While in cruise flight the helicopter sustained the loss of the entire tail rotor system. The helicopter landed successfully with no additional damage or any injuries. Examination revealed the loss was initiated by a fatigue crack in the skin of one of the tail rotor blades. The manufacturer determined that a manufacturing process used in making the blades initiated the fatigue failure due to a grinding process which removed material from the tail rotor skin.
Probable Cause: the manufacturer's inadequate quality control which led to a fatigue failure of the tail rotor blade.
