Where can examples of acceptable repairs to aluminum alloy propeller blades be found?

• A. In AC 43.13-1B, Chapter 8, Section 4, and in the propeller manufacturer's service manuals.
• B. In the engine repair manual.
• C. In the aircraft maintenance manual.
• D. In the Aeronautical Information Manual.

Answer: (A)

The key idea is that acceptable repair data for aluminum alloy propeller blades comes from official, FAA-approved sources. Specifically, AC 43.13-1B contains the accepted methods, techniques, and practices for various repair scenarios, and Chapter 8, Section 4 covers repairs for aluminum alloy propeller blades. In addition, the propeller manufacturer’s service manuals provide blade-specific repair instructions that are approved for that particular propeller design. Using these sources ensures repairs meet airworthiness standards and don’t compromise blade strength, balance, or safety. Other sources aren’t as appropriate because the engine repair manual focuses on engine components, not blade repairs; the aircraft maintenance manual is typically too general for the specific, approved repair data required; and the Aeronautical Information Manual is informational and does not substitute for repair data.
