A Bhutan Airlines Airbus A319-100, registration A5-BAB performing flight B3-700 from Kolkata (India) to Bangkok (Thailand) with about 80 people on board, was preparing for departure from Kolkata when smoke emanated from the APU prompting the flight crew to initiate an evacuation via slides onto the apron. About 20 people received injuries during the evacuation.

A replacement A319-100 registration A5-BAC was flown from Paro (Bhutan) to Kolkata and resumed the flight reaching Bangkok with a delay of 5.5 hours.

The airport reported the aircraft had just been moving to taxi towards the runway for a few seconds when emergency services noticed the aircraft's APU was emitting smoke - at the same time the aircraft's doors were opened and the slides inflated. An immediate response was triggered, the APU was quickly secured. Emergency services needed to treat a number of people with cuts and bruises received as result of the evacuation.

On Sep 10th 2017 it emerged that a subsequent inspection of the occurrence aircraft did not reveal any evidence of fire or heat. Maintenance discovered leaking oil may have dropped onto the hot section of the APU causing the smoke, that had been observed and reported by the crew of another aircraft.

The occurrence aircraft positioned to Bangkok under minimum equipment list requirements with the APU inoperative about 6.5 hours after the occurrence but has not yet resumed service about 27 hours after the occurrence.
