airMaintenance Update - Open Book
2010 Annual Training Exam
AirMaintenance Update is Trasnsport Canada-approved for recurrent training. This is our Eighth exam, which is also published in our anniversary issue, in accordance with our agreement with Transport Canada. The exam consists of questions based on articles appearing in all six issues from the past year. You will require all six issues in order to write the exam. If you are missing any issues, call us at (604) 214-9824 or email us at amu.magazine@telus.net, or order online from this website under "order back issues", and we will mail them to you at a cost of $6.95 per magazine postpaid. A 75% pass rate is required in order to qualify for your 16 hours towards RT: The questions in this exam are arranged in order of their appearence in AirMaintenance Update according to issue and individual article. The exam can also be accessed and printed from this website. Answers must be drawn directly from the text of the articles in order to be considered correct. Completed exams should be received no later than October 31, 2010. We will mark your test and return it along with documentation supporting your submission. We will keep a copy of your written test results on file for future reference, and a copy will be forwarded to Transport Canada. -- GOOD LUCK TO ALL PARTICIPANTS--
