Night Approach Incident at Bereznik: Left Engine Power Loss and Subsequent Crash (CCCP-41831)

Incident Overview and Sequence of Events On a night approach to Bereznik, the aircraft experienced a loss of power in its left engine. The flight crew initiated a go-around maneuver in response to the engine failure. However, the aircraft subsequently banked to the left and began to descend. It struck the tops of trees at a speed of 160 km/h before ultimately crashing into a wooded area. The impact resulted in injuries to all four crew members and four of the sixteen passengers on board. The remaining occupants escaped the incident without injury. ## Official Findings and Probable Cause The official investigation determined that the incident was caused by a mechanical failure involving the engine control system. Specifically, the cable connected to the left engine throttle lever disconnected during the approach phase. This disconnection caused the engine's revolutions per minute (rpm) to drop, resulting in the loss of power that precipitated the subsequent go-around and crash.
