Descripción:
The Beech 99 was on short finals when it suddenly pitched up. It entered a steep dive to the left and crashed 150 m short of the runway 19 threshold and left of the extended centreline. The centre of gravity was too far aft (45,0 % MAC whereas the aft limit was 38.4%) due to weight disparity between passengers.
The first officer, who was Pilot Flying on the accident flight, had limited experience on the Beech 99 (28 hours).

Probable Cause:

Probable cause:
The accident was probably caused by the fact that the pilot could not compensate for the rapid pitch-up that occurred when the wing flaps were selected out while the engines were running at high power.
Contributing factors have been:
* The aircraft was extremely tail-heavy.
* The crew's training and overall experience on the aircraft type was limited.
