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

The helicopter was in a 4-to 6-foot hover above the marsh's surface, maneuvering for film shooting. The pilot stated the helicopter began to spin clockwise despite his applying full left anti-torque pedal. Increasing collective did not remedy the uncommanded yawing, so he lowered collective and power, and settled into the marsh, collapsing the left skid and the three occupied seats. The tail boom was severed by a main rotor blade strike. Winds were from the south to southwest at 15 knots. Examination of the wreckage revealed no evidence of precrash failure or malfunction of the helicopter's flight controls, structure, or rotor drive system.
