Probable cause

The pilot’s failure to maintain clearance from a power transmission line tower while maneuvering to pick up a rope in gusting wind conditions.

NTSB narrative

The pilot reported that he was maneuvering the helicopter into position near a 150-foot-tall power transmission line tower to prepare to attach a line to a rope and pull it through a traveler for power line construction. The wind had increased and was gusting, and the main rotor blades struck the tower. The helicopter spun around, and the tail rotor subsequently struck the tower. The tail rotor and tail rotor gearbox separated from the helicopter as it descended to the ground. A postcrash fire consumed the wreckage. The pilot did not report any mechanical malfunctions or failures with the helicopter that would have precluded normal operation. It is likely that the gusting wind conditions negatively affected the pilot's ability to maintain sufficient clearance from the tower while maneuvering into position.
