What must be accomplished before an aircraft can be approved for return to service after major repairs?

The requirement that approved data must be used is critical for ensuring that repairs are conducted according to established safety and regulatory standards. This means that any major repairs must follow specifications and procedures that have been vetted for safety, reliability, and compliance with regulatory bodies. Approved data can include approved repair manuals, technical data from the manufacturer, or other relevant documents that outline the proper techniques for the repair being conducted.

Utilizing approved data ensures that the integrity of the aircraft is maintained and that the repair is performed in a manner that meets industry standards. This is essential for safety, as it minimizes the risk of future issues that could arise from improper repairs. In the context of aircraft maintenance and regulation, adherence to approved data is a foundational principle.

The other options may contribute to the overall process but do not encompass the primary requirement for returning an aircraft to service after major repairs. For example, while a repair station’s inspection and the involvement of a licensed mechanic are important components of the repair process, they are governed by the stipulation of using approved data. Similarly, the presence of a pilot is not a standard requirement for the repair process itself. Thus, having approved data assures that the repair meets all necessary regulations and standards, solidifying its importance in the return-to-service
