CASA Part 66 (Australia)
CASA Part 66 exam preparation
Australia's CASA licenses aircraft maintenance engineers under CASR Part 66, and its basic knowledge modules mirror the EASA Part-66 module structure. That means the same practice bank — the maths, physics, electrical, aerodynamics and engine modules — is strong preparation for the CASA module exams.

A module structure that mirrors EASA
CASA Part 66 adopted the internationally recognised module framework, so the technical subjects line up closely with EASA Part-66. Working through the module banks here builds exactly the knowledge the CASA basic exams assess.
Self-study and exam readiness
Many CASA candidates prepare by self-study before sitting the basic knowledge exams. Practising thousands of questions with an explanation on every answer — and tracking your score against the 75% mark — is a proven way to get exam-ready and find your weak spots.
Watch the legislation module
Module 10 (Aviation Legislation) is the one area that is genuinely national — it covers the Australian regulatory framework rather than the EASA one. Treat that module here as background on structure and concepts, and study the current CASA references for the specifics.
Frequently asked questions
Do EASA Part-66 questions help for CASA Part 66?
Yes, for the technical modules. CASA's module framework mirrors EASA Part-66, so the maths, physics, electrical, aerodynamics, structures and engine modules are the same core knowledge.
What is the CASA pass mark?
The Part 66 basic knowledge module exams use a 75% pass mark, the same threshold this site scores you against.
Which module should I not rely on for Australia?
Module 10 (Aviation Legislation) — it is jurisdiction-specific. Use it for the general concepts, then study the current CASA regulatory material for the exam.
