The helicopter was destroyed after it collided with trees and terrain at night. Visual meteorological conditions were reported en route, however, persons in the area near the crash site reported isolated severe thunderstorms in the vicinity. One person living about 10 miles from the site noticed a ragged low ceiling, with approximately 200 to 500 feet visibility at the time it was becoming dark. He said that he didn't pay attention to the weather after dark, except to note that there were rain showers. He mentioned that he had flown the anticipated route many times, and that the ridge where the helicopter impacted is the first high terrain coming east along that route.
Probable Cause: The pilot's failure to maintain clearance from terrain. Factors include low clouds and visibility and near-night light conditions.
