Accident Sequence
The aircraft departed Anadyr Airport at 0919 local time bound for Egvekinot. Five minutes later, the crew encountered poor weather and returned to Anadyr for a safe landing. A second departure occurred at 1213 local time in improved conditions.
While approaching Egvekinot, the pilot encountered low visibility due to low clouds and was unable to distinguish the mountainous terrain. Descending to a height of 235 meters, the aircraft deviated from the prescribed approach path and struck the slope of Mount Dumka. The aircraft passed over the top and crashed in flames on the opposite slope.
Search and Rescue
Search and rescue operations were conducted, and the wreckage was located one day later.
Injuries
Five passengers sustained serious injuries. Twenty-two other occupants were killed.
Probable Cause
Official findings state that the captain decided to continue the approach below the minimum safe altitude of 300 meters despite low visibility due to poor weather and lack of visual contact with the ground. The main approach radio beacon was out of order, while the reserve beacon was running improperly, which was considered a contributory factor.
