Frequently Asked Questions
How many questions are on the FAA AMG General knowledge test?
The official FAA Aviation Mechanic General (AMG) knowledge test has 60 multiple-choice questions. This free practice bank provides 100 selected-response items so you can drill every subject area with extra repetition before test day.
What score do I need to pass the AMG test?
You must score at least 70 percent on the FAA AMG knowledge test to pass. The test is computer-based and administered by PSI at FAA-approved knowledge testing centers, and you receive an airman knowledge test report with your result.
How much time do I get and how much does it cost?
You are allowed 2 hours for the 60-question AMG test, and the PSI testing fee is approximately $175. The Airframe and Powerplant knowledge tests are separate tests with their own fees, so plan the budget for each one you need.
Is the General test the same as the Airframe and Powerplant tests?
No. The General (AMG), Airframe, and Powerplant knowledge tests are three distinct FAA airman knowledge tests. The General test covers subjects common to both ratings, and you must pass the General plus the Airframe and/or Powerplant tests before the oral and practical exams.
What are the eligibility requirements to take the AMG test?
Under 14 CFR Part 65, you must be at least 18 years old, be able to read, write, speak, and understand English, and document the required practical experience or graduate from an FAA-certificated Part 147 aviation maintenance technician school.
Did the FAA AMG test change for 2026?
As of May 16, 2026, the AMG knowledge test remains 60 multiple-choice questions with a 2-hour limit and a 70 percent passing score, delivered by PSI. Subject areas continue to follow 14 CFR Part 65 and the FAA-S-ACS-1 Airman Certification Standards.
