About this test

Practice for the FAA Aviation Mechanic Powerplant (AMP) knowledge test with original questions written from the FAA Aviation Maintenance Technician Handbook – Powerplant (FAA-H-8083-32B) and the current text of 14 CFR Part 43 on eCFR. Every correct answer is backed by a passage of the source and checked by two independent verifiers.

Study: every question with a short explanation.
Topic drills: reciprocating engines, turbine engines, fuel metering, induction and exhaust, ignition and starting, lubrication and cooling, propellers, inspection and regulations.
Mock test: 100 questions, 70 correct (70%) to pass, as the FAA Airman Knowledge Testing Matrix (revised 9/25/26) states for test AMP.

The questions are written in our own words; this is not the FAA’s question bank. Chart, figure and computer questions that need images are not included.
