Flight Details
The crew was completing a special flight from Keperveem to Deputatsky, with intermediate stops in Chersky and Chokurdakh. After takeoff from Chokurdakh, the crew encountered poor weather conditions and lost orientation. The aircraft deviated from the prescribed route by 110 km.
Emergency Landing
As the airplane ran out of fuel, the crew attempted an emergency landing. The aircraft crash-landed approximately 13 km from Deputatsky. All three crew members escaped uninjured, but the aircraft was damaged beyond repair.
Official Findings
The probable cause, as determined by the investigation, was that the crew failed to properly calculate the wind component en route from Chokurdakh to Deputatsky, causing the aircraft to be off course. Due to a longer flight than initially planned—by two hours and 22 minutes—fuel reserves were low, and the crew was forced to attempt an emergency landing.
