About this test

Practice for the FAA Aviation Mechanic Airframe (AMA) knowledge test with original questions written from the FAA Aviation Maintenance Technician Handbook – Airframe (FAA-H-8083-31B) 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: structures and assembly, hydraulic, pneumatic and fuel systems, landing gear, electrical, instruments and communication, ice, rain, fire and cabin systems, 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 AMA.

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.
