Investigating agency: NTSB
Narrative:
The commercial pilot of the helicopter reported that the purpose of the flight was to lift a utility company lineman to a structure to perform work in conjunction with a new powerline project. While transporting the lineman to the structure using a long line, the worker contacted an existing, live powerline and was seriously injured. The weather conditions at the time of the accident included 10 miles visibility and no precipitation. The pilot reported that he could not see the powerline from his perspective until it was too late to make a course change. The pilot recommended that better recognition of hazards and obstructions may have prevented the accident.

Probable Cause: The pilotís failure to recognize and compensate for hazards during the external load operation, which led to a collision between a lineman (external load) and a powerline.
