If an inspection is due at 1,050 hours, under what condition can an aircraft be flown beyond that time?

Flying an aircraft beyond an inspection due time of 1,050 hours is permissible when an Aviation Medical Examiner (AME) provides written confirmation of an extension. This is because the AME's confirmation serves as an official acknowledgment that the aircraft's condition permits continued operation beyond the established inspection time frame. The verification from the AME ensures that the aircraft remains safe to operate and that any potential issues have been appropriately addressed.

An AME has the requisite knowledge to evaluate the aircraft's status and determine if it's safe for continued operation until the next inspection can be performed. In this context, they play a crucial role in aviation safety by providing that assurance, mitigating risk for both the pilot and the public.

The other conditions mentioned do not satisfy the requirement to legally operate the aircraft beyond its inspection due time. Consequently, only the written extension from an AME guarantees that the aircraft remains compliant with safety standards while exceeding the standard inspection intervals.
