FAA A&P Practice Test: General, Airframe & Powerplant Study Lab
Practice the General, Airframe, and Powerplant knowledge areas, rehearse your oral answers, and turn missed AKTR ACS codes into a focused study plan. Everything runs in your browser, and your progress stays on this device.
This is not a leaked-question bank wearing a fake mustache. The questions are independently written from the FAA Mechanic ACS, FAA maintenance handbooks, regulations, and other public FAA material.

What the FAA A&P testing process actually looks like
The FAA mechanic certificate has two ratings: Airframe and Powerplant. Holding both is commonly called an A&P certificate. FAA eligibility generally comes through an FAA-certificated Aviation Maintenance Technician School, qualifying practical experience, or certain military pathways. For the practical-experience route, the regulation requires at least 18 months for one rating or 30 months of concurrent experience for both. 14 CFR § 65.77 has the controlling language.
| Test | Code | Questions | Time | Passing score |
|---|---|---|---|---|
| General | AMG | 60 | 2 hours | 70% |
| Airframe | AMA | 100 | 2 hours | 70% |
| Powerplant | AMP | 100 | 2 hours | 70% |
The FAA says applicants take the General knowledge test first, followed by Airframe and/or Powerplant. The current FAA testing matrix lists the question counts, two-hour time limits, and 70-percent passing score shown above. Validation questions may also appear, but they do not count toward the score. FAA Mechanic Testing links the current matrix and testing resources.
All prescribed tests normally must be passed within a 24-month period under 14 CFR § 65.71. There is a narrow regulatory relief provision for qualifying U.S. military and civilian personnel assigned outside the United States in support of U.S. Armed Forces operations, so do not treat the 24-month rule as a one-sentence universal with no exceptions.
The part people underestimate: oral and practical testing
The written tests are only one layer. After passing the applicable knowledge tests, a candidate normally goes to a Designated Mechanic Examiner (DME) for oral and practical testing. Under the current Mechanic Test Generator system, the FAA organizes separate General, Airframe, and Powerplant oral and practical tests.
The FAA's Mechanic Test Generator FAQ says each oral test has a minimum of four randomly generated questions even with a perfect AKTR. Missed ACS codes on the written report add oral questions that target those deficient areas. It is the code that matters: multiple missed written questions carrying the same ACS code add one additional oral question for that code.
The practical side is even less compatible with rote memorization. FAA guidance specifies 9 General, 11 Airframe, and 11 Powerplant practical projects. Each project is standalone and includes two practical questions tied to the task. That is why this lab rehearses explanation, troubleshooting, data selection, and risk thinking but does not pretend a browser can grade safety wire, sheet-metal work, a compression check, or your ability to keep your hands attached to your body.
The 40 ACS subject areas
The Aviation Mechanic ACS organizes testing across 12 General subjects, 15 Airframe subjects, and 13 Powerplant subjects. Use the study map below to identify broad weak areas, then drill into the exact knowledge, risk-management, and skill elements in your current copy of FAA-S-ACS-1.

Still need the training itself?
Practice helps after you have something real to practice
If electrical schematics, structures, turbine theory, hydraulics, and maintenance data all look like alien scripture, structured hands-on training may be more useful than grinding flashcards harder.

How to use this study lab without studying like a raccoon with a Quizlet account
- Start with the diagnostic. It samples all three sections and gives you a quick weakness map.
- Drill weak ACS subjects. Immediate explanations are better when you are learning; exam mode is better when you are checking readiness.
- Practice saying answers out loud. Recognition is easier than recall. O&P prep should force you to explain what you would do and why.
- Use your AKTR after a real knowledge test. Enter only the missed ACS codes, not personal information. Build the remediation list before you meet the DME.
- Use current technical data. If a question depends on aircraft-specific torque, pressure, limit, cable tension, dimension, or procedure, the right habit is to find the applicable data, not memorize somebody else's airplane.

FAA A&P practice test FAQ
How many questions are on the FAA A&P written tests?
The current FAA testing matrix lists 60 scored questions for General (AMG), 100 for Airframe (AMA), and 100 for Powerplant (AMP). Each test has a two-hour allotted time and a 70-percent passing score. FAA test sessions can include additional unscored validation questions.
Does this tool use actual FAA or PSI test questions?
No. The practice bank is written independently from public FAA regulations, handbooks, and ACS material. It is designed to test the same kinds of knowledge without pretending to possess active FAA/PSI exam items.
How does my AKTR affect the oral exam?
FAA Mechanic Test Generator guidance says missed ACS codes on your AKTR add oral questions targeting those deficient areas. If several missed written questions share the same ACS code, that code adds one additional oral question rather than one question for every missed item.
What if I fail a knowledge, oral, or practical test?
Under 14 CFR § 65.19, you can normally retest after 30 days. Earlier retesting is allowed when you present the required signed statement from an airman holding the certificate and rating you seek, confirming additional instruction in the failed subjects and readiness to retest.
Can I learn the practical test online?
You can prepare the cognitive side online: technical-data navigation, troubleshooting logic, oral explanation, safety planning, and system theory. You cannot learn or prove hands-on maintenance competency from a browser alone. Practical skill requires real equipment, tools, supervision/training, and ultimately evaluation by the DME.
