What level maintenance is devoted to the repair (not overhaul), test, and return of serviceable status of unserviceable aeronautical components and equipment?

• A. Class A
• B. Class C
• C. Class B
• D. Class D

Answer: (B)

Repairing, testing, and returning unserviceable aeronautical components to serviceable status without performing an overhaul is handled at the intermediate maintenance level. This level is designed for troubleshooting and more than basic servicing, involving disassembly as needed, component repair or replacement, and thorough bench testing to verify proper operation before the item goes back into service. It sits between simple flight-line servicing and depot-level overhaul, which is reserved for major rebuilds. For example, if a radar indicator unit is found unserviceable, the intermediate shop would diagnose the fault, replace faulty parts or repair the circuit, reassemble, and run functional tests to confirm it operates correctly before returning it to service. Overhaul would involve a more extensive rebuild and is not part of this level’s scope.
