A&P written test prep

Pass the A&P General written. Study on your phone.

Short lessons and practice questions built from the FAA handbooks. Every answer shows the FAA page it came from, so you can check it yourself.

20 questions. About 10 minutes. No sign-up.

Who it's for

Built for mechanics who learned on the job

You already turn wrenches. The written test asks you to explain the why, in FAA words. That is the part we help with.

Work experience

18 months on airframes or powerplants, or 30 months on both. See what counts.

Military

Aircraft maintainers who served can use that time. The military route.

Tired after a shift

One question at a time on your phone. Ten minutes still counts.

How it works

Three steps to the General written

  1. Check that you qualify

    Answer a few questions about your experience. Use the 8610-2 checker.

  2. Find your weak spots

    20 questions, scored by subject. Take the free diagnostic.

  3. Study what the test asks

    Lessons and practice for all 12 General subjects, expected Q1 2027. See the course.

What makes it different

  • Every answer cites the FAA page it came from.
  • Plain words first. The exact FAA terms come next.
  • A licensed A&P/IA checks every question before we mark it reviewed.
  • Spot an error? We fix it and log it on the errata page.

The FAA's numbers

Where people lose points on the General

The FAA publishes which subjects test takers miss most. Two General subjects top the list. The diagnostic weights both.

78.5%

AM.I.G.K6

missed on corrosion identification and inspection

74.9%

AM.I.A.K24

missed on static discharge (ESD)

69.6%

General written

passed in 2025. About 3 in 10 failed.

Missed rates are from the FAA's most-missed report for July 2024 through June 2025. The A&P tests have the lowest pass rates among FAA tests with over 1,000 takers. [FAA-FMC-CY2025-Q2, CY25 Q2, p. 1] [FAA-AKT-VOL-CY2025, CY2025, p. 1]

Questions

Straight answers

Is SafetyWire approved by the FAA?

No. The FAA does not approve study courses, ours included, and we are not affiliated with the FAA. What we do is build every lesson and question from public FAA documents and show you the page each answer came from.

Does studying here count toward my experience or school hours?

No. Your eligibility comes from 18 or 30 months of work experience, or from a Part 147 school. SafetyWire helps you pass the written tests once you are eligible.

When does the course open?

The General (AMG) course is expected Q1 2027. The guides, the eligibility checker and the free diagnostic are open now.
