ExploreAbout this exam
Module 7 - Maintenance Practices is one of the knowledge modules that make up the EASA Part-66 aircraft maintenance licence syllabus. Its regulatory home is Commission Regulation (EU) No 1321/2014 on continuing airworthiness, adopted on 26/11/2014 and published in the Official Journal under reference OJ L 362, 17.12.2014, p. 1. That regulation has been amended repeatedly, most recently - on the EASA document-library page consulted - by Commission Implementing Regulation (EU) 2026/100, so the version you study against matters. Module 7 is aimed at trainee and practising certifying staff who need to show they can work safely and correctly on real hardware, not just recite theory. The syllabus spans ten areas: aircraft and workshop safety precautions; workshop practices; tools; engineering drawings, diagrams and standards; fits and clearances; EWIS and electrical cables; riveting, pipes and hoses, springs, bearings, transmissions and control cables; material handling, welding, brazing and soldering; aircraft weight and balance, handling and storage; and disassembly, inspection, repair, assembly and maintenance procedures. Prepare with the current regulation text and accepted means of compliance, your part-147 or equivalent course notes, and hands-on workshop familiarity. Note that examination parameters such as question count, time allowed, pass mark, fees and retake rules are not stated on the regulation page cited here; confirm them with your competent authority or approved training organisation.

What you'll study
About EASA Module 7 preparation
What format does the Module 7 exam take?
Part-66 knowledge examinations are multiple-choice. The number of questions, the time allowed and the pass mark are set by the competent authority and are not published on the EASA regulation page cited here, so check your national authority's examination rules or ask your training organisation before you book.
How long is the exam and how many questions are there?
We cannot give a figure. The document-library page for Commission Regulation (EU) No 1321/2014 states the adoption date, Official Journal reference, amending regulations and repealed regulations only - no examination parameters. Treat any specific question count or duration you see elsewhere as needing verification against an official source.
What score do I need to pass?
The pass mark is not stated in the cited source and is therefore left blank here rather than guessed. Passing standards are set out in the examination rules applied by the competent authority, so confirm the current figure with them or with your approved training organisation before relying on it.
Can I retake the exam, and how soon?
Retake policy is not covered by the source consulted, so no number of attempts or waiting period is given on this page. Retake rules vary and are set by the competent authority or the examination body; check their published procedure rather than planning around an assumed figure.
Which topics should I study first?
Start with safety precautions and workshop practices, because they underpin everything else, then move to tools, drawings and fits and clearances. Those four feed directly into the practical topics - EWIS, riveting, pipes and hoses, bearings and transmissions - and into weight and balance and maintenance procedures.
How much calculation is involved?
Expect arithmetic rather than advanced mathematics: fits and clearances, tolerance stacks, weight and balance moments, and simple electrical relationships. Practise setting out your working neatly, because sign and unit errors - millimetres against inches, or a moment arm measured from the wrong datum - are the usual cause of lost marks.
What are the most common failure modes?
Candidates typically lose marks on safety-related detail (fuel-tank and pressurised-system precautions), on EWIS identification and separation rules, and on torque and clearance limits that they half-remember. Learn limits from a current source rather than from memory, and revise the topics you find least interesting, since those attract the most careless errors.
Do I need to memorise the regulation itself?
No. Module 7 examines maintenance practice, not the text of Commission Regulation (EU) No 1321/2014. You should, however, know that the regulation is the regulatory basis and that it is amended frequently - the EASA page lists amendments up to Commission Implementing Regulation (EU) 2026/100 - so always work from current documentation.
Where can I check whether the regulation has changed?
The EASA document library page for Commission Regulation (EU) No 1321/2014 lists the adoption date, the Official Journal reference, every amending regulation and the regulations it repeals. Use it to confirm you are studying against the current version, and re-check it before an exam sitting.
