What happened
During a routine agricultural spraying operation near the village of Staroye Zhookovo, an aircraft carrying a single occupant crashed. While performing the mission at a low altitude, the pilot experienced a sudden change in the aircraft's flight path as it transitioned into a nose-up attitude. This maneuver led to a rapid loss of altitude, causing the plane to impact a forested region. The impact was followed by a post-crash fire that consumed the wreckage.
There was one fatality involving the pilot, who was the sole person on board at the time of the accident.
Findings
Investigations into the crash focused on the mechanical state of the aircraft's flight controls. It was concluded that a failure within the elevator trim control system occurred during the flight. Specifically, the trim tab became stuck in the full up position, which induced the uncontrolled pitch-up motion and subsequent descent. Because the wreckage was completely destroyed by the post-impact fire, investigators were unable to pinpoint the precise mechanical origin of the component failure.
