## Discrepancy

BEARINGS WORN.   BELL WAS UNABLE TO SUPPLY TRUNNION BEARING P/N 406-310-405-101, SO PHI ORDERED THE PITCH LINK ASSY P/N 406-010-413-117 INSTEAD.  PHI THEN ROBBED THE BEARING OFF OF THE SERVICEABLE PITCH LINK.  THE UNSERVICEABLE BEARING WAS INSTALLED ON THE SERVICEABLE LINK ASSY, WHICH NOW RENDERS THE LINK ASSY UNSERVICEABLE.
