What should a pilot do if substantial repairs have been made to an aircraft?

When substantial repairs have been made to an aircraft, having it test flown and approved for service is essential for ensuring safety and compliance with aviation regulations. Substantial repairs might involve critical components of the aircraft that affect its performance, safety, or structural integrity.

After such repairs, it's vital to conduct a test flight to verify that the aircraft operates as expected under normal flight conditions. This test flight helps to confirm that the repairs were successful and that there are no lingering issues that could affect the aircraft's airworthiness. The test pilot, often certified and knowledgeable about the specific aircraft, can assess the repairs in flight, ensuring that the modifications meet required standards.

This approach is in line with FAA regulations and best practices in aviation maintenance, which emphasize that substantial modifications or repairs warrant thorough evaluation before the aircraft is returned to regular service. This process not only promotes the safety of the pilot and passengers but also reinforces the integrity of the aircraft's operational history.
