Out of control, the airplane crashed in flames in a wooded area located on the slope of a mountain, some 25 km southwest of the airport. Due to poor weather conditions and the fact that the aircraft crashed in an inaccessible area, the crash site was reached nine days later only. The wreckage was found about 150 feet below the summit and all 79 occupants have been killed. At the time of the accident, ceiling was broken at 2,000 feet and the horizontal visibility was estimated to 1,500 meters.
