Emergency Declaration
After departing from Juara Airport, the crew of an aircraft declared an emergency during the climb due to a failure of the left engine. Air traffic control cleared the crew to return to the airport, and rescue teams were dispatched to stand by.
Loss of Control
On final approach, during the last segment of the landing, the aircraft went out of control and struck the ground. It then veered off the runway and collided with an emergency vehicle, identified as a fire bombers truck, before coming to rest in flames.
Fatalities
All 17 occupants aboard the aircraft were killed. No injuries were reported on the ground.
Probable Cause
Investigation determined the probable cause to be a faulty fuel injection nozzle in the left engine, which created a blow torch effect. This effect damaged the compressor turbine vane ring, leading to thermal fatigue and the loss of one turbine blade. The resulting imbalance ruptured the starting control bypass fuel return line.
