The pilot was conducting logging operations in steeply sloped, tree covered mountainous terrain utilizing a 200 foot long line. Witnesses observed the rotorcraft in a hover at treetop level attempting to pick up a log when the right rotor blades began contacting treetops. The rotorcraft rolled and then descended to ground impact.
Probable Cause: The pilot's failure to maintain adequate clearance with trees during logging operations. Contributing factors were the trees, mountainous (steeply sloped) terrain, and the pilot's decision to conduct operations in this terrain with a 200 foot long line.
