Which statement about fabric replacement on fabric-covered parts is correct?

• A. It is a minor repair
• B. It is a routine service
• C. It is cosmetic maintenance
• D. It is a major repair

Answer: (D)

Fabric-covered surfaces are part of the structure, not just a superficial layer. Replacing the fabric involves removing the old covering, inspecting and repairing the underlying framework for damage, applying new fabric under precise tension, sealing and finishing, and verifying proper performance. This process can change the strength, load paths, and aerodynamics of the surface, so it requires careful procedures, proper documentation, and skilled workmanship. Because of the potential impact on safety and airworthiness, fabric replacement is a major repair. It’s not simply a minor fix, routine upkeep, or cosmetic work—the overhaul directly affects the aircraft’s structural integrity and flight characteristics.
