During cruise flight, the commercial pilot experienced a violent vibration in the airframe followed by a loud "pop" and the helicopter began to yaw to the right. The pilot attempted to correct the adverse yaw but could not regain tail rotor control. The pilot deployed the floatation system and performed an autorotation onto the water. Both pilot and passenger were able to egress the helicopter without incident and entered a life raft. While awaiting rescue the pilot visually inspected the helicopter and could observe no damage or malfunction. A US Coast Guard helicopter crew rescued the pilot and passenger from the water. Prior to recovery, the helicopter capsized due to the rough seas, sank and was not recovered.
Probable Cause: The loss of tail rotor effectiveness for undetermined reasons.
