## Discrepancy

PITCH LINK REMOVED, P/N 406-310-405-101, S/N RXFS-4567, TT 174:35 HOURS, DUE TO BEING WORN.  BELL WAS UNABLE TO SUPPLY TRUNNION BEARINGS P/N 406-310-405-101, SO PHI ORDERED THE PITCH LINK ASSY P/N 406-010-413-117 INSTEAD.  PHI THEN ROBBED THE SERVICEABLE BEARINGS RXFS-4421 OFF THE SERVICEABLE PITCH LINK.  THE UNSERVICEABLE BEARING RXFS-4567 WAS INSTALLED ON THE SERVICEABLE LINK ASSY, WHICH NOW RENDERS THE LINK ASSY UNSERVICEABLE.
