Powerplant Test Guide 2021: Pass your test and know what is essential to become a safe, competent AMT from the most trusted source in aviation training (ASA Fast-Track Test Guides) 2021st Edition

Perfect book to help study

Good source of info, especially for Os & Ps. Not 100% accurate but worth the buy if you like hard copies. The phone app is the better option in my opinion... some people rely solely on this others say yo read the 8083s it just depends on what version of the FAA test you get dealt. But you can definitely get buy just using Prepware.

It's nice that I got the book for way cheaper that what my school charges but I needed the software too not just the test. Bummer.

Good book
