Confidence Rating: Accident investigation report completed and information captured
Narrative:
The pilot reported that before he began his first aerial application run, he flew overhead to scout the designated field for hazards and noted a power line near the field. He stated that he had a "momentary lapse" during his first application pass and flew through the wires, which shattered the cabin's main Plexiglass bubble and struck the main rotor mast. Both push-pull flight control tubes were compromised just above the swashplate. The helicopter fell to the ground and came to rest upright on its landing skids. The pilot reported no preimpact mechanical malfunctions or failures with the helicopter that would have precluded normal operation.

Probable Cause: The pilot's inadequate monitoring of the environment and failure to maintain clearance from transmission wires during a low-altitude maneuver.
