CAAB AME B1.1 Exam · Put your knowledge to work in context.
The CAAB AME B1.1 Exam is the examination pathway administered by the Civil Aviation Authority of Bangladesh (CAAB), the national aviation regulator, for candidates seeking aircraft maintenance engineering certification in the B1.1 mechanical (aeroplane) category. The regulator publishes the exam through its own website, where the e-Exam section sits alongside licence and approval services, and where a separate notice invites candidates to the paper-based examination circular and form. The CAAB AME B1.1 Exam case studies are 5 cases and about 2,106 words.
1Torque Wrench Out of Calibration Mid-Job
A B1.1 engineer is torquing the cylinder hold-down nuts on a horizontally opposed engine. The specification is 45 N·m ± 5%.
434 words, about 2 min2Corrosion Found Beyond the Inspection Zone
During a scheduled 200-hour inspection on a light twin, a B1.1 engineer removes an inspection panel on the lower wing skin and finds intergranular exfoliation corrosion around 6 adjacent rivets, covering roughly 40 mm × 25 mm. The approved maintenance data defines this area as a non-critical inspection zone and gives a blend-out limit of 10% of skin thickness, with re-inspection at the next 100-hour check.
431 words, about 2 min3Intermittent Electrical Fault After Component Swap
A B1.1 engineer replaces a failed fuel boost pump on a twin-engine aircraft. After the swap, the left boost pump low-pressure warning illuminates intermittently in flight, roughly every 20 minutes, and clears when the aircraft climbs.
416 words, about 2 min4Sign-Off After an Unrecorded Repair
A B1.1 engineer is asked to certify the completion of a scheduled check on an aircraft that has just come from another maintenance organisation. The paperwork shows a repair to a flap track fairing carried out 3 days earlier, but the repair record lacks the approved data reference, the material batch number, and the signature of the person who did the work.
398 words, about 2 min5Engine Trend Shift After a Compressor Wash
A B1.1 engineer supervises a compressor wash on a turbofan engine during a line check. Before the wash, the engine trend monitoring showed exhaust gas temperature (EGT) margin of 18 °C above the red line at takeoff.
