Who is responsible for ensuring appropriate entries are made in maintenance records indicating the aircraft has been approved for return to service?

• A. Owner or operator
• B. Maintenance technician
• C. Mechanic
• D. Flight instructor

Answer: (A)

The key point is that the owner or operator is responsible for maintenance records, including ensuring the aircraft has an entry showing it has been approved for return to service. While the actual work is performed and the return-to-service approval signed by the person who did the maintenance or supervised it, the owner or operator must make sure the maintenance records are complete, accurate, and up to date before flight. This responsibility stems from the need to prove the aircraft is airworthy and properly documented. The maintenance technician or mechanic may perform the work and sign off on the specifics, but they don’t bear the overarching responsibility for the record-keeping. A flight instructor isn’t involved in the maintenance records for return to service.
