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

The correct choice reflects the responsibilities outlined in aviation maintenance regulations. After an annual, 100-hour, or progressive inspection, it is the duty of the person who has approved or disapproved the aircraft for return to service to make the appropriate entry in the maintenance records. This person holds the certification and authority to ensure that all necessary inspections have been completed, and they must document their findings and the status of the aircraft in the records.

This entry is crucial as it provides a clear history of the maintenance performed on the aircraft, which is vital for safety and regulatory compliance. The integrity of the maintenance records relies on having qualified personnel accountable for these entries, and it reinforces the importance of oversight in aviation maintenance procedures.

Other roles, such as the aircraft owner or maintenance inspector, do not bear the direct responsibility for this documentation. Additionally, while a manufacturer's representative might have a role in certain inspections or maintenance tasks, they typically do not have the authority to approve or disapprove a return to service in the context of regulatory requirements. Thus, the responsibility lies with the person who holds that certification to ensure the aircraft meets all safety standards and is properly documented before returning to operation.
