NTSB Narrative Summary Released at Completion of Accident

According to a representative from the operator, the pilot and spotter were conducting fish-spotting duties, and the helicopter was in a cruise flight about 600 feet above the water when the pilot felt a vibration through the tail rotor pedals. The pilot descended to about 15 feet above the water; the helicopter yawed right, contacted the water, and rolled over. The pilot and spotter exited the helicopter and were later rescued by a fishing vessel; however, the spotter died the following day. The helicopter’s tail boom and tail rotor assembly were not located and presumably sank. Sections of the fuselage and main rotor assembly were recovered but were disposed of before investigative personnel could examine them.

NTSB Probable Cause Narrative

A loss of helicopter control for undetermined reasons.
