Regarding the following statements, which is true? “(1) Certificated mechanic with an airframe rating may perform a minor repair to an airspeed indicator providing they have the necessary equipment available. (2) Certificated mechanics with a powerplant rating may perform a major repair to a propeller providing they have the necessary equipment available.”

Regarding the following statements, which is true? “(1) Certificated mechanic with an airframe rating may perform a minor repair to an airspeed indicator providing they have the necessary equipment available. (2) Certificated mechanics with a powerplant rating may perform a major repair to a propeller providing they have the necessary equipment available.”

• A. Only statement 1 is true
• B. Only statement 2 is true
• C. Both statements are true
• D. Neither statement is true

Answer: (D)

The correct choice reflects that both statements are false according to FAA regulations regarding the privileges of certificated mechanics. In the case of the first statement, a certificated mechanic with an airframe rating is indeed allowed to perform minor repairs, but modifications to instruments such as airspeed indicators are often considered to require further certification or specialized knowledge. Since airspeed indicators are part of the aircraft's instrumentation, which may involve safety aspects and operational integrity, a mechanic's airframe rating does not inherently grant the authority to make repairs on such instruments, thus rendering this statement false. In the second statement, while a certificated mechanic with a powerplant rating does have the authority to perform maintenance, inspections, and some repairs on powerplants, the repair of a propeller is classified as a specific task. Since propellers fall under a different category governed by separate FAA regulations and specific qualifications, a powerplant-rated mechanic does not have the requisite authority to perform major repairs on propellers. Therefore, this statement is also considered false. This clarification helps understand the regulatory boundaries set by the FAA regarding the specific ratings and privileges assigned to mechanics.
