What happened
During a local training session at Tyumen-Roshchino Airport, the crew performed four consecutive touch-and-go maneuvers. These maneuvers were executed at a notably elevated speed. During the final approach, the aircraft was configured with flaps set between 15° and 20°.
Upon making contact with the runway at high velocity, the rear right tire of the left main landing gear disintegrated. The resulting debris from the burst tire severed a hydraulic line, which led to the partial retraction of the landing gear assembly. This mechanical failure triggered a fire within the wheel well area as the aircraft continued along the runway.
Despite the intensity of the fire and the structural damage to the airframe, all occupants managed to evacuate the aircraft without injury. The total number of fatalities was zero, though the aircraft sustained damage that rendered it a total loss.
Findings
Investigation into the incident determined that the sequence of high-speed landings placed excessive stress on the landing gear components. The primary factor in the accident was that the tire burst upon touchdown, which subsequently caused the hydraulic puncture and the collapse of the left main gear.
