NTSB Narrative Summary Released at Completion of Accident

The pilot lost directional control of the helicopter while maneuvering and the helicopter impacted water and sank. The pilot was manuevering over a boat race and was flying over the start line about 400 feet agl, on a magnetic heading between 235 to 240. He felt the helicopter drifting north and east. A turn was initiated; however, simultaneously, the helicopter "shuddered and snapped into a rapid right yaw." Left antitorque pedal was applied but the helicopter continued to turn 360 degrees repeatedly while losing altitude. Just prior to impact, the pilot pulled up on the collective and pushed the cyclic into a forward right position intending to assist the main rotor blades in stopping. The Rotorcraft Flying Handbook states that a loss of tail rotor effectiveness (LTE) is the occurrence of an uncommanded yaw rate that does not subside on its own accord, which can result in the loss of helicopter control. The recovery technique for LTE is full left pedal while simultaneously moving cyclic control forward to increase airspeed. If altitude permits, reduce power.

NTSB Probable Cause Narrative

the pilot's inadequate remedial action in response to a loss of tail rotor effectiveness.
