FAA certification Overview - (PART III)

FAA Aviation Mechanic Certification Overview

• the The Aviation Mechanic certificate has two main ratings: Airframe and Powerplant. Candidates can earn one or both (A&P Certificate).
• Eligibility includes being at least 18 years old, ability to read, write, speak, and understand English, and meeting experience requirements (18 months for one rating or 30 months for both).
• Tests include three knowledge (written) tests (General, Airframe, Powerplant), plus oral and practical tests conducted by a Designated Mechanic Examiner (DME).​

‍

Topics Covered in Oral and Practical Tests

• General (Section I): Includes 12 subjects such as aviation mechanic privileges and limitations, basic maintenance practices, use of tools, welding and soldering, corrosion control, inspection, weight and balance, and regulations.
• Airframe (Sections II and III):
  • Section II (Airframe Structures): 7 subjects, including wood, metal, and composite structures, aircraft covering, and structural repairs.
  • Section III (Airframe Systems and Components): 10 subjects covering electrical systems, instruments, landing gear, hydraulics, pneumatics, flight controls, and environmental systems.
• Powerplant (Sections IV and V):
  • Section IV (Powerplant Theory): 3 subjects focused on engine theory, including reciprocating and turbine engines.
  • Section V (Powerplant Systems and Components): 12 subjects such as fuel systems, ignition, lubrication, cooling, engine instruments, starting systems, and exhaust systems.

Test Structure

• The oral test involves verbal questioning by a Designated Mechanic Examiner (DME), focusing on demonstrating knowledge and understanding of these subjects.
• The practical test requires candidates to perform hands-on tasks related to aircraft maintenance and repair, demonstrating skills in inspections, troubleshooting, repairs, and the use of tools and equipment.
• The tests are designed to evaluate real-world maintenance skills, comprehension of FAA regulations, and safety procedures.
• Candidates seeking both Airframe and Powerplant certificates must pass all five sections. Those with one rating seeking the other only need the relevant supplementary sections.
• Each section includes both knowledge (oral) and skill (practical) elements, and all must be passed to pass the section.

This mix of technical, regulatory, and situational questions will prepare you well for the FAA mechanic oral and practical test interviews.
