A certificated mechanic with a powerplant rating may perform a major repair to a propeller provided they have the necessary equipment.

• A. Altimeter
• B. Propeller
• C. Airspeed indicator
• D. Tachometer

Answer: (B)

This question tests who is authorized to perform major repairs on a propeller. A certificated mechanic with a powerplant rating is allowed to work on propellers at a major repair level, as long as they have the necessary equipment and follow approved procedures. The propeller is part of the powerplant system, so work on it falls under powerplant certification, not under airframe or purely instrumentation tasks. The other items listed are flight instruments and gauges; they aren’t involved in propeller repairs, so they’re not relevant to this authorization.
