| Confidence Rating: |  Accident investigation report completed and information captured |
A pilot reported that he was flying his airplane about 0.5 mile behind and slightly above the accident helicopter. He had established radio contact with the two pilots during their takeoff and then made multiple unanswered radio calls to the pilots to warn them about approaching power lines. The main rotor blade struck the power lines and the helicopter subsequently descended into the terrain below and was consumed by a postcrash fire. On scene examination of the wreckage revealed evidence of engine rotation; no anomalies were noted that would have precluded normal operation.
Probable Cause: The pilot’s failure to maintain clearance from powerlines during en route flight.
