The Boeing 737 departed Adana at 00:36 for a flight to Jeddah to pick up Turkish pilgrims. Weather was poor when the plane crashed, nine minutes after takeoff. The wreckage was found to have been scattered over a 500sq feet area. Also, a 10 m deep hole was found at the point of impact.

Probable Cause:

- The severe weather conditions probably contributed to the cause of the accident.
- The pitot static anti-ice system was probably not activated during preparations for flight because of missed checklist items.
- The crew failed to recognize the cause of an erratic airspeed indication.
- The crew failed to use other cockpit indications for control and recovery of the airplane.
- The presence of cabin crew in the cockpit probably distracted the attention of the cockpit crew.
