Accident Overview
A commercial aircraft operating out of Batagay Airport encountered technical difficulties with both engines shortly after takeoff, during initial climb. The pilot-in-command, unable to achieve sufficient altitude, attempted an emergency landing near a river located approximately one kilometer from the airfield. The airplane struck trees, crash-landed, lost its undercarriage, and came to rest in a wooded area. All five crew members on board were uninjured, but the aircraft sustained substantial damage and was written off.
Probable Cause
The official investigation determined that the crew failed to prepare the flight properly and hurried the departure. With an outside air temperature of -48°C, the oil was not sufficiently warm, which caused the engine to run improperly after rotation. The propellers became blocked in an angle between 20° and 30°, generating additional drag and impeding the airplane's ability to gain sufficient altitude. In such conditions, an emergency landing was unavoidable.
