Who is responsible for making the necessary entries in maintenance records after inspections like annual or 100-hour inspections?

The individual responsible for making the necessary entries in maintenance records after inspections, such as annual or 100-hour inspections, is the person approving or disapproving return to service. This person holds the responsibility for ensuring that all regulatory requirements have been fulfilled and that the aircraft is safe for operation.

The entries made in maintenance records serve as formal documentation of the inspection and any maintenance performed. This is crucial for compliance with aviation regulations set forth by the FAA. It also plays a significant role in the ongoing airworthiness of the aircraft. By approving or disapproving the return to service, the responsible person verifies that the maintenance work meets all the necessary safety standards and is in accordance with outlined procedures.

Other roles mentioned may have responsibilities related to inspection or maintenance documentation, but they do not hold the primary accountability for the records following inspections. The FAA designee or inspector may conduct the inspections but relies on the person approving the return to service for proper record-keeping. While the aircraft owner or operator has a vested interest in maintaining the aircraft and ensuring that records are kept, it is not their role to make these specific entries following inspections. The Technical Librarian typically manages documentation and reference materials rather than direct maintenance record entries.
