Circumstances:
The commercial certificated pilot was attempting to land on a remote runway during a Title 14, CFR Part 135, cargo flight. The approach
end of the runway is located at the edge of a river. During the pilot's fourth attempt to land, the airplane collided with the river
embankment, and sustained structural damage. The director of operations for the operator reported that he interviewed several witnesses
to the accident. They told him that the weather conditions in the area had been good VFR, but as the pilot was attempting to land, rain
and mist moved over the area, reducing the visibility to about 1/4 mile. Within 30 minutes of the accident, the weather conditions were
once again VFR. The pilot told an FAA inspector that the weather conditions consisted of a 500 foot ceiling and 2 miles of visibility.
The pilot reported that he made 3 passes over the runway before attempting to land. On the last landing approach, while maintaining 80
knots airspeed, the pilot said the nose of the airplane dropped, he applied full power and tried to raise the nose, but the airplane
collided with the river bank.
Probable cause:
The pilot's misjudgment of distance/altitude during the landing approach, which resulted in an undershoot and in-flight collision with a
river embankment. Factors contributing to the accident were reduced visibility due to rain and mist.
