Practice Tests for Each FAA A&P Exam
FAA General Knowledge Test Practice
The General test (ACS subject area AM.I) is the foundation every candidate passes first. It covers basic electricity, aircraft drawings, weight & balance, materials and processes, physics and mathematics, FAA regulations, and ground operations. The real exam is 60 questions in 2 hours with a 70% pass mark, and the General test is included free on the SkyLicense Free plan.
FAA Airframe Knowledge Test Practice
The Airframe test (ACS subject area AM.II) covers aircraft structures and airframe systems: metallic and composite structures, hydraulic and pneumatic systems, landing gear, flight controls, fuel systems, cabin atmosphere, fire protection, and aircraft electrical systems. The real exam is 100 questions in 2 hours with a 70% pass mark.
FAA Powerplant Knowledge Test Practice
The Powerplant test (ACS subject area AM.III) covers aircraft engines and related systems: reciprocating and turbine engines, propellers, fuel metering, ignition and starting, lubrication, cooling, exhaust, and engine electrical systems. The real exam is 100 questions in 2 hours with a 70% pass mark.

What is the FAA A&P practice test?
An FAA A&P practice test is a timed, multiple-choice simulation of the FAA mechanic knowledge exams. SkyLicense offers practice tests for all three exams required for the Airframe & Powerplant (A&P) certificate: General (60 questions, 2 hours), Airframe (100 questions, 2 hours), and Powerplant (100 questions, 2 hours). Every test must be passed with a score of 70% or higher.
How many questions are on each FAA A&P knowledge test?
The FAA General knowledge test has 60 questions, the Airframe knowledge test has 100 questions, and the Powerplant knowledge test has 100 questions. Each test allows 2 hours and requires a passing score of 70% — 42 correct on General and 70 correct on Airframe or Powerplant.
What score do you need to pass the FAA A&P written exams?
You need a score of 70% or higher on each FAA mechanic knowledge test. The three tests are General (60 questions, 42 correct to pass), Airframe (100 questions, 70 correct to pass), and Powerplant (100 questions, 70 correct to pass).
Where do you take the real FAA A&P knowledge tests?
The real FAA A&P knowledge tests are computer-based and taken at FAA-approved testing centers operated by the FAA knowledge testing service, PSI. You schedule your tests through PSI after completing an FAA Form 8610-2 application. SkyLicense practice tests replicate the same format so you are ready on test day.
Are SkyLicense practice questions aligned with the real FAA ACS?
Yes. Every SkyLicense practice question is mapped to the Aviation Mechanic Airman Certification Standards (FAA-S-ACS-1) — subject area AM.I for General, AM.II for Airframe, and AM.III for Powerplant. This means you practice exactly the topics, depth, and question style used on the real exams.
Can I retake a failed FAA A&P knowledge test?
Yes. You must wait at least 30 days before retaking a failed FAA knowledge test. Your passing knowledge test results are valid for 24 months, during which you must complete the oral and practical (O&P) exam with a Designated Mechanic Examiner (DME).
