What are EASA Part66 study notes?
Our EASA Part66 study notes are complete written learning material for the theory behind all 17 basic-knowledge modules. They are organised the same way the exam is — by EASA syllabus paragraph — so you learn exactly what you will be tested on, for licence categories A, B1, B2, B2L and B3.
Where the practice quizzes test what you know, the notes are where you learn it in the first place: clear explanations, worked examples, formulas and technical diagrams for every topic on the syllabus — 900+ pages in total, written specifically to get you above the 75% pass mark.
In short
One-time purchase, lifetime access to comprehensive notes for every EASA Part66 module — the theory companion to your practice questions. The first paragraph of every module is free, so you can read the real thing before you buy.
What's inside every module
These are not slideshow bullet points. Each module is written out in full, the way a good instructor would explain it — with everything you need to actually understand the topic:
Mapped to the syllabus
Organised paragraph by paragraph against the official EASA Part66 syllabus, so nothing on the exam is missed.
Worked examples
Step-by-step worked examples in dedicated example boxes, so calculations and procedures actually click.
Formulas done properly
Every formula is typeset and rendered cleanly, not squashed into plain text — easy to read and remember.
Diagrams & tables
Technical diagrams and comparison tables throughout, so systems and relationships are easy to picture.
Exam tips & pitfalls
Tip and warning callouts flag the things examiners love to catch people out on.
900+ pages, all 17 modules
Comprehensive coverage of the full syllabus in one place, kept up to date with the current regulations.
How the notes are structured
Every module is broken down the same way as the official syllabus — one note per syllabus paragraph. That means you can study in exactly the order you will be examined, jump straight to a weak topic, and always know which syllabus reference you are looking at.
Paragraph by paragraph
Pick a module, see its syllabus paragraphs, open any one and read the full note for that topic.
Free preview, every module
The first paragraph of all 17 modules is unlocked — read real notes before you decide to buy.
Notes + questions = complete exam prep
Passing EASA Part66 exams takes two things: learning the theory and practising exam-style questions until you are consistently above 75%. The study notes give you the theory; our quiz subscription and question bank give you the practice. Together they cover the whole journey — understand it, then prove it.

EASA Part66 study notes — frequently asked questions
What are EASA Part66 study notes?
They are complete written learning material covering the theory of all 17 EASA Part66 modules, organised by EASA syllabus paragraph. They explain each topic in full — with worked examples, formulas, diagrams and exam tips — to prepare you for the aircraft maintenance licence exams in categories A, B1, B2, B2L and B3.
Which modules and licence categories do the notes cover?
All 17 basic-knowledge modules are covered, across licence categories A, B1, B2, B2L and B3. You get every module in one purchase, so the notes work whichever category you are studying for.
Can I preview the notes before I buy?
Yes. The first paragraph of every one of the 17 modules is free to read, so you can see the real depth and style of the notes before deciding to buy. No payment is needed to preview.
What is the difference between Online Access and the Offline PDF?
Online Access (€99.99) lets you read all notes in your browser on any device, always kept up to date, and needs a free account. The Offline PDF (€299.99) is a downloadable 900+ page, print-friendly, bookmarked PDF you can study without internet and without an account. Both are one-time purchases.
Do I also need a quiz subscription?
They serve different jobs. The study notes are where you learn the theory (a one-time, lifetime purchase); the quiz subscription is where you practise exam-style questions. Many members use both — notes to understand each topic, questions to test that they are above the 75% pass mark.
Are the study notes kept up to date with the current EASA syllabus?
Yes. The notes are written against the current EASA Part66 syllabus and maintained as the regulations change, so you are always studying the material that reflects the exam.
