2.2.1 If the TO number uses only three basic groups, group two has one or more numeric characters representing the
model, type or PN assigned to specific equipment.
23.2.2.2 If the TO number contains four basic groups, the equipment series identified in part three of group one has been
further divided into equipment subseries. In this case, group two identifies the equipment subseries with one or more
numeric characters and the model, type or PN is identified in group three.
23.2.3 Group Three.
23.2.3.1 If a TO number has only three basic groups, the third group identifies the type of TO (see Appendix C for a
complete list of types of TOs). The following is a list of numbers reserved to identify specific types of TOs in Category 32:
-1 Operating Instructions
-2 Service or Maintenance Manuals
-3 Depot Maintenance or Overhaul Instructions
-4 Illustrated Parts Breakdown
-7 Installation Instructions
23.2.3.2 In some instances the reserved numbers in group three are followed by one or more alpha characters indicating a
series of checklists, workcards or supplements. The following alpha characters are authorized for use in Category 32:
CL - Checklists
S - Operational Supplements
SS - Safety Supplements
WC - Workcards
TO 00-5-18
23-1
23.2.3.3 If the TO number has four basic groups, the third group contains one or more numeric characters representing
model, type or PN assigned to specific components.
23.2.4 Group Four. If the TO number has four basic groups, the fourth group identifies specific types of TOs described in
Paragraph 23.2.3.1, above.

CHAPTER 24
CATEGORY 33 - TEST EQUIPMENT
24.1 GENERAL.
This category contains testers, test equipment and test interface equipment. Test procedures, test control and programmed
test TOs are numbered with related equipment identified in the various airborne and ground component categories.
24.1.1 Multiple Series. Category 33 contains five test equipment systems. These systems are divided into equipment
series and most of the systems are further divided into equipment subseries within each equipment series. Therefore TO
numbers in Category 33 use both three and four basic groups for data identification. Numbering patterns for both forms are
discussed in Paragraph 24.2.
24.1.2 Multiple Sytems. TO data pertaining to more than one system is numbered in the category general series.
24.1.3 Multiple Equipment. Information relating to more than one equipment series within a system is numbered in the
system general series.
24.2 NUMBERING PATTERNS.
24.2.1 Group One. This group has three parts that identify the category, system and equipment series within a system.
24.2.1.1 Part one is always the numeric 33 identifying Category 33.
24.2.1.2 Part two is an alpha character identifying one of five aerospace systems, i.e., A - general purpose test equipment;
B - inspection test equipment; C - laboratory test equipment; D - special purpose test equipment; and K - calibration
procedures. Only 33A and 33D systems have associated equipment TOs. Associated equipment for these systems is identi-
fied by adding the alpha A immediately following the system identifier, i.e., AA or DA.
24.2.1.3 Part three contains one or more numeric characters that identify an equipment series within a system. The TO
numbering series is outlined in Paragraph 24.4.
24.2.2 Group Two. TO numbering patterns in Category 33 use both three and four basic groups; therefore, the identifiers
in group two are not constant. The following describes both numbering patterns:
24.2.2.1 If the TO number uses only three basic groups, group two will have one or more numeric characters representing
the model, type or PN assigned to specific components.
24.2.2.2 If the TO number contains four basic groups, the equipment series identified in part three of group one has been
further divided into equipment subseries. In this case, group two identifies the equipment subseries with one or more
numeric characters and the model, type or PN is identified in group three.
24.2.3 Group Three.
24.2.3.1 If a TO number has only three basic groups, the third group identifies the type of TO (see Appendix C for a
complete list of types of TOs). The following is a list of numbers reserved to identify specific types of TOs in Category 33:
-1 Operating Instructions
-2 Service or Maintenance Manuals
-3 Depot Maintenance Manuals
-4 Illustrated Parts Breakdown
-5 Depot Calibration
-6 Inspection Requirements
-7 Installation Instructions and Installation Test Procedures
TO 00-5-18
24-1
-8 Test Procedures, Checkout Manuals, or Programmed Tests
-9 Alignment Instructions
24.2.3.2 In some instances the reserved numbers are followed by one or more alpha characters indicating a series of
checklists, workcards, supplements or other media. The following alpha characters are authorized for use in Category 33:
CL - Checklists
S - Operational Supplements
SS - Safety Supplements
VS - Visual Slide
WC - Workcards
24.2.3.3 If the TO number has four basic groups, the third group contains one or more numeric characters representing the
model, type or PNs assigned to specific components.
24.2.4 Group Four. If the TO number has four basic groups, the fourth group identifies specific types of TOs described in
Paragraph 24.2.3.1, above.

CATEGORY 34 - SHOP MACHINERY AND SHOP SUPPORT EQUIPMENT
25.1 GENERAL.
Category 34 contains five shop machinery and shop support equipment systems. These systems are divided into equipment
series and most of the systems are further divided into equipment subseries within each equipment series. Therefore, TO
numbers in Category 34 use both three and four basic groups for data identification. Numbering patterns for both forms are
discussed in Paragraph 25.2.
25.1.1 Multiple Systems. TO data pertaining to more than one system is numbered in the category general series.
25.1.2 Multiple Equipment. Information relating to more than one equipment series within a system is numbered in the
system general series.
25.2 NUMBERING PATTERNS.
25.2.1 Group One. This group has three parts identifying the category, system and equipment series within a system.
25.2.1.1 Part one is always the numeric 34 identifying Category 34.
25.2.1.2 Part two is an alpha character identifying the shop machinery systems, i.e., C - cutting machines; F - finishing
machines; G - forming machines; W - welding and heat treating equipment; and Y - shop support equipment.
25.2.1.3 Part three contains one or more numeric characters identifying an equipment series within a system. The TO
numbering series are outlined in Paragraph 25.4.
25.2.2 Group Two. TO numbering patterns in Category 34 use both three and four basic groups; therefore, the identifiers
in group two are not constant. The following describes both numbering patterns:
25.2.2.1 If the TO number uses only three basic groups, group two will have one or more numeric characters representing
the model, type or PN assigned to specific components.
25.2.2.2 If the TO number contains four basic groups, the equipment series identified in part three of group one has been
further divided into equipment subseries. In this case, group two identifies the equipment subseries with one or more
numeric characters and the model, type or PN is identified in group three.
25.2.3 Group Three.
25.2.3.1 If a TO number has only three basic groups, the third group identifies the type of TO (see Appendix C for a
complete list of types of TOs). The following is a list of numbers reserved to identify specific types of TOs in Category 34:
-1 Operating Instructions
-2 Service or Maintenance Manuals
-3 Depot Maintenance or Overhaul Instructions
-4 Illustrated Parts Breakdown
-6 Inspection Requirements
-7 Installation Instructions and Installation Test Procedures
-8 Test Procedures, Checkout Manuals, or Programmed Tests
TO 00-5-18
25-1
25.2.3.2 In some instances the reserved numbers in group three are followed by one or more alpha characters indicating a
series of checklists, workcards, supplements or other media. The following alpha characters are authorized for use in
Category 34:
CL - Checklists
S - Operational Supplements
SS - Safety Supplements
WC - Workcards
25.2.3.3 If the TO number has four basic groups, the third group contains one or more numeric characters representing
model, type or PN assigned to specific components.
25.2.4 Group Four. When the TO number has four basic groups, the fourth group identifies specific types of TOs
described in Paragraph 25.2.3.1, above.

CATEGORY 35 - GROUND HANDLING, SUPPORT, AIR AND MISSILE BASE
OPERATING EQUIPMENT
26.1 GENERAL.
Category 35 contains eight ground handling, support and operating systems. These systems are divided into equipment series
and most of the systems are further divided into equipment subseries within each equipment series. Therefore TO numbers
in Category 35 use both three and four basic groups for data identification. Numbering patterns for both forms are discussed
in Paragraph 26.2.
26.1.1 Multiple Systems. TO data pertaining to more than one system is numbered in the category general series.
26.1.2 Multiple Equipment. Information relating to more than one equipment series within a system is numbered in the
system general series.
26.2 NUMBERING PATTERNS.
26.2.1 Group One. This group has three parts identifying the category, system and equipment series within a system.
26.2.1.1 Part one is always the numeric 35 identifying category 35.
26.2.1.2 Part two is an alpha character identifying the ground handling, support or operating system, i.e., A - aircraft
maintenance and inspection equipment; B - aircraft handling and weighing equipment; C - electric power supplies; D -
loading and servicing equipment; E - air base utility equipment; G - aircraft ground support equipment; and M - missile
erection and launching equipment. Associated equipment for these systems are identified by adding the alpha A immediately
following the system identifier, e.g., AA, and CA.
26.2.1.3 Part three contains one or more numeric characters identifying an equipment series within a system. The TO
numbering series are outlined in Paragraph 26.4.
26.2.2 Group Two. TO numbering patterns in Category 35 use both three and four basic groups; therefore, the identifiers
in group two are not constant. The following describes both numbering patterns.
26.2.2.1 If the TO number uses only three basic groups, group two will have one or more numeric characters representing
the model, type or PN assigned to specific components.
26.2.2.2 If the TO number contains four basic groups, the equipment series identified in part three of group one has been
further divided into equipment subseries. In this case, group two identifies the equipment subseries with one or more
numeric characters and the model, type or PN is identified in group three.
26.2.3 Group Three.
26.2.3.1 When a TO number has only three basic groups, the third group identifies the type of TO (see Appendix C for a
complete list of types of TOs). The following is a list of numbers reserved to identify specific types of TOs in Category 35:
-01 List of Applicable Publications (LOAP)
-06 Work Unit Code Manuals

26.2.3.2 In some instances the reserved numbers in group three are followed by one or more alpha characters indicating a
series of checklists, workcards or supplements. The following alpha characters are authorized for use in Category 35:
CL - Checklists
S - Operational Supplements
SS - Safety Supplements
WC - Workcards
26.2.3.3 If the TO number has four basic groups, the third group contains one or more numeric characters representing the
model, type or PN assigned to specific components.
26.2.4 Group Four. If the TO number has four basic groups, the fourth group either identifies specific types of TOs
described in Paragraph 26.2.3.1, or it identifies a sequence number when alpha characters were used in group three as
described in Paragraph 26.2.3.2. Sequence numbers are described in Paragraph 1.6.2 through Paragraph 1.6.6.

CHAPTER 27
CATEGORY 36 - VEHICLES, CONSTRUCTION AND MATERIAL-HANDLING
EQUIPMENT
27.1 GENERAL.
Category 36 contains six systems. These systems are divided into equipment series and most of the systems are further
divided into equipment subseries within each equipment series. Therefore, TO numbers in Category 36 use both three and
four basic groups for data identification. Numbering patterns for both forms are discussed in Paragraph 27.2.
27.1.1 Multiple Systems. TO data pertaining to more than one system is numbered in the category general series.
27.1.2 Multiple Equipment. Information relating to more than one equipment series within a system is numbered in the
system general series.
27.2 NUMBERING PATTERNS.
27.2.1 Group One. This group has three parts identifying the category, system and equipment series within a system.
27.2.1.1 Part one is always the numeric 36 identifying Category 36.
27.2.1.2 Part two is an alpha character identifying one of six systems; i.e., A - vehicles; C - construction equipment; G
-gas generating equipment; M - materials handling equipment; R - ordnance equipment; and Y - vehicle, construction and
material-handling equipment. Associated equipment for these systems are identified by adding the alpha A immediately
following the system identifier, e.g., MA.
27.2.1.3 Part three contains one or more numeric characters identifying an equipment series within a system. The TO
numbering series are outlined in Paragraph 27.4.
27.2.2 Group Two. TO numbering patterns in Category 36 use both three and four basic groups; therefore, the identifiers
in group two are not constant. The following describes both numbering patterns.
27.2.2.1 If the TO number uses only three basic groups, group two will have one or more numeric characters representing
the model, type or PN assigned to specific components.
27.2.2.2 If the TO number contains four basic groups, the equipment series identified in part three of group one has been
further divided into equipment subseries. In this case, group two identifies the equipment subseries with one or more
numeric characters and the model, type or PN is identified in group three.
27.2.3 Group Three.
27.2.3.1 If a TO number has only three basic groups, the third group identifies the type of TO (see Appendix C for a
complete list of types of TOs). The following is a list of numbers reserved to identify specific types of TOs in Category 36:
-1 Operating Instructions
-2 Service or Maintenance Manuals
-3 Depot Maintenance or Overhaul Instructions
-4 Illustrated Parts Breakdown
-5 DCSC Technical Maintenance Standards
-6 Inspection Requirements
-7 Installation Instructions
TO 00-5-18
27-1
27.2.3.2 In some instances the reserved numbers in group three are followed by one or more alpha characters indicating a
series of checklists, workcards, supplements or other media. The following alpha characters are authorized for use in
Category 36:
CL - Checklists
LC - Lubrication Charts
S - Operational Supplements

CHAPTER 28
CATEGORY 37 - FUEL-, OIL- AND PROPELLANT-HANDLING EQUIPMENT
28.1 GENERAL.
Category 37 contains three fuel-, oil-, and propellant-handling systems. These systems are divided into equipment series and
most of the systems are further divided into equipment subseries within each equipment series. Therefore TO numbers in
Category 37 use both three and four basic groups for data identification. Numbering patterns for both forms are discussed in
Paragraph 28.2.
28.1.1 Multiple Systems. TO data pertaining to more than one system is numbered in the category general series.
28.1.2 Multiple Equipment. Information relating to more than one equipment series within a system is numbered in the
system general series.
28.2 NUMBERING PATTERNS.
28.2.1 Group One. This group has three parts identifying the category, system and equipment series within the system.
28.2.1.1 Part one is always the numeric 37 identifying Category 37.
28.2.1.2 Part two is an alpha character identifying the oil-, fuel-, and propellant-handling systems, i.e., A - fuel and oil
handling equipment; B - aircraft propellant systems; and C - propellant storage and handling equipment. Associated equip-
ment for these systems is identified by adding the alpha A immediately following the system identifier, e.g., CA.
28.2.1.3 Part three contains one or more numeric characters identifying an equipment series within a system. The TO
numbering series are outlined in Paragraph 28.4.
28.2.2 Group Two. TO numbering patterns in Category 37 use both three and four basic groups; therefore, the identifiers
in group two are not constant. The following describes both numbering patterns:
28.2.2.1 If the TO number uses only three basic groups, group two uses one or more numeric characters representing the
model, type or PN assigned to specific components.
28.2.2.2 If the TO number contains four basic groups, the equipment series identified in part three of group one has been
further divided into equipment subseries. In this case, group two identifies the equipment subseries with one or more
numeric characters and the model, type or PN is identified in group three.
28.2.3 Group Three.
28.2.3.1 If a TO number has only three basic groups, the third group identifies the type of TO (see Appendix C for a
complete list of types of TOs). The following is a list of numbers reserved to identify specific types of TOs in Category 37:
-1 Operating Instructions
-2 Service or Maintenance Manuals
-3 Depot Maintenance or Overhaul Instructions
-4 Illustrated Parts Breakdown
-6 Inspection Requirements
-7 Installation Instructions
TO 00-5-18
28-1
28.2.3.2 In some instances the reserved numbers in group three are followed by one or more alpha characters indicating a
series of checklists, workcards, supplements or other media. The following alpha characters are authorized for use in
Category 37:
CL - Checklists
S - Operational Supplements
SS - Safety Supplements
WC - Workcards
28.2.3.3 If the TO number has four basic groups, the third group contains one or more numeric characters representing
model, type or PN assigned to specific components.
28.2.4 Group Four. If the TO number has four basic groups, the fourth group identifies specific types of TOs described in
Paragraph 28.2.3.1, above.

FUELS, GASES, LUBRICANTS, CHEMICALS AND MATERIALS
33.1 GENERAL.
Category 42 contains seven systems divided into equipment or material series. The series, in some instances, are further
divided into material types. TO numbers in Category 42 use both three and four basic groups for data identification. The
numbering patterns for both forms are discussed in Paragraph 33.2.
33.1.1 Multiple Systems. TO data pertinent to more than one system in this category is numbered in the category general
series.
33.1.2 Multiple Equipment. Information relating to more than one equipment series within a system is numbered in the
system general series.
33.2 NUMBERING PATTERNS.
33.2.1 Group One. This group has three parts identifying the category, system and material series.
33.2.1.1 Part one is always the numeric 42 identifying Category 42.
33.2.1.2 Part two is an alpha character identifying the various systems, i.e., A - dopes, paints, and cleaning compounds; B
- fuels, lubricants, oxygen, and gases; C - chemicals; D - metals, plastics, and composition materials; E - rubber materials; F
- cordage, leather, and miscellaneous fabric; and L - lumber.
33.2.1.3 Part three contains one or more numeric characters identifying the material series within a system. The material
series numbers for this category are outlined in Paragraph 33.4.
33.2.2 Group Two. Since TO numbering patterns in Category 42 use both three and four basic groups, the identifiers in
group two are not constant. The following describes both numbering patterns:
33.2.2.1 If the TO number uses only three basic groups, group two will have a numeric character identifying all TOs as
being in a single, general Model-Type-Part Number series. This is due to the general or comprehensive nature of TO data in
this category.
33.2.2.2 If the TO number contains four basic groups, the equipment or material series identified in part three of group
one has been further divided into subseries. In this case, group two identifies the specific material subseries with one or more
numeric characters.
33.2.3 Group Three.
33.2.3.1 If the TO number has only three groups, the third group of the numbering pattern is made up of numeric
characters identifying individual TOs. Specific numbers are not reserved to identify specific types of TOs as in other
categories. In some instances the numeric characters are followed by one or more alpha characters indicating a series of
checklists, workcards or supplements. The following alpha characters are authorized for use in Category 42.
CL - Checklists
S - Operational Supplements
SS - Safety Supplements
WC - Workcards

33.2.3.2 If the TO number has four basic groups, the third group contains a numeric character identifying all TOs as being
in a single general Model-Type-Part Number series. This is due to the general or comprehensive nature of TO data in this
category.
33.2.4 Group Four. When the TO number has four basic groups, the fourth group is made up of numeric characters
identifying individual TOs. Specific numbers are not reserved to identify specific types of TOs as in other categories. In
some instances the numeric characters may be followed by one or more alpha characters described in Paragraph 33.2.3.1.

CATEGORY 44 - COMMON HARDWARE EQUIPMENT
35.1 GENERAL.
Category 44 contains two common hardware equipment systems. These systems are divided into equipment series and the
equipment series are further divided into equipment subseries. TO numbers in Category 44 use both three and four basic
groups for data identification. The numbering patterns for both forms are discussed in Paragraph 35.2.
35.1.1 Multiple Systems. TO data pertaining to more than one system in this category is numbered in the category
general series.
35.1.2 Multiple Equipment. Information relating to more than one equipment series within a system is numbered in the
system general series.
35.2 NUMBERING PATTERNS.
35.2.1 Group One. This group has three parts identifying the category, system and equipment series.
35.2.1.1 Part one is always the numeric 44 identifying Category 44.
35.2.1.2 Part two is an alpha character identifying the various hardware systems, i.e., B - bearings; and H - hardware.
35.2.1.3 Part three contains one or more numeric characters that identify the equipment series within a system. The
numbering series for this category is outlined in Paragraph 35.4.
35.2.2 Group Two. TO numbering patterns in Category 44 use both three and four basic groups; therefore, the identifiers
in group two are not constant. The following describes the numbering pattern for both forms:
35.2.2.1 If the TO number uses only three basic groups, group two contains one or more numeric characters representing
the model, type or PN assigned to specific equipment.
35.2.2.2 If the TO number contains four basic groups, the equipment series identified in part three of group one has been
further divided into equipment subseries. In this case, the equipment subseries is identified with one or more numeric
characters in group two, and the model, type or PN is identified in group three.
35.2.3 Group Three.
35.2.3.1 If a TO number has only three basic groups, the third group of the numbering pattern identifies the type of TO
(see Appendix C for a complete list of types of TOs). The following is a list of numbers reserved to identify specific types
of TOs in this category:
-1 Operating Instructions
-2 Service or Maintenance Manuals
-3 Depot Maintenance or Overhaul Instructions
-4 Illustrated Parts Breakdown

bering series for this category is outlined in Paragraph 40.4.
40.2.2 Group Two. TO numbering patterns in Category 50 use both three and four basic groups; therefore, the identifiers
in group two are not constant. The following describes the numbering pattern for both forms:
40.2.2.1 If only three groups are used in a numbering pattern, group two contains one or more numeric characters
representing the model, type or PN assigned to specific equipment.
40.2.2.2 If the TO number contains four basic groups, the equipment series identified in part three of group one has been
further divided into equipment subseries. In this case, the equipment series is identified with one or more numeric characters
in group two, and the model, type or PN is identified in group three.
40.2.3 Group Three.

CHAPTER 41
CATEGORY 51 - AUTOMATIC TEST SYSTEMS
41.1 GENERAL.
Normally test procedures, test control or programmed test TOs are numbered with related equipment in the various airborne
and ground component categories. However, TOs pertaining to depot level, automatic test equipment software and software
instruction manuals are numbered in Category 51. Three types of automatic test equipment numbered in this category can be
defined as Computer Operated Multifunction Electronic Test Stations (COMETS); General Purpose Automatic Test Systems
(GPATS); and Versatile Automatic Test Equipment Systems (VATES). GPATS and VATES TOs relate test modules to Line
Replaceable Units (LRUs) and Shop Replaceable Units (SRUs) of an airborne or ground system. COMETS TOs identify
LRUs and SRUs with a test system. Another basic difference between these automatic systems is GPATS and VATES test
software do not require computer memory banks for test operations and can only test singular Units Under Test (UUTs).
COMETS test software operates with computer memory banks and has the capability to test components of several systems
on one test station.
41.1.1 Primary Series. Automatic Test Equipment in Category 51 contains seven systems. These systems are divided into
equipment series and some of the equipment series are further divided into equipment subseries. TO numbers in this
category use both three and four basic groups for data identification. The numbering pattern for both forms are discussed in
Paragraph 41.2.
41.1.2 Multiple Series. TO data pertinent to more than one system in this category is numbered in the category general
series.
41.1.3 Multiple Equipment. Information relating to more than one equipment series within a system is numbered in the
category general series.
41.2 NUMBERING PATTERNS.
41.2.1 Group One. This group has three parts identifying the category, system and equipment series.
41.2.1.1 Part one is always the numeric 51 identifying Category 51.
41.2.1.2 Part two is an alpha character identifying the various systems, i.e., C - computer operated multifunction elec-
tronic test stations; E - aircraft engines; N - navigation instruments; P - radar equipment; T - master hardware; and V -
versatile automatic test equipment.
41.2.1.3 Part three contains one or more numeric characters identifying the equipment series within a system. The num-
bering series for this category is outlined in Paragraph 41.4.
41.2.2 Group Two. TO numbering patterns in Category 51 use both three and four basic groups; therefore, the identifiers
in group two are not constant. The following describes the numbering pattern for both forms:
41.2.2.1 If only three basic groups are used in a numbering pattern, group two contains one or more numeric characters
representing the model, type or PN assigned to specific equipment.
41.2.2.2 If the TO number contains four basic groups, the equipment series identified in part three of group one has been
further divided into equipment subseries. In this case, the equipment subseries is identified with one or more numeric
characters in group two, and the model, type or PN is identified in group three.

APPENDIX B
DEVELOPING TO TITLES
B.1 GENERAL.
A TO title relates to the subject and content so users can recognize the applicability of the TO and tell the difference between
TOs with similar applications. The TO title is used to determine the TO number Category and assign the last segment of the
TO number. TCTO Series Headers use abbreviated titles containing only the Mission/Design/Series (MDS - e.g., MODEL
B-52 SERIES H) or Type/ Model/ Series (TMS - e.g., TYPE AN/ARN131) of the systems or equipment covered. The TO
Manager will enter the specific titles of individual TCTOs when requesting TCTO number assignment. When a commercial
manual does not include a complete title, prepare an Identifying Technical Publication Sheet (ITPS) according to MIL-
HDBK-1221, Evaluation of Commercial Off-The-Shelf (COTS) Manuals, identifying the complete, accurate TO title and
any supplemental data provided.
B.2 RULES.
B.2.1 Standard Manuals. Do not enter ″TECHNICAL MANUAL″ as part of the TO title (included automatically by
MIL-STD-38784).
B.2.2 Preliminary Manuals. Do not enter the word ″PRELIMINARY″ for the same reason. Preliminary status is shown
by setting ETIMS ″flags″ during indexing.
B.2.3 Supplemental Manuals. Identify supplemental manuals in the first line of the title. Separate from the rest of the
title by a space, two dashes, and a space. Example: SUPPLEMENTAL MANUAL.
B.2.4 TO Type. In the next part of the TO title, list the type of TO (e.g., maintenance instructions, flight manual,
illustrated parts breakdown (IPB), etc.) to tell what kind of technical data is included in the TO and determine the ″Group
(segment) Three″ (TO type) portion of the TO number. Separate the type of TO or medium from the rest of the TO title by
using a space, two dashes, then a space. Exception: MIL-PRF-83495 TOs will be listed as shown in paragraph B.2.8, below.
B.2.4.1 Use only the types of TOs or media listed in TO 00-5-18.
B.2.4.2 Abbreviations may be used (OPR = Operation; INSTR = Instructions; MAINT = Maintenance; INTMD = Inter-
mediate; INSP = Inspection; etc.), but must be easily translatable.
B.2.4.3 Include ″INSTR″ in the title of any instructional TOs. Examples:
• FLIGHT MANUAL
• OPR INSTR
• MAINT INSTR
• JOB GUIDE
• CHECKLIST
• INTMD INSTR
• INSP REQUIREMENTS
B.2.4.4 If the TO consists of a combination of types, the types are listed in the order listed in TO 00-5-18 (e.g., operating
instructions (-1) first, maintenance instructions (- 2) next and parts list (PL) or IPB (-4) following).
• Examples:
TO 00-5-18
B-1
• OPR AND SVC INSTR
• MAINT INSTRU WITH IPB
• OVHL INSTR WITH IPB
• OPN AND SVC INSTR WITH PL
B.2.5 Level of Maintenance. The next part of the title identifies the intended level of maintenance if the TO is restricted
for use at a specified level. (Note that ″INTMD INSTR″ as used in paragraph B.2.4.3 above is not restricted to use at the
intermediate level.) Separate the intended level of maintenance from the rest of the title by using a comma and one space.
Examples:
• MAINT INSTRU - DEPOT
• ASSEMBLY, CHECKOUT, AND MAINT INSTRU - ORG AND INTMD
• CHECKLIST - MAINT INSTR, ORG (FLT LINE)
• MAINT INSTR WITH IPB - INTMD
B.2.6 MIL-PRF-83495. For MIL-PRF-83495 organizational maintenance manuals, the type of TO or medium and the
intended level of maintenance may be combined, followed by the function. Separate the type of TO and the level of
maintenance from the function with a space, two dashes, and a space. Separate the function from the main part of the TO
title by using a comma and a space. Examples:
• ORG MAINT - JOB GUIDE
• ORG MAINT - FAULT REPORTING
• ORG MAINT - GENERAL SYSTEM
B.2.7 Subject or Equipment. Enter the subject or the equipment identification in the main part of the title. List the
subject of the TO, or name of the equipment and the type, series, model and part number, in that order, when these elements
apply. The NSN may be shown if required. Enter the manufacturer name in parentheses following the equipment number. Do
not split a type, series, model or part number between two lines. The words type, series, model or part number are not
considered part of the number. Examples:
• IPB - HOT AIR SHUTOFF VALVE, MODEL CV-2S3.5, PN 105150-2 (STRATOS)
• OVHL INSTR WITH IPB - POWER SUPPLY, TYPE ECU-45/A, PN 28VS1006 (WAGNER)
B.2.8 Classification. List the TO title classification in parentheses following the main part of the title for classified TOs.
Examples:
• MAINT INSTR - INTMD, COUNTER-MEASURES RECEIVER
• TYPE R-1854/ALR-46(V), PN 31-032491-02 (ITEK) (TITLE UNCL)
NOTE
The classification of the TO and title is entered into ETIMS during the indexing process, and will appear as a ″U,″
″C″ or ″S″ in the TO detail screen of the TO catalog. The Department of Energy classifications for nuclear
weapons technical data classified as ″Restricted Data″ and ″Formerly Restricted Data″ are not currently supported
in ETIMS, and must be made part of the TO title when applicable.
B.2.9 Sectionalized Manual. When a proposed TO meets the criteria for a sectionalized manual (that is, it is sufficiently
large and has natural divisions in tasks or equipment breakout which make several smaller manuals more usable and more
manageable), each section must be numbered and indexed individually. A separate ETIMS ″Manage TM Numbering; Assign
TO 00-5-18
B-2
a Publication Number″ request must be submitted for each section. Each submittal lists the individual title and the relation-
ship of each section to the group is set using the ″Manage TM Index; Update an Index Entry″ process, ″Options; Update
Index Data; Publication Association″ function. The following examples show TO titles for a group of four sections, all
having the same basic TO number. Examples:
• IPB - RECEIVER GP, TYPE OA-2504/ALD-5 (RAYTHEON)
• IPB - SIGNAL ANALYSIS, PROGRAMMER GP, TYPE OA-2505/ALD-5 (RAYTHEON)
• IPB - INDICATOR RECORDER GP, TYPE OA-2506/ALD-5 (RAYTHEON)
• IPB - ANTENNA GP, TYPE OA-2507/ALD-5 (SYLVANIA)
B.2.10 Reference Manuals. Various terms are used to describe the test procedures or operator manuals and the reference
manuals which describe software-related instructions for embedded computers. These ″dash eight″ (-8) manuals contain
documentation on how to use software programs identified in the CPIN System to check out, test or maintain computer
hardware. The initiator ensures the title always identifies the specific function of the software documentation. Examples:
• CHECKOUT TAPE MANUAL - INDICATOR PANEL, TYPE RU-118, RADAR BOMB DIRECTING CENTRAL
TYPE AN/TSQ-96 (REEVES)
• TEST PROCEDURES MANUAL - CONTROL INTERCOMMUNICATIONS SET, C-9655/A, PN 3397101
(HUGHES)
B.2.11 Special Notations. List any special notations in parentheses, such as (FORMERLY TO 12R2-4-171-2), or (THIS
MANUAL INCOMPLETE WITHOUT TO 31M-2TMQ15-2), or (SA- ALC USE ONLY), or (USED WITH TO 36A11-21-
2). Only notations of a permanent nature about the TO itself are listed here. See ″4″ below for other catalog notes. Identify
commercial manuals with an entry in parentheses at the end of the title. Example:
• OPR INSTR - DODGE TRUCKS, MEDIUM AND HEAVY DUTY (COMMERCIAL MANUAL)
B.2.12 Contractor Data. Identify contractor data, as follows. Example:
• CONTRACTOR ACCEPTANCE REQUIREMENTS DOCUMENT AR30873-702
B.3 SYSTEM APPLICATION.
System application data is required both as part of the TO title and in the TO record in the ETIMS Pub Index. The data are
used to provide Lists of Applicable Publications (LOAPs) and to update USAF TO Catalog TO number to Equipment
number cross-reference data. The LOAPs provide an aid for selection of or familiarization with TOs for a specific system
and determination of TO file requirements. The Catalog cross-reference provides the capability to determine TO coverage for
a specific piece of equipment, and helps to prevent acquiring duplicate tech data between services. The capability to
withdraw data by system application requires consistent adherence to the rules below.
B.3.1 Prime System Application. Using the ″Manage TM Numbering; Assign a Publication Number″ process, enter only
applications to prime aircraft, missiles, space launch vehicles, C-E systems, and engines listed in the D086, Mission Work-
