## Discrepancy

TROUBLESHOT INOPERATIVE RT ENG NACELLE INLET HEAT INDICATION AT IDLE. FOUND RT NACELLE INLET HEAT PRESSURE REGULATING/SHUTOFF VALVE FAILED. VALVE WAS INSTALLED 1/19/2010, AFTER O/H, REPLACED VALVE ASSY WITH ANOTHER O/H VALVE ASSY AND FUNCTIONAL CHECKS ON ENG GROUND RUN OPERATIONS WERE NORMAL. HAVE REPLACED NUMEROUS "0" TIME SINCE O/H PN 5188-00-1 ENGINE ANTI-ICE VALVES THIS FALL/WINTER SEASON FROM SAME FACILITY THAT HAVE FAILED AT INSTALLATION OR SHORTLY THEREAFTER. RECOMMEND MFG SERVICE FACILITY INVESTIGATE WHETHER THIS IS A QUALITY CONTROL ISSUE OR IF COMPONENT O/H SPECS NEED TO BE REVISED.
