| Confidence Rating: |  Accident investigation report completed and information captured |
Three witnesses saw the helicopter hovering and the rotor wash stirring up dust. One of those witnesses and another witness observed the helicopter turn, start to fly away, collide with two power lines, and subsequently hit the ground and bounce. The dust likely obscured the pilot's visibility while he was maneuvering the helicopter near the ground and led to his failure to see and avoid the power lines.
Probable Cause: The pilot’s failure to see and avoid power lines while maneuvering near the ground because dust stirred up by the rotor wash obscured his visibility.
