The aircraft left Biskra at 0643LT on a routine transport flight to Oujda. Five minutes before its own signaled ETA, the pilot took advantage of a hole in the cloud over which he had been flying for some considerable time, to get below the cloud. Upon breaking cloud, the aircraft was seen to circle in a valley. Unaccountably, the aircraft was seen to turn to port and climb into cloud away from a road and valley, which was clear, with visibility 4 to 5 miles below cloud. The mountaintop was covered by drifting cloud at the time and the aircraft was climbing steeply when it crashed. It crashed into the side of a mountain, killing 16 on board. One passenger survived.
