What happened
During an approach with an incorrect configuration, the twin-engine aircraft flew over the runway threshold at an altitude of approximately 20 meters. As the aircraft reached a point 300 meters beyond the runway end, the flight engineer, who was performing copilot duties, decreased power on both engines to a level above idle.
In response, the captain assumed control of the aircraft and applied maximum power to initiate a go-around procedure. During this maneuver, the left engine entered an autofeather state. While traveling at a speed of 170 km/h, the aircraft entered a steep left bank of 70 degrees, which led to an aerodynamic stall. The aircraft subsequently crashed at a distance of 1,526 meters beyond the runway threshold. The accident resulted in two fatalities, including one pilot, and seven injuries.
Findings
- The aircraft was operating with an incorrect approach configuration prior to the incident.
- The left engine's transition to autofeather during the application of maximum power triggered the loss of control.
