Part-66 Module 10 · Work through your exam, one topic at a time.
This page covers Module 10 - Aviation Legislation, the regulatory knowledge module of the EASA Part-66 aircraft maintenance licence syllabus. It is a common module, sat by candidates working towards the licence categories, and it is often one of the first hurdles, because everything that follows assumes you know who is allowed to do what, and on whose authority. The Part-66 Module 10 study guide has 7 sections and about 2,036 words.
