Accident
Shortly after takeoff from Zyrianka Airport, while climbing to a height of about 20 meters, the left engine encountered problems. The crew attempted to feather the propeller, but without success. In these conditions, the pilot-in-command decided to attempt an emergency landing. At a speed of 140 km/h, the airplane struck trees and crashed in a wooded area located 600 meters past the runway end. The aircraft was damaged beyond repair. All 16 occupants were rescued.
Investigation
The official investigation determined the probable cause of the accident. After liftoff, when the undercarriage were raised, the left engine suffered technical issues. The crew was forced to feather the propeller, but the procedure was unsuccessful. The propeller then windmilled, creating drag. Consequently, the aircraft lost height, and the pilot elected to make an emergency landing.
A contributory factor identified by investigators was that the board mechanic was unable to respond immediately to the engine issue. The mechanic was focused on an instruments check, particularly the speed indicator, which delayed his reaction.
Conclusion
The aircraft was destroyed, but no fatalities were reported. The investigation highlighted mechanical failure and crew response issues.
