Who is responsible for making the entry in the maintenance records after an annual 100 hour or progressive inspection?

The individual responsible for making the entry in the maintenance records after an annual 100-hour or progressive inspection is the person who is approving or disapproving for return to service (RTS). This person typically holds the necessary certification and authority, such as a licensed mechanic or an inspector, and is responsible for ensuring that all work performed complies with regulatory standards and that the aircraft is safe for operation.

This responsibility is tied to the regulatory requirements set forth by the Federal Aviation Administration (FAA), which mandates that the maintenance records must accurately reflect the condition of the aircraft following inspections. The approval process is crucial because it not only involves the technical assessment of the aircraft's components and systems but also the legal responsibility for documenting that these inspections were completed satisfactorily.

While the owner or operator of the aircraft may maintain overall responsibility for ensuring the aircraft is properly maintained, they do not have the authority to make changes or approvals in the maintenance records unless they are also a certified technician. Having a designee or inspector representing the FAA does not typically involve making entries in the maintenance records; instead, they ensure compliance during oversight and regulation. Not just any mechanic can make these entries, as only those with the appropriate certifications and authority can officially document maintenance activities.
