was cleared to 2000 feet after reporting between 7000-6000 feet when 14 miles out. The aircraft later crashed into a mountain.
PROBABLE CAUSE: "Collision with rising terrain as the crew descended the aircraft below safe altitude owing to incorrect identification of their position vis-a-vis the airport. The investigation is of the opinion that this was the result of dependence on Doppler and Weather Radar Systems on board PH-MBH which left room for misinterpretation."
