FAA community advisory
As of October 26, 2026, the FAA still requires three separate aviation mechanic knowledge tests: AMG General (60 questions), AMA Airframe (100), and AMP Powerplant (100), with 2 hours allotted for each and a 70% passing score on each test. The FAA does not publish a single fixed AMT knowledge-test price on its mechanic page and instead directs applicants to PSI for current fees; certain JSAMTCC/MOA-eligible military applicants may test at no cost. FAA-S-ACS-1 (November 2021, effective September 21, 2022) remains the mechanic ACS; since April 2026 the AMT General, Airframe, and Powerplant knowledge tests feature questions with embedded images, and the FAA expects modifications from PSI's assessment of the AMT tests in 2027.

About the FAA A&P Mechanic Exam
The FAA A&P mechanic path combines the Aviation Maintenance Technician General, Airframe, and Powerplant knowledge tests that feed into the oral and practical certification process. The written tests cover core maintenance math and electricity, aircraft structures and systems, and reciprocating/turbine powerplant inspection, operation, and troubleshooting.
Exam sponsor: FAA / PSI. The requirements and fees below concern the certification or admission exam, separate from our free practice resources.
Assessment
3 separate knowledge tests: AMG General (60), AMA Airframe (100), AMP Powerplant (100)
Time Limit
2 hours per test (6 hours total)
Passing Score

FAA A&P Mechanic: Suggested Study Strategy
Frequently Asked Questions
How is the FAA A&P knowledge testing path structured?
The FAA mechanic path uses three separate multiple-choice knowledge tests: AMG General, AMA Airframe, and AMP Powerplant. You must pass the applicable knowledge test or tests before moving to the oral and practical exams with a Designated Mechanic Examiner.
What score do I need to pass the FAA A&P written exams?
You need 70% on each individual knowledge test. The current FAA testing matrix lists AMG at 60 questions, AMA at 100 questions, and AMP at 100 questions, with 2 hours allotted to each test.
What are the eligibility requirements for the FAA A&P mechanic certificate?
The FAA says applicants must be at least 18 years old and able to read, write, speak, and understand English. You must also qualify by experience or training, such as 18 months for a single rating, 30 months of concurrent airframe and powerplant experience, graduating from an FAA-approved AMTS, or using the JSAMTCC military pathway.
How much does the FAA A&P knowledge testing path cost?
The FAA mechanic page states that AMT knowledge tests are administered through commercial FAA-approved testing centers and directs applicants to PSI for current fees. The same page also notes that some JSAMTCC/MOA-eligible military applicants may take the AMT knowledge tests at no cost.
What changed for FAA mechanic testing in 2026?
Since April 2026 the AMT General, Airframe, and Powerplant knowledge tests feature questions with embedded images; the printed testing supplement stays available until the FAA sets a removal date. The FAA also updated the practical test projects: General activated April 20, 2026, Airframe was scheduled for July 20, 2026, and Powerplant was in final review in the September 2026 advisory. FAA-S-ACS-1 is still the mechanic ACS, and changes from PSI's assessment of the AMT knowledge tests are expected in 2027.
How long should I study for the FAA A&P written exams?
The FAA publishes no study-hour estimate, so plan from your own background. Each test is scored separately (General 60 questions, Airframe 100, Powerplant 100, 70% on each), and the FAA says many AMT test questions are based on content from its AMT General, Airframe, and Powerplant handbooks.
