Total Training Support's Integrated Training System. We are sure you will need no other reference material to pass your EASA Part-66 exam in this Module.
These notes have been written by instructors of EASA Part-66 courses, specifically for practitioners of varying experience within the aircraft maintenance industry, and especially those who are self-studying to pass the EASA Part-66 exams.
They are specifically designed to meet the EASA Part-66 syllabus and to answer the questions being asked by the UK CAA in their examinations.
The EASA Part-66 syllabus for each sub-section is printed at the beginning of each of the chapters in these course notes and is used as the “Learning Objectives”.
We suggest that you take each chapter in-turn, read the text of the chapter a couple of times, if only to familiarise yourself with the location of the information contained within. Then, using your club66pro.co.uk membership, attempt the questions within the respective sub-section, and continually refer back to these notes to read-up on the underpinning knowledge required to answer the respective question, and any similar question that you may encounter on your real Part-66 examination. Studying this way, with the help of the question practice and their explanations, you will be able to master the subject piece-by-piece, and become proficient in the subject matter, as well as proficient in answering the CAA style EASA part-66 multiple choice questions.
The course notes are written to suit Licence category 'B1' and 'B2', but are also suitable for Licence category 'A'.
