What happened
During a routine crop-spraying operation in the Krasny Yar district of the Kuibyshev region, an aircraft experienced a sudden loss of engine power while in flight. In response to the mechanical failure, the crew attempted to execute an emergency forced landing. During this maneuver, the aircraft struck several trees, which led to the total destruction of the plane.
While the impact was severe enough to destroy the airframe, both members of the flight crew managed to escape the wreckage. The incident resulted in two injuries among the crew, though no fatalities were reported from the crash site.
Findings
Investigations into the mechanical failure determined that the engine ceased to function properly because of a specific component malfunction. Specifically, the loss of power was triggered by problems involving a valve coupled with cylinder n°7.
