Crew on board:
Pax on board:
While descending to Ölgii Airport, the crew encountered poor weather conditions when the aircraft struck the slope of Mt Marz located in the Hangayn Nuruu Mountain Range. The aircraft disintegrated on impact and all 32 occupants were killed.
Controlled flight into terrain after the crew initiated the descent prematurely, causing the aircraft to descend below the minimum prescribed altitude. Poor visibility due to poor weather conditions was a contributing factor.
