What document would you use to find an approved repair for a damaged wing spar?

• A. The illustrated parts catalog.
• B. The structural repair manual for the aircraft.
• C. The weight and balance manual.
• D. The wiring diagram manual.

Answer: (B)

When a wing spar is damaged, you must follow the manufacturer’s approved repair data. The Structural Repair Manual for the aircraft is the source that contains those approved methods, including how to repair, what materials and fasteners to use, any reinforcement requirements, drill and fastener patterns, and the post-repair inspection criteria. This ensures the repair restores the spar’s strength and keeps the airplane airworthy. The illustrated parts catalog lists parts and part numbers, not repair procedures. The weight and balance manual covers loading limits and center-of-gravity calculations, not structural repairs. The wiring diagram manual deals with electrical circuits, not structural integrity.
