ExploreAbout this exam
Module 14, Propulsion, is one of the Part-66 aircraft maintenance licence knowledge modules listed in the Annex III appendix to Commission Regulation (EU) No 1321/2014, the regulation that sets out continuing airworthiness requirements including maintenance personnel training and licensing. It is aimed at candidates working toward a Part-66 licence, typically through a Part-147 training organisation or by self-study followed by examination at a competent authority. The module is delivered in English as multiple-choice questions across four subject areas: turbine engines, piston engines, engine systems and components, and propellers. Content spans engine construction and operating principles, ignition, starting, fuel, lubrication, cooling, indicating and control systems, plus propeller theory, construction, control and synchronising. Preparation works best in the order the syllabus is written: build turbine and piston fundamentals first, because the systems and propeller sections assume them, then move to systems and finally propellers. Work through each subject area against the regulation's appendix, practise multiple-choice questions under time pressure, and revisit weak areas rather than rereading whole chapters.

What you'll study
About EASA Module 14 preparation
Is Module 14 the same for every Part-66 licence category?
No. The appendix to Commission Regulation (EU) No 1321/2014 sets out the knowledge modules and their applicability per licence category, so the propulsion content required for a given category is defined by that appendix, not by this page. Check the regulation text and your training organisation's syllabus for the exact scope that applies to you.
How many questions are on the Module 14 exam and how long is it?
This page cannot confirm a question count, duration, or pass mark. Those administrative values were not verifiable from the retrieved source, and they are set by the examining competent authority or Part-147 organisation rather than by the module syllabus. Confirm the format, timing and passing score directly with your examination provider before you book.
Can I retake Module 14 if I fail, and how soon?
Retake policy is not stated in the retrieved source, so no interval or attempt limit can be quoted here. Retake rules are set by the competent authority or the Part-147 organisation delivering the examination. Ask your provider about attempt limits, waiting periods and any required additional training before a second attempt, and get the answer in writing before your first sitting.
How long does a Module 14 result stay valid?
The retrieved source did not provide a validity period for module examination results, so none is quoted here. Validity of module credits toward a Part-66 licence application depends on the applicable regulation and the accepting authority's practice. Because these rules are revised periodically, verify the current position with your competent authority rather than relying on older study notes.
Which subject area should I study first?
Start with turbine and piston engine fundamentals, since the systems and propeller areas assume that groundwork. Move to engine systems and components next, then propellers. Within each area, work from construction and principles through to operation and indications. Finish with mixed-topic practice questions so you meet propulsion topics in the shuffled order an exam presents them.
How difficult is Module 14 compared with other modules?
Difficulty is subjective and no comparative data was available from the source. Propulsion rewards understanding rather than memorisation: candidates who can explain why a system behaves as it does tend to handle unfamiliar wording better than those who only recall lists. Expect detailed questions on component function, control and indication, and allow more revision time for the systems area.
What are the most common ways candidates lose marks?
Typical failure modes are confusing similar-sounding components across turbine and piston engines, mixing up propeller control terminology, and answering from memory of older study material instead of the current syllabus. Another frequent problem is not practising under time pressure. Read each question for the specific system named, eliminate options that belong to the other engine type, and review every wrong answer against the syllabus.
Does this page replace the regulation or an approved training course?
No. This is independent study material and is not affiliated with EASA or any authority. The authoritative scope is the appendix to Commission Regulation (EU) No 1321/2014, and practical training requirements come from your Part-147 organisation. Use this page for practice and orientation, and confirm all administrative details with your provider.
