Under Part 145, which item is NOT listed as a repair category?

• A. Airframe
• B. Powerplant
• C. Instrument
• D. Navigation

Answer: (D)

Part 145 repair categories define the areas a repair station is authorized to work in: airframe, powerplant, instruments, and radio. Navigation isn’t listed as its own category; navigation equipment falls under the radio category. So the item not listed as a repair category is Navigation. If a shop wants to repair navigation gear, it would rely on its radio category rating.
