UK CAA Part-66
UK CAA Part-66 exam preparation
After Brexit the UK kept the Part-66 system almost unchanged: the UK CAA licenses aircraft maintenance engineers under UK Regulation (EU) No 1321/2014, retained in UK law. The modules, categories and exam format are the same ones EASA uses — so the same practice bank works for UK candidates.

The same modules and syllabus
UK CAA Part-66 uses the same numbered modules as EASA — Mathematics, Physics, Electrical and Electronic Fundamentals, Human Factors, and the rest — with the same knowledge levels per category. Practising the module question banks here maps directly onto what you sit for a UK Part-66 licence.
The same 75% pass mark
UK CAA basic knowledge exams keep the 75% pass mark and the multiple-choice format for the module exams, with the familiar penalty for wrong answers on some papers. Our practice tests report your percentage against that 75% threshold so you know when you are ready.
Where UK and EASA now differ
Since 2021 UK and EASA licences are issued separately and are no longer automatically recognised in each other's systems — conversion routes exist if you hold one and need the other. The knowledge exam syllabus, however, is still the shared Part-66 material, which is exactly what this bank covers.
Frequently asked questions
Can I use EASA Part-66 questions for the UK CAA exams?
Yes. The UK retained the Part-66 module structure and syllabus, so the technical modules (1–9, 11–17) are the same material. Practising the EASA-based bank is valid preparation for the UK CAA module exams.
Is the pass mark the same?
Yes — the UK CAA keeps the 75% pass mark for the Part-66 module knowledge exams, the same as EASA.
What about Module 10 (Aviation Legislation)?
Legislation is the one module where UK and EASA content diverges most, because it covers the regulatory framework itself. Use Module 10 here for the general structure and concepts, but always cross-check the current UK CAA regulatory references before your exam.
