The NTSB's narrative final · quoted from the NTSB record

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."
