The operator reported that the pilot was positioning a concrete bucket as an external load attached to a long line. At the end of the long line was a remote hook that was activated electrically from the cockpit. The pilot maneuvered the concrete bucket to the work location, which placed the long line 15-20 feet from a known energized power line. The energized electrical power line arced to the long line, and electrical energy was conducted down the remote hook circuit to the bucket, seriously injuring a construction worker who was ground handling the bucket.
Probable Cause: Arcing of an energized electrical power line to the external long line and the conduct of electrical energy to ground personnel.
