The hangar teaches the job.
The exams test the theory.

Up to 17 modules, each with its own multiple-choice exam and a 75 % pass mark.

The official material runs to thousands of pages, and the exam asks for exact answers: a number, a name, the one word that makes the difference.

These notes keep what each syllabus asks for, then make you practise it.

Exam trap!

Underload is safe because the task is easy.

False. Boredom leads to complacency and missed defects. Every module flags traps like this one in red.

Every fact checked against the official syllabus

Built on the EASA Part-66 syllabus (September 2025 edition), the FAA maintenance handbooks and the official accident reports. If you find an error, tell us: you get the corrected file for free.

Made by someone who went through it

I did my aircraft maintenance training too. The hangar was fine. The theory was the hard part, and we had to write our own notes.
