EASA Module 13 study guide
EASA Module 13 · Work through your exam, one topic at a time.
EASA Module 13 is the regulatory-law module of the Part-66 aircraft maintenance licence syllabus. It is aimed at certifying staff, maintenance planners, quality and compliance staff, and anyone who needs to work confidently inside the EU continuing-airworthiness system rather than only at the aircraft. The EASA Module 13 study guide has 4 sections and about 1,952 words.
01Aircraft Maintenance and Continuing Airworthiness - Part-66 Licensing
This domain tests Part-66 - the licensing rules that decide who may certify aircraft maintenance and how a licence is obtained, endorsed and kept valid. Questions typically ask you to match a category to its privileges, choose the correct experience route, and explain how type ratings, recent experience and organisation authorisations interact with continuing airworthiness.

Part-147 (Annex IV to Regulation (EU) 1321/2014) approves maintenance training organisations that deliver the basic and type training, and the examinations, that underpin Part-66 licences.
