Which document would you use to locate the approved repair procedures for damaged structural components such as a wing spar?

• A. Illustrated Parts Catalog
• B. Aircraft Maintenance Manual
• C. Wiring Diagram Manual
• D. Structural Repair Manual

Answer: (D)

When a primary structural component like a wing spar is damaged, you need the document that provides the approved repair procedures and limits for that structure. The Structural Repair Manual is written specifically to lay out the exact methods, materials, fasteners, and dimensional limits for repairing primary structures, along with the required inspections and nondestructive testing steps to ensure the repair maintains airworthiness. The Aircraft Maintenance Manual covers general maintenance and installation steps, not the detailed structural repair data. The Illustrated Parts Catalog is about identifying and locating parts, not how to repair them, and the Wiring Diagram Manual focuses on electrical circuits. So the Structural Repair Manual is the source for locating the approved repair procedures for structural components.
