For aircraft operated under part 91, when is aircraft total time required to be recorded in aircraft maintenance records?

• A. Before inspections
• B. After satisfactorily completing inspections
• C. During inspections
• D. Only when total flight time changes

Answer: (B)

The main idea is that maintenance records must show the aircraft’s total time in service as of when the work is officially completed and the aircraft is approved for flight. You record this after the inspections are satisfactorily completed because that’s the moment the work is finished, the aircraft is deemed airworthy, and the log entry is finalized. In practice, every maintenance or inspection entry includes the date, a description of what was done, the total time in service on the airframe (and any relevant components) as of completion, and the signer’s identification. This timing ensures the record accurately reflects the aircraft’s age and status at the point it is released for flight, which is essential for correctly scheduling future inspections and assuring traceability. So you don’t record the total time before finishing the work or while the inspection is in progress, and it isn’t dependent on whether flight time changed during the maintenance. The value you log is the airframe’s total time in service as of the completion of the maintenance and the aircraft being cleared for return to service.
