The powerline had an oscillation as lineman was disconnecting from it, at the same time the tailwind moved the tail rotor closer to the line. A tailrotor strike occurred. The damage was discovered upon shutdown. The tail rotor blades were replaced. This was last of four splices made on a 90 degree plus day. The lineman and pilot were fatigued.
