Sample A&P - Certified Airframe and Powerplant Mechanics Practice Questions

Try these questions from our free A&P - Certified Airframe and Powerplant Mechanics practice tests. The correct answer and an explanation follow each question.

  1. Which FAA regulation part governs the certification and maintenance of airframe and powerplant mechanics?

    • A. 14 CFR Part 91
    • B. 14 CFR Part 43
    • C. 14 CFR Part 25
    • D. 14 CFR Part 61

    Answer: B. 14 CFR Part 43

    14 CFR Part 43, titled 'Maintenance, Preventive Maintenance, Rebuilding, and Alteration,' outlines the general rules governing these activities for aircraft. It specifies who can perform these actions, the methods, techniques, and practices to be used, and the record-keeping requirements. This regulation directly impacts A&P mechanics by defining the scope and standards of their work.

  2. What is the purpose of corrosion prevention in airframe maintenance?

    • A. To improve fuel efficiency.
    • B. To enhance the aircraft's paint finish.
    • C. To maintain structural strength and longevity.
    • D. To reduce radio interference.

    Answer: C. To maintain structural strength and longevity.

    Corrosion prevention is paramount in airframe maintenance because corrosion can severely degrade the structural integrity of aircraft components, leading to reduced strength and potential failure. Implementing effective corrosion control measures ensures the aircraft's continued airworthiness, extends its service life, and maintains overall flight safety. It is a continuous process.

  3. What is the primary function of the powerplant in an aircraft?

    • A. To provide structural support for the wings.
    • B. To generate thrust or power for flight.
    • C. To control cabin pressurization.
    • D. To house the flight crew.

    Answer: B. To generate thrust or power for flight.

    The powerplant of an aircraft refers to the engine(s) and associated systems that generate the necessary thrust or power to propel the aircraft through the air. Whether it's a reciprocating engine or a turbine engine, its primary function is to convert fuel into mechanical energy, enabling flight. Without the powerplant, the aircraft cannot achieve propulsion.

  4. What is the function of a wing spar in the airframe?

    • A. To house the fuel tanks.
    • B. To provide the primary structural support for the wings.
    • C. To control the aircraft's yaw.
    • D. To reduce drag during flight.

    Answer: B. To provide the primary structural support for the wings.

    Wing spars are the primary structural members that run spanwise through the wings, extending from the fuselage to the wingtip. Their crucial function is to carry the main bending loads and shear forces experienced by the wing during flight. This provides the essential strength and rigidity required for the wing structure to support the aircraft.
