What happened
During the final approach phase toward Aldan Airport, the flight crew attempted to configure the aircraft for landing by extending the flaps to 42°. During this maneuver, the aircraft's nose pitched upward to an angle of 42.5°. In response to this change in attitude, the crew initiated a go-around procedure to recover the flight path.
However, the airspeed decreased significantly during the maneuver, falling to 52 km/h. This loss of momentum led to an aerodynamic stall. The aircraft subsequently impacted the ground 273 metres before reaching the runway threshold, landing 160 metres to the left of the extended centerline. The impact forces were sufficient to destroy the aircraft. There were 24 fatalities among the occupants of the flight.
Findings
- The aircraft entered a stall during the transition to a go-around.
- A significant drop in airspeed occurred following the nose-up pitch during flap extension.
