Air KBZ AT72 at Yangon on Jan 28th 2014, smoking brakes

An Air KBZ (Air Kanbawza) Avions de Transport Regional ATR-72-500, registration XY-AIW performing flight K7-266 from Yangon to Heho (Myanmar) with 65 people on board, was lined up waiting for departure when the crew decided to return to the apron due to a system malfunction. While taxiing towards the apron smoke began to rise from the left hand main wheels but was noticed only after the aircraft had stopped at the stand and a large smoke plume obscured vision on the apron. Emergency services responded and foamed the main gear. The left main gear tyres deflated due to overheat.

The airline reported the aircraft was on the runway ready for takeoff when a system malfunction prompted the crew to return to the gate. After arrival at the gate one of the tyres was found emitting smoke due to excessive temperature. Airport staff managed the smoke, all 65 occupants left the aircraft without injuries. A replacement aircraft reached Heho with a delay of 2.5 hours.
