ExploreAbout this exam
The CAAB AME B1.3 exam is the licence-category knowledge assessment administered by the Bangladesh Civil Aviation Authority (CAAB, বেবিচক) for aircraft maintenance engineers. CAAB's own site lists an e-exam section for AME candidates alongside paper-based exam circulars and forms, so candidates should expect a multiple-choice format delivered electronically or on paper depending on the circular in force. The exam is intended for maintenance personnel seeking B1.3-category recognition and for those who must demonstrate current regulatory knowledge. Its scope is broader than pure technical maintenance: CAAB publishes separate regulator sections for ANO and CAD circulars, legislation (Civil Aviation Act 2017, CAA Act 2017, CAR 84, and the 2023 heliport and elevated heliport rules), aerodrome standards (AGA) with ANO, CPD, guidance material and inspector checklists, and AVSEC with its act, regulations, circulars and voluntary reporting channel. Preparation should therefore mirror those published sections: read the ANO and CAD circulars, the Act and CAR 84, the AGA standards and inspection material, and the AVSEC regulations and voluntary reporting guidance. Watch the notice board, since CAAB posts draft amendments (for example the draft ANO 10 Volumes 1 to 5 amendment opened for stakeholder comments) and new regulations such as the General Civil Aviation Regulations 2026.

What you'll study
About CAAB AME B1.3 Exam preparation
What is the CAAB AME B1.3 exam?
It is the licence-category knowledge examination run by the Bangladesh Civil Aviation Authority for aircraft maintenance engineers. CAAB's website maintains a dedicated e-exam section for AME and separately publishes paper-based exam circulars and forms, so the delivery method depends on the circular applicable to your sitting.
What format should I expect?
CAAB publishes both an e-exam channel for AME and paper-based exam circulars and forms, so the format is announced per sitting rather than fixed permanently. Prepare for multiple-choice questions and confirm the format, schedule and venue from the current CAAB circular and exam schedule before the closing date.
Which regulations are examinable?
CAAB's regulator pages list the Civil Aviation Act 2017, the CAA Act 2017, CAR 84 and the 2023 heliport and elevated heliport rules under legislation, plus Air Navigation Orders, CAD circulars, aerodrome standards (AGA) material, and AVSEC act, regulations and circulars. Treat each published section as a study area.
How long is the exam and what is the pass mark?
CAAB's public page does not state a duration, question count or passing score for the AME B1.3 e-exam. Those details appear in the exam circular and schedule issued for each sitting. Check the notice board and the e-exam section directly rather than relying on second-hand figures.
What does it cost and can I retake it?
The CAAB website does not publish an AME B1.3 exam fee or a retake policy on its public page. Both are set through the exam circular and office orders. Read the current circular carefully, and contact CAAB through the published contact details if the circular is silent.
How should I order my study?
Start with the legal framework (Civil Aviation Act 2017, CAA Act 2017, CAR 84), then the Air Navigation Orders and CAD circulars, then aerodrome standards and AGA inspection material, and finish with AVSEC regulations and voluntary reporting. Finish with licence-category maintenance knowledge, since it underpins every regulatory topic.
Why do candidates fail this exam?
The most common cause is studying only technical maintenance and skipping the regulatory domains, which carry substantial weight. Another is relying on outdated regulation text: CAAB has announced new General Civil Aviation Regulations 2026 and opened a draft amendment of ANO 10 Volumes 1 to 5 for stakeholder comments, so always check the notice board.
Are draft regulations examinable?
CAAB's notice board dated 14-10-2026 invites stakeholder comments on a draft amendment of ANO 10 Volumes 1 to 5, which is not yet in force. Learn the version currently in force, but be aware of announced changes such as the General Civil Aviation Regulations 2026 so you are not surprised by revisions.
Where do I find official exam notices?
Use the CAAB website notice board, the e-exam section, and the paper-based exam circular and form page. CAAB also publishes an exam schedule. These are the authoritative sources for dates, eligibility and instructions; this study page is independent and not affiliated with CAAB.
