On November 22, 1948, a Lisunov LI-2 (registration CCCP-L4463) operated by Aeroflot - Russian International Airlines was involved in an aviation accident near Srednekolymsk, Russia during landing or approach. 23 people were killed. Investigators recorded the probable cause as: The pilot lost control of the aircraft due to a stall caused by excessive reduction in airspeed during the final turn of the approach. This summary draws on records from the Bureau of Aircraft Accidents Archives (B3A); 3 related events involving the same aircraft type or operator are linked below.

An aircraft crashed into the Kolyma River while attempting a fourth approach to Srednekolymsk after losing radio contact and visibility. The accident resulted in 23 fatalities and three serious injuries among the occupants.

What happened

The incident occurred during an approach to Srednekolymsk when deteriorating weather conditions led to a loss of radio communication with air traffic control. Unable to visually identify the airport, the pilot abandoned the initial approach and executed a go-around. Subsequent second and third attempts to land were also aborted due to the same operational difficulties.

During the fourth approach, while completing a turn, the pilot lost control of the aircraft. The plane stalled and impacted the surface of the Kolyma River, coming to rest approximately 400 meters short of the runway threshold. The crash resulted in significant loss of life, with 23 occupants killed and three passengers sustaining serious injuries.

Findings

Analysis of the event indicates that the aircraft was traveling at an insufficient speed during the final turn of the fourth approach. This low airspeed likely contributed to the stall and subsequent loss of control before impact.

Probable cause

The pilot lost control of the aircraft due to a stall caused by excessive reduction in airspeed during the final turn of the approach.
