Analysis

The chief pilot reported that, while the pilot was working on transmission power wires, the pilot maneuvered the helicopter closer to the wires to give a better position for the other crewmember.

The pilot moved away from the wires, noticed no abnormality of flight, and returned to the landing zone without further incident. Postaccident examination revealed that the helicopter sustained substantial damage to the tail rotor. The chief pilot reported that there were no preaccident mechanical failures or malfunctions with the helicopter that would have precluded normal operation.
