FOREWORD

1. This standard is approved for use by the Department of the Air Force and is available for use by all Departments and Agencies of the Department of Defense.

2. In order to provide standardization between publications a standardized numbering system has been developed. It is designed with sufficient flexibility to permit expansion and application outside the technical manual system to support logistics elements that interact with or directly influence equipment maintenance and technical manual development and use.

3. To ensure maximum flexibility, gaps have been left in the system and subsystem numbering sequences.

Manufacturers are encouraged to use the unassigned systems and subsystems to accommodate unique design or emerging technologies when required, as approved by the procuring activity and current acquisition policy.

Please provide any suggested changes to the Air Force Technical Manual Specifications and Standards (TMSS) office at the address in item 6 below.

4. As a minimum, this standard is intended to be used in conjunction with MIL-DTL-83495 and MIL-HDBK-863. Additional applications are available as defined in the documents identified in section 2.

5. The purpose of change 2 is to incorporate minor editorial changes and add hyperlinks to references for ease of use as needed.

6. Comments, suggestions, or questions on this document should be addressed to AFLCMC/HIS Technical Data Section, 4170 Hebble Creek Road, Bldg. 280, Door 15, Area A, Wright-Patterson AFB, OH 45433-5653 or emailed to SGMLsupport@us.af.mil.

3 DEFINITIONS

3.1 Definitions. Definitions will be in accordance with the documents listed in section 2.

4 GENERAL REQUIREMENTS

4.1 System Subsystem Sub-subsystem Number (SSSN). The SSSN referencing shall be used to locate needed data for the technical information required by those documents listed in section 2. Broad rules for applying the SSSN are outlined herein. The SSSN numbering system is a dash number breakdown that provides a means for dividing information into system, subsystem, and sub-subsystem. The following instructions provide general procedures for constructing the SSSN using the numbers assigned herein. The SSSN shall be used in conjunction with the functional requirements of MIL-DTL-9854, MIL-DTL-38807, and MIL-DTL-83495.

4.1.1 Number composition. The basic SSSN is composed of two- and three-digit elements (see table I).

The first element (system) and the first digit of the second element (subsystem) are assigned as specified herein (see section 5). The second digit of the second element (sub-subsystem) and the third element (subject) are assigned by the manufacturer according to the complexity of the equipment and the numbering application. The fourth element (function) is used when typical maintenance functions are required.

Depending on program needs, such as supportability analysis, configuration management, work unit codes, engineering data, etc., additional elements may be added to the right.

4.1.1.1 System number. When assigning system or subsystem numbers to information applicable to a whole system or whole subsystem zeros shall occupy the applicable elements and digits of the SSSN. For example, information about the complete Navigation system located in an On-equipment Maintenance Manual Set (OMMS), General System (GS) manual would be assigned the SSSN 34-00-00. Information contained in this manual must be applicable to the entire Navigation system.

4.1.1.2 Subsystem number. Continuing the example in 4.1.1.1, if subsystems are so complex that the information cannot be practically covered, additional subsystem breakouts may be required. The information in these manuals would be confined to the specific subsystem, e.g., information for the Dependent Position Determining subsystem would be assigned 34-50-00.

4.1.1.3 Sub-subsystem number. Systems designed with very complex subsystems may require further breakout into sub-subsystems. The sub-subsystem element numbers and descriptions are defined by the manufacturer. Sub-subsystems shall be indicated by a number greater than zero in the second element, second digit, e.g., 34-51-00. In this case, -51 represents a sub-subsystem, e.g., Global Positioning System (GPS), of the Dependent Position Determining subsystem (34-50-00) of the Navigation system (34-00-00).

4.1.1.4 Subject number. The subject number is assigned by the manufacturer and generally identifies tasks or components. This number shall be assigned in consecutive order within the manual or view package, e.g., the fifth subject in a Job Guide (JG) would be XX-XX-05.

4.1.1.5 Function number. When used, the function number shall be assigned as prescribed by MIL-DTL-83495. (See TABLE I.)

5 DETAIL REQUIREMENTS

5.1 Use of SSSN. The SSSN shall be used as described in the documents cited in section 2. System and subsystem numbers are assigned as specified herein, as required.

Submit requests for use of unassigned SSSN numbers by e-mail to the TMSS Helpdesk at SGMLsupport@us.af.mil.

5.2 System numbering. The following system, subsystem numbers, and titles shall be used, as required by equipment design and as required by the documents listed in section 2.
