identifies the manufacturer (Lockheed) of the P-3C aircraft; and the 02B-10 in part (E) identifies the manufacturer (Pratt and Whitney) of the jet engine power plant.

Part III of the publications suffix number may or may not have identifiable numerical significance within the airframe, missile, and power plant series. The number usually identifies a particular type of manual; for example, NAVAIR 01-XXXX-1 (-1 NATOPS), NAVAIR 01-XXXX-2 (-2 maintenance), NAVAIR 01- XXXX-3 (-3 structural repair), and NAVAIR 01-XXXX-4 (-4 IPB). Additional numbers may be added to indicate system grouping breakout by volume or subsystem grouping by subvolume (i.e., NA 01-XXXX-2-2). The second -2 indicates the second volume of the maintenance series, which is usually grouped by system. If the number assignment is NAVAIR 01-XXXX-2-2.3, the .3 indicates a subvolume or subsystem within a grouping. Refer to figure 3-2 for specific examples of technical manual number assignments. However, this system does not hold true in all cases. In many technical manual number assignments, the suffix numbers are assigned in numerical sequence for identification only, and they have no significant meaning.

Technical Manual Identification Numbering System (TMINS)

The TMINS numbering system was developed in coordination with other systems commands. It was developed in response to the project sponsored by the Naval Material (NAVMAT) Command to standardize technical manual numbers for all ships, aircraft and equipment, and their method of assignment throughout the Navy. To establish policies and guidelines of the TMINS, the Commander of Naval Material (CNM) issued NAVMATINST 4160.1. In response, NAVAIR issued its own instruction - NAVAIRINST 4160.1. This instruction is tailored after the NAVMAT- INST and establishes the TMINS for aeronautic publications. The TMINS provides a single user- oriented numbering and indexing system. It satisfies the requirements of all systems commands for identifying, referencing, and requisitioning technical manuals and changes. The system also makes the identification and ordering of manuals easier for the operating forces and other users. It is compatible with automatic data processing (ADP) manipulation procedures. Subsequently, NAVMAT issued an application guide and index, M0000-00-IDX-000/TMINS. This guide and index should be available in the technical library. By using the guide and index, you will be able to understand and use the TMINS.

NOTE: The Naval Material Command was disestablished, effective 6 May 1985, as the controlling authority over the systems commands. All systems commands now report directly to CNO. The cognizant authority for NAVMAT- INST 4160.1 is now Naval Sea Systems Command (NAVSEASYSCOM).

The TMINS assigns each technical manual a unique identifying alphanumeric designation, patterned after the 13-digit national stock number (NSN); for example, 0000-LP-000-0000. It serves as the technical manual identification number and as the national stock number used to requisition the manual. Additionally, TMINS contains a provision for adding a suffix to give the security classification and other information considered important. While reading the remainder of this section, you should look at figure 3-3.

TMINS NUMBER COMPOSITION. - The standard TMINS number (fig. 3-3) is made up of two distinct parts separated by a slash (/). The first part of the TMINS is called the publication identifier (PI). It is the essential root of the number. The PI is always used, and it is always made up of exactly 13 characters.

The second part of the TMINs is called the suffix. It is an added field of up to 17 characters (including the slash). When used, it gives user- oriented information. The suffix is always used for classified manuals and separately bound unclassified portions of classified technical manuals. The suffix for both classified and unclassified TMINS may also give the use equipment designation, nomenclature, model, or hull number information.

PI COMPOSITION. - The publication identifier is made up of two major components: the hardware/subject identifier and the technical manual (TM) identifier. The first seven characters of the PI make up the hardware/subject identifier. These characters identify the specific hardware (such as an aircraft) or subject (such as an airborne weapons system) to which the technical manual applies. Once the project serial number is assigned (for example, SA-AN/APS-39A radar
