Accident Details
The approach to Lviv Airport was conducted under night and icing conditions with limited visibility. While on final approach, at an altitude of 110 meters, the flaps were lowered to 45°. The aircraft then nosed down and crashed in a field located 2,100 meters short of the runway threshold. The impact resulted in a huge explosion, and the aircraft disintegrated on impact. All 40 occupants were killed.
Probable Cause
The official investigation determined the probable cause to be a loss of control in icing conditions when the flaps were extended to 45° on approach, apparently due to an excessive accumulation of ice on the wings and stabilizers. Additionally, the distance between the aircraft and the ground was insufficient to permit a recovery.
