FAA Airframe Mechanic Certification Exam Overview

The FAA Airframe Mechanic written exam tests your knowledge of aircraft structures and systems required to earn an Airframe certificate under 14 CFR Part 65. The written test consists of 60 questions and you have 2 hours to complete it. A passing score of 70% or higher is required.

The Airframe certificate covers everything from fuselage construction and wing structures to empennage assemblies and control surfaces. Unlike the Powerplant rating, which focuses on engines and propellers, the Airframe rating covers the aircraft body, skin, and associated systems including hydraulics, pneumatics, and flight controls.

Candidates must be at least 18 years old, able to read, write, speak, and understand English, and demonstrate 18 months of practical experience — or present evidence of graduation from an FAA-certificated Aviation Maintenance Technician School (AMTS).

Key Airframe Knowledge Areas

The FAA Airframe written exam draws from the Aviation Mechanic Airframe knowledge test guide (FAA-G-8082-11). Questions cover aircraft covering and structural repair using fabric, aluminum sheet metal, fiberglass, and advanced composites. You must understand inspection procedures, including 100-hour and annual inspections, condition inspections, and progressive inspection programs.

Hydraulic and pneumatic systems are heavily tested. Expect questions on actuating cylinders, hydraulic pumps, reservoirs, accumulators, and priority valves. Pneumatic systems for landing gear, brakes, and deicing are also included. Weight and balance questions require you to calculate CG location after adding or removing equipment.

Aircraft assembly and rigging covers control surface alignment, cable tension, and the use of rigging fixtures and tools. The welding section tests knowledge of oxyacetylene, MIG, and TIG processes as applied to airframe repair under approved data.

How to Use This Practice Test PDF

Print the PDF and work through the questions in a timed setting — allow yourself 2 minutes per question to simulate real exam conditions. After completing each section, review the answer explanations to reinforce your understanding of the underlying FAA regulations and technical standards.

Cross-reference incorrect answers with the Aviation Maintenance Technician Handbook – Airframe (FAA-H-8083-31) and the relevant Advisory Circulars. Repeat the practice test until you consistently score above 80% before scheduling your official knowledge test at an FAA-approved testing center.
