Approach
The crew initiated the approach to Ankara-Esenboğa Airport under night conditions. Air traffic control cleared the aircraft to descend from 9,000 feet to 8,000 feet for runway 03.
Accident
While operating in low visibility, the aircraft struck a snow-covered mountain located 12 km from the runway threshold. The impact destroyed the aircraft, and all three crew members on board were killed.
Probable Cause
The official investigation determined the probable cause: the aircraft descended below the prescribed altitude limits as a consequence of deviating from instrument flight rules.
