What must be done when there is a change in aircraft covering material from certified to non-certified materials?

When an aircraft undergoes a change in covering material from certified to non-certified materials, it is crucial to notify the FAA and expect inspection. This requirement is grounded in the regulations that govern aircraft maintenance and modifications. Certified materials have passed rigorous standards set by the FAA for safety and reliability, whereas non-certified materials may not meet these standards and could potentially affect the airworthiness of the aircraft.

By notifying the FAA, the change is formally acknowledged, and the necessary inspections can be arranged. This ensures that the modification meets all safety regulations and that the aircraft remains compliant with airworthiness standards. Additionally, the FAA can assess the implications of using non-certified materials on the aircraft's performance and safety.

The other choices, while they involve important aspects of aircraft maintenance, do not fulfill the specific requirement related to the change in covering materials. Proper notification to the FAA is essential to maintain the integrity and safety of the aircraft.
