What the FAA Airframe Test Covers
The Airframe knowledge test is defined by the Aviation Mechanic Airman Certification Standards (FAA-S-ACS-1), subject area AM.II. It tests the maintenance, repair, and alteration of aircraft structures and airframe systems. SkyLicense practice questions cover every AM.II subject area:
- Metallic and composite (non-metallic) structures
- Hydraulic and pneumatic power systems
- Landing gear — retraction, brakes, tires, steering
- Flight control systems — primary and secondary
- Aircraft fuel systems and fuel storage
- Cabin atmosphere, pressurization, and environmental control
- Fire protection and detection systems
- Aircraft electrical systems and wiring
Key references for Airframe study: AC 43.13-1B (accepted methods and practices) and the FAA Airframe Handbook (FAA-H-8083-31), alongside 14 CFR Parts 43 and 65.
Sample Airframe Practice Question
Sample Question · AM.II — Electrical Systems
In an aircraft electrical system, which component converts mechanical energy from the engine into electrical energy?
A. The voltage regulator
B. The alternator (generator)
C. The battery
D. The inverter
Answer: B — The alternator
The alternator (or generator) converts mechanical energy from the engine into electrical energy to power the aircraft electrical system and recharge the battery. The voltage regulator controls output voltage, the battery stores energy, and an inverter converts DC to AC.
How to Prepare for the FAA Airframe Test
- 1
Learn the AM.II subject areas first
Study each ACS subject area with the FAA Airframe Handbook (FAA-H-8083-31) and AC 43.13-1B before testing yourself.
- 2
Take timed full-length simulations
Run the 100-question, 2-hour Airframe simulation on SkyLicense. Practice pacing — you have about 72 seconds per question on test day.
- 3
Review explanations and retake weak areas
Use your per-subject score report to target weak topics, then retake simulations until you consistently score above 80%.

Airframe Practice Test FAQ
How many questions are on the FAA Airframe knowledge test?
The FAA Airframe knowledge test has 100 multiple-choice questions. You have 2 hours to complete it and must score 70% or higher — 70 correct answers — to pass. The test covers ACS subject area AM.II (Airframe).
What topics are covered on the FAA Airframe test?
The FAA Airframe test covers aircraft structures and airframe systems per the Aviation Mechanic ACS (FAA-S-ACS-1), subject area AM.II: metallic and composite structures, hydraulic and pneumatic systems, landing gear, flight controls, fuel systems, cabin atmosphere and pressurization, fire protection, and aircraft electrical systems.
Is the Airframe knowledge test required for an A&P certificate?
Yes, if you are pursuing the Airframe rating. Every mechanic candidate must pass the General knowledge test, plus the Airframe test for the Airframe rating and the Powerplant test for the Powerplant rating. Most mechanics pass all three and hold both ratings (A&P).
Where do I take the FAA Airframe knowledge test?
You take the FAA Airframe knowledge test at an FAA-approved computer testing center operated by the FAA testing service, PSI. You schedule the test after completing FAA Form 8610-2. The test is the same nationwide — 100 questions, 2 hours, 70% pass mark.
What is the passing score for the Airframe test?
The passing score is 70%. On the 100-question Airframe knowledge test, that means you must answer at least 70 questions correctly. The Airframe and Powerplant tests both use this rule, while the 60-question General test requires 42 correct answers.
How long should I study for the FAA Airframe test?
Most candidates study 4–6 weeks per knowledge test. Focus on the ACS AM.II subject areas, practice with timed simulations, and track your score per topic. When you can consistently score above 80% on practice tests, you are ready for the real exam.
Pass the Airframe Test with Confidence
Practice 100-question timed simulations, review ACS-aligned explanations, and track your score on every AM.II subject area.
