After takeoff from Juara Airport, while climbing, the crew declared an emergency after the failure of the left engine. The crew was cleared to return and the rescue teams were dispatched at the airport. On final approach, during the last segment, the aircraft went out of control and struck the ground. It veered off runway and collided with an emergency vehicle (fire bombers truck) before coming to rest in flames. All 17 occupants were killed while no one on the ground was injured.
Probable cause (official findings): A left engine faulty fuel injection nozzle caused a blow torch effect, damaging compressor turbine vane ring and causing thermal fatigue and loss of one of the turbine blades. The resulting imbalance ruptured the starting control bypass fuel return.
