PROBABLE CAUSE: "The commission could not definitely establish the cause of the IL-18 (LZ-BEN) aircraft.
The Commission assumed that the most probable cause of the accident was insufficient evaluation of terrain relief and weather conditions in the Bratislava Airport control zone by the aircraft crew and lack of adaption of the flight to these conditions."
