Passing the Aircraft Mechanic Written Test

What to expect when taking the three written test.

 

Our three rules for taking and passing the FAA's mechanic written test are STUDY, STUDY, STUDY.

You may have years of practical experience working on airplanes, however in the three written test, chances are you will encounter questions on subjects that are totally new to you. If you are retiring from the military you probably have had little experience with reciprocating engines (a major portion of the written test). We highly recommend that you consider taking a refresher or prep course, (Recommended Schools).

Description of the test

The three test, (General, Airframe and Powerplant) are multiple-choice type. The minimum passing score is 70 percent on each of the 3 test. The General test contains 60 questions, and the Airframe and Aviation Powerplant tests contain 100 questions each. You are allowed 2 hours to complete each of the written test.

If you do not pass and wish to retest. You may retake the test after 30 days, or sooner if you receive additional instruction from a person holding a certificate in the rating you seek. You must present a signed statement from the person holding the certificate to retest.

Quoted from the FAA

"Due to a large number of maintenance-related aviation accidents and incidents that occurred in the late 1980s and early 1990s, Transport Canada identified twelve human factors that degrade people's ability to perform effectively and safely, which could lead to maintenance errors. These twelve factors, known as the "dirty dozen," were eventually adopted by the aviation industry as a straight forward means to discuss human error in maintenance. It is important to know the dirty dozen, how to recognize their symptoms, and most importantly, know how to avoid or contain errors produced by the dirty dozen. Understanding the interaction between organizational, work group, and individual factors that may lead to errors and accidents, AMTs can learn to prevent or manage them proactively in the future."
