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

The pilot of the helicopter reported that he was departing over a river in dark night conditions when, shortly after takeoff, the helicopter yawed severely to the left. He applied full right anti-torque pedal and the helicopter subsequently impacted the water. The helicopter was not examined after the accident, and the reason for the loss of control could not be determined based on the available information.
