The official investigation into the crash by the Interstate Aviation Committee revealed that whilst snow was removed from the aircraft exterior, de-icing fluid was not applied. The crew did not ask for permission to enter the taxiway, which was done at too high a speed for the icy conditions, and the flaps were set to 11 degrees, instead of 20 degrees.
The aircraft reached a speed of 165 km/h, when the crew began to rotate the aircraft, at which stage it reached a 13-degree angle of attack, and stalled 8–10 metres off the ground. The airplane rolled left and struck the ground with a 60-65 degree bank angle and crashed.
