What happened
Shortly after departing from Kuybyshev Airport, an aircraft entered a stall while attempting to climb to an altitude of approximately 40 to 50 meters. During this phase of flight, the plane banked to the left and impacted a snow-covered field situated roughly 2,300 meters beyond the runway threshold.
The accident resulted in the deaths of all nine crew members and 16 passengers, totaling 25 fatalities. Additionally, 14 others sustained serious injuries. Following the impact, five of the survivors succumbed to their wounds several hours later.
At the time of the incident, the flight was being conducted as a training mission, with an instructor occupying the right seat and the pilot-in-command operating the controls.
Findings
While investigators could not establish a definitive cause for the crash, evidence suggested a loss of control related to instrument failure. It is believed that the attitude indicator was malfunctioning, possibly due to water entering the device. This malfunction occurred very early in the flight, less than two minutes after the engines had been started.
