Accident Details
Shortly after takeoff from Novaya Derevnya, while climbing to an altitude of approximately 10 meters, the aircraft experienced an uncommanded roll to the left, reaching a bank angle of 35 degrees. Subsequently, the aircraft lost altitude and impacted trees located 145 meters from the departure point. The collision resulted in injuries to both pilots and substantial damage to the aircraft, rendering it beyond repair.
Probable Cause
According to the official investigation, the probable cause of the accident was a stall during the initial climb phase. The stall occurred because snow and ice/frost remained on the wings, tail, and fuselage. Additionally, the investigation identified several contributing factors: the crew failed to conduct a pre-takeoff inspection of the aircraft, failed to prepare the flight in accordance with published procedures, and failed to arrange for appropriate deicing or cleaning before takeoff.
