Analysis
The plt was delivering supplies from a mountain site to a river work site. He stated that on his 10th & last flt, the wind caused the helicopter & external load combination to shift laterally. At that time, the load/line became entangled in a tree. The helicopter began moving in an arc & subsequently crashed in the river. The plt stated that he was unable to release the load; altho, he had previously checked the electrical & manual release mechanisms & they operated normally. He estimated that the wind was from 050 deg at 5 gusting 7 KTS. The elevation of the crash site was about 3100 ft.
