Fatal Crash During Approach to Vitebsk in Icing Conditions

Vitebsk, BelarusLanding (descent or approach)

On January 7, 1974, an Antonov AN-12 operated by Soviet Air Force - Voyenno-vozdushnye sily CCCP was involved in an aviation accident near Vitebsk, Belarus during landing or approach. 26 people were killed. Investigators recorded the probable cause as: Excessive accumulation of ice on wings, stabs, and fuselage during an approach in severe icing conditions, compounded by the apparent failure of the crew to switch on deicing systems. This summary draws on records from the Bureau of Aircraft Accidents Archives (B3A); 8 related events involving the same aircraft type or operator are linked below.

An aircraft crashed into a field near Vitebsk after losing control during an approach in severe icing conditions. The accident resulted in 26 fatalities and five survivors among the occupants, who were military personnel en route from Pskov.

Incident Overview

A fatal aviation accident occurred while an aircraft was on final approach to Vitebsk. The flight originated in Pskov and was transporting military officers participating in a training exercise. During the descent, the crew encountered severe icing conditions that led to a loss of control over the airplane.

Accident Sequence

As the aircraft attempted to complete its approach, it lost altitude rapidly. The uncontrolled descent caused the plane to strike power cables before ultimately crashing into an open field. Upon impact, the aircraft caught fire. Emergency response efforts resulted in five passengers surviving the incident, while 26 other occupants were killed.

Investigation Findings

Official investigation findings indicate that the primary factor contributing to the accident was the excessive accumulation of ice on critical flight surfaces, including the wings, stabilizers, and fuselage. This buildup occurred during the approach phase under severe icing conditions. The report notes that various deicing systems available on the aircraft were apparently not activated by the crew, which likely exacerbated the loss of aerodynamic performance and control.
