In the NAVAIR Conventional Numbering System, what does Part 3 identify?

• A. A particular type of manual
• B. The aircraft model
• C. The general subject classification
• D. The prefix

Answer: (A)

Part 3 identifies the particular type of manual. In the NAVAIR Conventional Numbering System, the code is organized to tell you what you’re looking at at a glance: the first part covers the general subject or system, the second part ties it to a specific aircraft model or subject area, and the third part designates the manual’s category or function (such as a maintenance manual, service guide, illustrated parts catalog, etc.). This structure helps technicians quickly determine the nature of the document before opening it. The other elements in the code serve different purposes—one part points to the broader subject, another to the aircraft/model, and the prefix is used for organizational grouping rather than classifying the manual type.
