A manufacturer's maintenance manual is considered mandatory during an annual inspection when it is part of an approved inspection program. This is crucial because approved inspection programs are established to ensure that all maintenance practices adhere to regulatory requirements and safety standards. These manuals typically provide detailed procedures, specifications, and guidelines that are essential for the proper inspection and maintenance of specific aircraft and their components. Therefore, reliance on the manufacturer's documentation is fundamental for compliance and safety when an aircraft is undergoing an annual inspection as part of an approved program.

The inclusion of such manuals in the inspection process supports the airworthiness and operational integrity of the aircraft. When proper procedures outlined in the manufacturer’s maintenance manual are followed, it fosters consistency and enhances the reliability of maintenance work performed.
