What we are — and what we are not
What we are
- An independent study and self-assessment platform for the EASA Part-66 licence examinations.
- A question bank, a set of written study notes, and aircraft type-rating banks, sold directly to engineers.
- A provider of EASA continuation-training courses with issued certificates.
What we are not
- Not a Part-147 approved maintenance training organisation. We do not run approved courses or sit official examinations.
- Not affiliated with EASA, the UK CAA, or any national aviation authority.
- Not a substitute for the experience and training your competent authority requires.
Your official examination is sat with your competent authority or an approved Part-147 organisation. What we do is make sure that when you get there, you have already answered the questions.
How our material is made
Every question in the Part-66 bank carries a written explanation grounded in the syllabus, shown the moment you answer. Those explanations are not published as drafted: each one is independently re-checked against the marked-correct answer, and anything that cannot be verified is withheld rather than published. Where a reviewer disagrees with a question's marked answer, the question is flagged and repaired in the bank instead of being papered over.
The study notes go through the same discipline. Each section is expanded against the EASA syllabus, then reviewed for factual accuracy by several independent passes before it reaches a paying reader, with an automated check confirming that nothing from the previous version was lost along the way. Corrections are made in the text itself — a note never tells you that its own earlier statement was wrong.
Written
Against the published EASA syllabus for the module.
Reviewed
By multiple independent passes looking for factual error.
Corrected
In place, in the bank, when a reader or reviewer finds a fault.
