An aircraft crashed 8.5 km southeast of Sverdlovsk-Koltsovo Airport during its initial climb, resulting in three fatalities and three injuries.

What happened

Shortly after departing from Sverdlovsk-Koltsovo Airport, the aircraft entered a period of severe icing while in the climbing phase. During this ascent, ice accumulated on the windshield, significantly obstructing the pilot's visibility. This led to a loss of control, causing the plane to bank to the right and impact a field near the Iset River, approximately 8.5 km southeast of the airfield. The impact occurred with the right wing hitting the ground first.

There were five people on board during the flight. The accident resulted in three fatalities and three injuries.

Probable cause

The accident was caused by improper flight techniques and inadequate crew training during severe icing conditions.
