## Discrepancy

TAIL ROTOR PITCH BEAM WAS FOUND LOOSE ON PITCH SHAFT, WITH .1250 INCH GAP BETWEEN WASHER-RETAINER AND NUT.  INSPECTION REVEALED PITCH BEAM NUT WAS BOTTOMING OUT ON PITCH SHAFT, PREVENTING PITCH BEAM AND WASHER FROM SEATING.  THE PITCH SHAFT HAD 80 HOURS SINCE INSTALLATION WITH TAIL GEARBOX (NUT WAS PROPERLY TORQUED).  REPLACED PITCH SHAFT ASSY, PITCH BEAM, AND WASHER-RETAINER.
