Incident Details
A training flight departed from Ulan-Ude-Mukhino Airport for local maneuvers. After completing several circuits, the crew decided to simulate an engine failure by shutting down one engine. Once the propeller was feathered, the flight engineer inadvertently shut down the second engine, resulting in a loss of thrust.
Landing and Aftermath
The crew executed a belly landing on Bodorodski Island, approximately 8 kilometers short of runway 26. The aircraft was partially consumed by a post-crash fire. All crew members sustained minor injuries.
Probable Cause
The official finding identified the probable cause as the engine being mistakenly shut down by the flight engineer during a single-engine exercise.
