Accident
On the day of the accident, the crew was conducting a spraying mission over cotton fields on behalf of the Leningrad State Farm (kolkhoz). While flying at a low altitude, the engine lost power, causing the aircraft to lose speed and height. The crew initiated an emergency landing, but the airplane struck the ground and crashed into a drainage ditch. Both occupants sustained injuries, and the aircraft was destroyed.
Investigation
The investigation into the accident revealed that maintenance on the engine had been scheduled for the day prior to the incident. Specifically, the No. 1 cylinder valve and spark plugs were due for replacement. However, for reasons that could not be determined, this maintenance was not performed according to established procedures.
