In the NAVAIR Conventional Numbering System, how many parts are there separated by dashes?

• A. Three
• B. Two
• C. Four
• D. One

Answer: (A)

Three parts. The NAVAIR Conventional Numbering System uses three segments separated by dashes, each serving a different level of identification: the broad category or platform, the subsystem or function, and the specific item within that subsystem. The dash marks the boundary between these fields, so a designation reads as category–subsystem–item. This three-part structure keeps components organized and easy to reference across maintenance and supply, with an illustrative format like 01-15-03 meaning category 01, subsystem 15, item 03.
