Accident Details
A single-engine aircraft operated a spraying mission over a forest area, departing from Yeniseysk in the afternoon with two pilots on board. Approximately 40 minutes into the flight, while completing a third pass at an altitude of about 400 metres, smoke spread inside the cockpit. The crew decided to return to Yeniseysk, but a few minutes later, the engine lost power. Fuel leaked from the engine and spread over the windshield.
The crew reduced the altitude to 50 metres and the speed to 85 km/h in preparation for an emergency landing. With the flaps extended to 45°, the aircraft collided with trees and crashed in a wooded area located 75 kilometres north of Yeniseysk. Both pilots sustained minor injuries, and the aircraft was damaged beyond repair.
Probable Cause
The official investigation determined the probable cause to be a loss of engine power due to the failure of cylinder number 5, caused by faulty manufacturing.
