Accident Summary
On a local training flight from Buguruslan Airport, a single-engine airplane carrying one pilot, one instructor, and two cadets experienced a loss of control in marginal weather conditions characterized by snowfall. The flight had departed at 1332 local time. After completing several circuits at an altitude of 700 meters, the crew informed air traffic control of their intention to descend to 300 meters. Shortly thereafter, control was lost and the aircraft descended, crashing in an open field in the area of Ponikla. The impact ignited a fire that destroyed the airplane. All four occupants sustained fatal injuries.
Investigation Findings
The official investigation into the accident concluded that the exact cause could not be determined with certainty. However, it was reported that the engine failed en route after becoming cold while operating in very low outside air temperature (OAT). The lack of crew experience and skills in winter conditions was considered a contributing factor.
Aircraft and Crew Details
The aircraft was a single-engine airplane used for training purposes. The crew comprised one pilot, one instructor, and two cadets. No further details about the aircraft type or registration were provided in the source.
Circumstances
Weather conditions at the time were marginal due to ongoing snowfall. The flight had executed several circuits at 700 meters before receiving clearance to descend. The loss of control occurred during the descent sequence, leading to the crash in an open field. The post-crash fire resulted in the complete destruction of the aircraft.
