Circumstances:
The single engine airplane departed Ust-Kara on a schedule service to Naryan-Mar with an intermediate stop in Karatayka, carrying 10 passengers and two crews. Approaching Karatayka, the crew encountered icing conditions and decided to divert to Varandey. Engine power was at maximum but the airplane was unable to climb above 200 metres. In such conditions, the captain decided to attempt an emergency landing when the airplane crashed landed in a snow covered area located some 10 km northwest of Karatayka. A passenger and the captain were killed while 10 other occupants were injured. Shortly before the accident, the crew reported severe icing conditions.
Probable cause:
An emergency landing was necessary because of the inability to continue the flight due to the impact of icing on the aircraft's aerodynamic and thrust characteristics.
The following contributing factors were identified:
- The captain's failure to consider potential risks of the aircraft encountering icing conditions when making the decision to take off;
- The captain's delayed decision to change the flight plan despite receiving information about deteriorating meteorological conditions at the destination, which fell below the established thresholds for VFR (Visual Flight Rules) night flights and indicated the possibility of aircraft icing;
- Non-compliance with VFR rules regarding prolonged flight in actual icing conditions.
