Who makes the final maintenance record entry after a 100-hour inspection is completed?

The final maintenance record entry after a 100-hour inspection is made by the person approving the aircraft for return to service. This requirement is established by FAA regulations to ensure accountability and traceability in the maintenance processes of aircraft.

In this context, the individual who is authorized to approve the aircraft for return to service is usually a certified mechanic who holds the necessary certifications and qualifications. This approval process is crucial because it signifies that the aircraft has been inspected thoroughly and complies with safety standards prior to being put back into operation. The action of making this entry ensures that there is a formal acknowledgment of the maintenance performed, including any findings and discrepancies noted during the inspection.

Typical practices regarding other roles, such as the aircraft owner, chief mechanic, or maintenance supervisor, do not involve making the final entry unless they hold the necessary certification and are designated to do so. This ensures that only qualified personnel are responsible for affirming the aircraft's airworthiness following maintenance activities.
