Why this guide
- Built directly from FAA-S-ACS-1 — the same Aviation Mechanic Certification Standards the FAA references in 14 CFR § 65.75(a), so every topic maps to the AMG/AMA/AMP tests
- Three tests in one guide — the General, Airframe, and Powerplant written exams cover 9 General, 15 Airframe, and 13 Powerplant subject areas; we keep them organized by rating so you study only what you need
- Maintenance paperwork decoded — 14 CFR Part 43, maintenance entries, AD tracking, 337 Major Repair & Alteration, and return-to-service language that trips up oral exams
- Print-friendly — full guide for deep study, two cheat sheets for module review, pocket crib sheet for the hangar or the testing center
Who this is for
- Aviation Maintenance Technician students in an FAA-approved Part 147 school
- Military aircraft maintainers converting to civilian A&P certification
- Line mechanics studying for the AMG, AMA, and AMP knowledge tests
- Self-study applicants who need the ACS subject areas in plain English
- Anyone preparing for the oral and practical under 14 CFR § 65.79
What you'll learn
- General (AMG — 60 questions, 70%): fundamentals of electricity and electronics, aircraft drawings, weight and balance, fluid lines and fittings, materials/hardware/processes, ground operations and servicing, cleaning and corrosion control, mathematics, regulations/maintenance forms/records/publications, physics for aviation, inspection concepts, and human factors
- Airframe (AMA — 100 questions, 70%): metallic and non-metallic structures, flight controls, airframe inspection, landing gear systems, hydraulic and pneumatic systems, environmental systems, aircraft instruments, communication and navigation systems, fuel systems, electrical systems, ice and rain control, rotorcraft fundamentals, water and waste systems
- Powerplant (AMP — 100 questions, 70%): reciprocating and turbine engines, engine inspection, engine instruments, fire protection, engine electrical systems, lubrication systems, ignition and starting systems, fuel and fuel-metering systems, induction and cooling systems, turbine engine air systems, exhaust and reverser systems, propellers
- Oral & practical risk areas: human factors, non-destructive inspection, AD compliance, return-to-service documentation, and tool calibration
- Regulatory backbone: 14 CFR Part 65 Subpart D, Part 43 maintenance/inspection/alteration, and the mechanic ACS incorporated by reference in § 65.75(a)
- Quick math and memory items: torque conversions, rivet identification, electrical wire sizing, hydraulic Pascal’s law, and propeller theory
What you're getting
- 6 printable PDFs: cover, course notice, full study guide, two condensed cheat sheets, and an exam-day pocket card.
- Content built from the public syllabus and real test-taker accounts.
- No fake "actual exam" content — honest, source-cited study aids.
"The General test feels easy but has trick questions on electricity and corrosion — know your series/parallel circuits and anodizing."
