What is the extent of the repairs a mechanic with a Powerplant rating can make to a propeller?

• A. Major repairs.
• B. Major repairs or alterations.
• C. Minor repairs or minor alterations.
• D. Only minor repairs or minor alterations.

Answer: (D)

With a Powerplant rating, a mechanic is authorized to perform only minor repairs or minor alterations to a propeller. This limits you from undertaking major repairs or alterations, which are beyond the scope of a powerplant-rated mechanic. The idea is to keep work on the propeller within a level of supervision and certification that matches the complexity and safety implications of major rework. If a propeller needs major repair or alteration, it must be handled by someone with a higher or more appropriate rating (or by a certified propeller service facility) and documented accordingly. After completing any allowed minor work, proper certification and maintenance release are still required.
