What happened
During a routine local training session at Moscow-Chkalovky Airport, the crew was performing a series of touch-and-go maneuvers. While the aircraft was in its initial climb at an altitude of approximately 70 meters, it experienced a right-hand bank and subsequently lost altitude.
The descent ended when the aircraft struck a lake situated near Kudinovo, which is roughly 15 km southeast of the airfield. The impact resulted in the total destruction of the aircraft. There were six fatalities among the occupants on board.
Findings
Investigations into the accident suggest that the primary factor was an engine failure on the right side of the aircraft during the climb. The specific reason for the failure of the right engine remains undetermined.
