Weather conditions deteriorated enroute with clouds, turbulences and high winds blowing from the north up to 90 km/h. While overflying the Sikhote-Alin Mountain Range, the aircraft encountered downdrafts and lost altitude. The crew increased engine power and elected to gain height but the aircraft continued to descent until it struck the slope of Mt Tordoki-Yani (1,750 meters high).
