The A&P test: General, Airframe and Powerplant knowledge tests

The written part of the A&P test is three separate knowledge tests from the Federal Aviation Administration (FAA): Aviation Maintenance Technician General (AMG), Airframe (AMA) and Powerplant (AMP). General has 60 questions and the other two have 100 each. You get 2 hours for each test and need 70% to pass. Everyone takes General first, then the test for each rating they want. They’re multiple choice on a computer at a PSI test center, and you must pass them before the oral and practical tests.

  • 60Questions on the General (AMG) test
  • 100Questions each on Airframe and Powerplant
  • 2 hoursTime allowed for each test

How many questions are on the A&P test?

The FAA’s Airman Knowledge Testing Matrix, revised September 25, 2026, gives these figures:

TestQuestionsHoursPass
AMG: General602.070
AMA: Airframe1002.070
AMP: Powerplant1002.070

The minimum passing grade of 70% is set in Title 14 of the Code of Federal Regulations (14 CFR) 65.17. Each question has a single correct answer and doesn’t depend on any other question, the FAA’s companion guide to the mechanic Airman Certification Standards (ACS) says. You only pass General once: if you add a rating later, you take just that rating’s test.

The test may also include unscored validation questions. They aren’t in the question count, but they are in the 2 hours, the matrix says.

What the General test covers

The companion guide publishes a blueprint for each test. On the General test, each of these 12 areas makes up 5 to 10% of the questions, except electricity and ground operations, at 5 to 15%:

  • Fundamentals of electricity and electronics (5 to 15%)
  • Ground operations and servicing (5 to 15%)
  • Aircraft drawings; weight and balance; fluid lines and fittings
  • Aircraft materials, hardware and processes; cleaning and corrosion control
  • Mathematics; physics for aviation
  • Regulations, maintenance forms, records and publications
  • Inspection concepts and techniques; human factors

The Airframe test spreads 15 areas the same way, from metallic structures to water and waste systems, with metallic structures and airframe inspection at up to 15%. The Powerplant test has 13, from reciprocating engines to propellers, with reciprocating engines and engine electrical systems at up to 15%.

Authorization and the test center

The test center needs proof you’re allowed to test. The matrix accepts one of these:

  • An authenticated document from an FAA-certificated Aviation Maintenance Technician School (AMTS) with its name and certificate number, your graduation date and the curriculum you finished
  • An original FAA Form 8610‑2 completed in block V by the FAA
  • A military Certificate of Eligibility (COE) for the tests it lists
  • For General only, a school document showing you finished the general curriculum

The proctor scans it and hands back the original. You book through PSI Services after getting an FAA Tracking Number (FTN), and the proctor gives you the testing supplement FAA-CT-8080‑4G. PSI says its test centers sit within 25 miles of 93% of part 147 schools, and within 50 miles of 99%.

2025 pass rates

The FAA publishes the number of tests and the pass rate each year. For 2025:

TestTestsPassAverage
AMG: General22,58569.59%74.02%
AMA: Airframe16,88574.01%75.90%
AMP: Powerplant17,57263.04%72.58%

Across every FAA knowledge test in 2025, pilots included, the pass rate was 89.56%.

Your test report and retakes

You get a printed Airman Knowledge Test Report (AKTR) when you finish. For each question you missed it lists an ACS code, and the examiner asks about those subjects in your oral test. Keep the original: you hand it to the examiner. Tests from January 13, 2020 onward can be reprinted free of charge from PSI’s site, the companion guide says.

If you fail, 14 CFR 65.19 lets you retest after 30 days, or sooner with a signed statement from someone holding the certificate and rating you’re after, saying they’ve given you more instruction in each failed subject and think you’re ready. Bring the failed report to the test center.
