While cruising at an altitude of 990 metres approximately 50 kilometres from Ashgabat, the aircraft encountered poor weather conditions. The airplane subsequently struck the slope of Mount Uldepe, which has an elevation of 1,631 metres. The impact caused the aircraft to disintegrate, resulting in the death of all six crew members.
