The written tests

A full A&P certificate requires the three mechanic written tests plus the oral & practical — start with General, it is required for both ratings. The Part 107 Remote Pilot certificate needs only its own knowledge test. The Inspection Authorization comes later: 14 CFR 65.91 asks for an A&P held three years and two years of recent experience before you may even apply to sit it.

Why Hangar Prep?

Every question cites its source — the FAA handbook chapter or the 14 CFR section — in a plain-English explanation, so you learn the why, not just the answer. Revision Mode shows you the answer and its explanation the moment you choose, and resurfaces the questions you have missed first. Exam Mode scores you knowledge-area by knowledge-area like the real AKTR, timed if you wish, and keeps your history on your device. Pay once for lifetime access to every test on the site. No subscription. No account.
