FAA FAA Airman and Aviation Certificates License: Complete Roadmap
Follow this path to organize your licensing and exam preparation
Master Reciprocating and Turbine Engine TheoryYou are here
Start with the two largest subject areas: four-stroke cycle, valve timing, detonation, plus axial/centrifugal compressors, combustion, and the turbine section.
Add Ignition, Propellers, and Fuel Systems
Work magneto theory and turbine ignition, constant-speed and feathering propellers, carburetors, fuel injection, and fuel control units.
Cover Support Systems and Instruments
Study lubrication, electrical, induction/cooling, and engine instrument systems including manifold pressure, EGT, and CHT.
Finish Inspection, Overhaul, Fire, and Exhaust
Train inspection procedures, ADs, removal/installation/overhaul, fire protection, and exhaust/reverser systems under timed mixed sets.
Can You Take the FAA AMT Powerplant Exam?
Check if you meet the basic eligibility requirements
- •Be able to read, write, speak, and understand English
- •Meet the experience or schooling requirements of 14 CFR 65 for the powerplant rating
- •Pass the powerplant knowledge test before the oral and practical tests
- •Knowledge test is administered by PSI on the FAA airman testing system
