Replacement of fabric on fabric-covered parts is considered a major repair.

• A. Minor repair
• B. Major repair
• C. Cosmetic maintenance
• D. Routine service

Answer: (B)

Replacing fabric on fabric-covered parts is a major repair because it directly alters a large, load-bearing and aero-surfaces system. The job goes beyond a small patch or cosmetic work: it requires removing the old fabric, inspecting the underlying structure for damage, attaching and tensioning new fabric to exact specifications, sealing or finishing seams, and ensuring the surface maintains proper aerodynamic shape and strength. Because it affects the aircraft’s structural integrity and flight characteristics, this type of work is treated as a major repair, needing approved repair data, thorough workmanship, and likely additional inspections or testing to verify airworthiness.
