What happened
During a mission to return 10 children from holiday destinations in the Andryushkino area of Yakutia, a flight crew attempted to land on a body of water that was insufficient for the aircraft's requirements. The lake used for the landing measured only 380 meters in length, failing to meet the necessary minimum safety distance of 850 meters.
As the single-engine airplane attempted to depart from this first location, the aircraft made contact with the shoreline. This impact resulted in damage to the floats. Despite the structural damage, the crew proceeded with a takeoff attempt. Shortly after, while attempting to land on a second lake, the aircraft crashed.
There were 12 occupants on board during the incident. All individuals managed to exit the wreckage without sustaining serious injuries, though the aircraft was determined to be a total loss due to the extent of the damage.
Findings
Investigations into the accident identified that the primary contributing factors were inadequate flight preparation and errors in judgment by the crew regarding the suitability of the landing site.
