Aircraft Accident/Incident Report

Medora, North Dakota 58645
Thursday, October 18, 2007 11:05 MDT

NTSB Narrative Summary Released at Completion of Accident

The pilot lost control of the helicopter and it impacted the terrain after a skid caught the top of a wire fence. The helicopter was being used for a herding mission when the left skid caught the top wire of a ten foot high fence. The helicopter began a dynamic roll to the left and impacted the ground. The pilot reported trying to counteract the roll by "reducing the power and adjusting the cyclic but was unsuccessful."

NTSB Probable Cause Narrative

The pilot failed to maintain clearance from the fence while maneuvering at a low altitude, which resuled in the helicopter rolling over and impacting the terrain. A factor associated with the accident was the fence.
