FAA A&P Powerplant exam requirements & cost
Straight from the certifying body — separate from what we charge for the study portal.
The FAA Aviation Mechanic Powerplant knowledge test has 100 multiple-choice questions and a 120-minute time limit, drawn from the Airman Certification Standards (FAA-S-ACS-1). The minimum passing grade is 70 percent (14 CFR 65.17), and the content spans 13 areas, led by Reciprocating Engines (11%). This portal's practice mock has 100 questions; the FAA oral and practical tests are separate. The minimum passing grade for each FAA test is 70 percent (14 CFR 65.17). The FAA does not set the fee: a 2022 testing-center schedule listed about $175 for a powerplant knowledge test and the FAA describes such fees as approximate, so confirm the current price with your test center. The content outline spreads questions across 13 areas; the largest are Reciprocating Engines (11.0%); Turbine Engines (9.0%); Engine Electrical Systems (9.0%). The full list of areas and weights is on the portal exam page. To earn a mechanic certificate you must be at least 18, read, write, speak and understand English, and have 18 months of practical experience per rating (30 months for both) or graduate from an FAA-certificated maintenance technician school (14 CFR 65.71 and 65.77).
