Incident Overview
A helicopter engaged in fire suppression activities for the U.S. Forest Service sustained substantial damage after striking powerlines. The pilot reported that the water bucket malfunctioned on the seventh load, preventing water release. While returning to the helibase, the pilot diverted from the direct route.
Maneuvers to Empty the Bucket
The pilot descended and circled with the intention of setting the bucket down on an abandoned railroad grade to tip it over and empty it. An eyewitness observed the pilot descending and circling, believing he was attempting to fill the bucket from a pond located just across the railroad grade.
Powerline Strikes
Approximately 80 feet above the pond, the helicopter's main rotor blades struck a powerline, severing three conductors of a main distribution line. About 80 feet further west along the same powerline, the main rotor blades cut the messenger wire in two places, approximately 12 feet apart.
Landing and Aftermath
Despite the damage, the helicopter remained controllable. The pilot continued a right turn, descended, and landed on the railroad grade. The helicopter sustained substantial damage, but no further details on injuries or fatalities were provided in the source.
Eyewitness Account
An eyewitness provided a differing perspective, stating that the pilot appeared to be descending and circling to fill the bucket from the pond, rather than emptying it on the railroad grade.
