How many parts does the NAVAIR conventional numbering system have?

• A. 2
• B. 3
• C. 4
• D. 5

Answer: (B)

Three parts. The NAVAIR conventional numbering system uses three distinct sections that together identify an item: the general item family, the exact item within that family, and the modification or revision level. These three segments, typically shown as a series separated by hyphens, let you quickly determine what the item is, exactly which part you’re dealing with, and whether it has any modification. If there were only two parts, you’d risk ambiguity between item type and the specific part; more than three parts would add unnecessary complexity without adding practical clarity for Navy items. So the standard convention is three parts.
