ExploreAbout this exam
The GCAA CAR-66 B1 Aircraft Maintenance Licence Examination is the knowledge-testing step for candidates seeking a B1 (mechanical) aircraft maintenance licence under the UAE General Civil Aviation Authority's CAR-66 regime. It is aimed at technicians and engineers who perform and certify maintenance on aeroplanes or helicopters and who need to demonstrate the theoretical knowledge required before licence issue. The examination spans the standard CAR-66 B1 module set: aviation legislation, human factors, air law and the regulatory framework, aircraft general knowledge and maintenance practices, electrical and electronic fundamentals, materials and hardware, maintenance practices, aerodynamics, structures and systems, gas turbine engines, and propellers. Preparation should combine structured self-study of the applicable modules with hands-on familiarity with the aircraft types and tasks you actually work on. Use the GCAA website as the authoritative reference for current regulatory requirements, and confirm examination arrangements, module applicability and any administrative conditions directly with the Authority or your approved training organisation, since published details can change.

What you'll study
About GCAA CAR-66 B1 Exam preparation
What is the format of the CAR-66 B1 exam?
The examination is delivered in multiple-choice format, module by module, matching the CAR-66 B1 syllabus. Confirm the current delivery method, module list and any per-module question counts directly with the GCAA or your training organisation before you book, as administrative arrangements are set by the Authority rather than by study providers.
How long is the exam and what is the pass mark?
Neither the duration nor the passing score is published in the source material used for this page, so no figure is quoted here. Passing standards and time allowances are set by the GCAA and can be revised. Check the current CAR-66 requirements and your examination notification for the exact values that apply to your sitting.
How many questions are on the exam?
The total question count is not stated in the available source material, so it is not given here. Question numbers typically vary by module in licence examinations, and the Authority controls the current specification. Refer to official GCAA documentation or your approved training organisation for the definitive structure before planning your revision.
Can I retake a failed module?
Retake rules are not specified in the source material available for this page, so no policy is quoted. In practice, licence examinations are usually modular, meaning you can resit individual failed modules rather than the whole examination. Confirm the current retake conditions, any waiting periods and any limits with the GCAA.
How much does the exam cost?
The fee is not published in the source material used here, so no amount is quoted. Fees are set by the GCAA and may differ by module, location and whether you sit through an approved training organisation. Check the GCAA services pages or contact the Authority directly for the current charge before booking.
How long is the licence valid?
The validity period is not stated in the source material available here, so no figure is given. Licence validity and the associated recency and continuation requirements are defined in the CAR-66 regulation and can change. Always verify the current rules on the GCAA website rather than relying on second-hand information.
In what order should I study the modules?
Start with Aviation Legislation and Air Law so the regulatory context frames everything else, then build technical depth through Electrical and Electronic Fundamentals, Materials and Hardware, and Maintenance Practices. Aerodynamics, Structures and Systems, Gas Turbine Engines and Propellers come last, because they draw on the earlier material. Human Factors is short and fits anywhere.
What causes most failures?
Common causes are treating the exam as pure memorisation, skipping the legislation and human factors modules as 'easy', and underestimating maintenance practices where documentation, inspection and safety procedures are tested in detail. Weak numeracy in electrical fundamentals also costs marks. Study to the syllabus, practise calculations, and revise the regulatory modules as seriously as the technical ones.
Where do I find the official requirements?
The General Civil Aviation Authority website at gcaa.gov.ae is the authoritative source for UAE aviation legislation, regulations and service information. Use it to confirm the current CAR-66 requirements, examination arrangements and any updates. This page is an independent study aid and is not affiliated with the GCAA.
