How can technicians verify the structural integrity of an aircraft post-repair?

Verifying the structural integrity of an aircraft post-repair is a critical process to ensure safety and performance. Performing thorough inspections and validations before returning the aircraft to service is integral to this verification process. This approach involves a combination of different checks, including non-destructive testing (NDT), functional checks, and detailed visual inspections of the repaired areas.

These inspections are essential because they check for potential issues such as material fatigue, incorrect installation of components, and compliance with regulatory standards. Ensuring all repairs adhere to technical and safety requirements helps to maintain the aircraft's operational reliability and safety for future flights.

While simulations and visual assessments play roles in the maintenance process, they are not as comprehensive or definitive in determining the structural integrity as a thorough set of inspections and validations. Hence, the practice of comprehensive inspections is the most reliable method to assure that the aircraft can safely return to service.
