Read the full NTSB narrative
The helicopter collided with power lines during aerial application operations. The pilot was returning to the service truck for another load [of chemicals]. At the top of a ridge, approximately 500 feet mean sea level, there were two power lines of which he was unaware. During a descent at 60 knots, the helicopter impacted the top wire "about the middle of the bubble." As a result, it pitched forward and the main rotor blade cut the wire and tail boom off in sequence. The helicopter began spinning to the right and the pilot performed an autorotation.
