Who needs to inspect major fabric repairs?

The correct choice emphasizes the necessity for inspections to be conducted by an airframe and powerplant mechanic who possesses inspection authorization. This qualification is crucial because such mechanics have undergone additional training and certification, specifically designed to ensure they have the expertise to evaluate complex repairs, including those related to aircraft fabric covering. Their role is centralized around maintaining and ensuring the airworthiness of aircraft, which includes thorough inspections of significant repairs that could affect the overall structural integrity and safety of the aircraft.

Major fabric repairs can have serious implications on an aircraft's performance, making it essential to have a qualified inspector with authority to validate that repairs meet the necessary regulations and standards set by aviation authorities. This ensures the repairs are not only performed correctly but also comply with safety mandates.

While other professionals may have important roles in the repair and maintenance process, they may not possess the specific inspection authorization that is mandated for major repairs. This validation process is critical to maintaining safety standards and ensuring that all repairs can withstand the operational demands placed on aircraft.
