## Narrative

As the FAA filed it, in capitals; the FAA replaces private details with ^PRIVACY DATA OMITTED^.

THE TAIL ROTOR PITCH CHANGE SHAFT WAS REPLACED 4.6 HOURS PRIOR TO THIS INCIDENT. IT WAS DETERMINED THAT THE PITCH CHANGE BEAM RETAINING NUT AND LOCK WASHER WERE IMPROPERLY INSTALLED AT THAT TIME. DURING FLIGHT THE PITCH CHANGE BEAM RETAINING NUT AND WASHER LOST TORQUE AND SEPARATED FROM THE TAIL ROTOR ASSEMBLY. THE PITCH CHANGE BEAM COULD NO LONGER MOVE WITH THE PITCH CHANGE SHAFT TO APPLY PITCH CHANGES TO THE TAIL ROTOR BLADES CAUSING A LOSS OF TAIL ROTOR AUTHORITY.
