The helicopter pilot reported that, during an approach to an off-airport construction project landing zone, the helicopter struck a static wire that had been recently positioned above the landing area. The helicopter's main rotor blades contacted the wire which resulted in substantial damage to the blades. The pilot was unaware of the static wire and did not observe it during the approach. The pilot reported that there were no preaccident mechanical malfunction or failures of the helicopter that would have precluded normal operation.

Probable Cause: The pilot's failure to maintain clearance from a static wire during approach.
