Which action is required before returning to service after a repair that could affect operation?

• A. Test Flown by an Appropriately Rated Pilot and Approved for Return to Service
• B. Painted
• C. Log Entry Only
• D. Structural Test by An FAA Engineer

Answer: (A)

After a repair that could affect how the aircraft operates, it must be flight tested by someone who is appropriately rated and authorized to release the aircraft for return to service. This flight test verifies the repair functions correctly in actual flight conditions and confirms the aircraft is airworthy before it is returned to service. A paper log entry alone doesn’t prove airworthiness, and cosmetic work like painting doesn’t address flight safety. A structural test by an FAA engineer isn’t typically required for standard repairs; the authorized flight test and release provide the necessary verification.
