What happened
During a visual approach to runway 24, the flight crew failed to maintain an adequate altitude above the surrounding terrain. Approximately 8 km before reaching the runway, the aircraft collided with the slope of a mountain.
The impact forces were severe enough to result in the total destruction of the airframe. There were four fatalities among the occupants of the plane, with no survivors reported from the crash site.
Findings
Investigations into the accident determined that the crew did not recognize that the aircraft's altitude had become dangerously low during the final stages of the approach. The primary factor in the accident was controlled flight into terrain.
