## Discrepancy

THE FLIGHT CREW REPORTED THAT THE LEFT ENGINE ANTI-ICE "LO TEMP" ANNUNCIATOR CONTINUOUSLY FLICKERS WHILE IN USE. THE MAINTENANCE TEAM TROUBLESHOT AND FOUND THE LEFT ENGINE ANTI-ICING VALVE DEFECTIVE. THE VALVE WAS REMOVED AND AN OVERHAULED VALVE WAS INSTALLED. GROUND RUN, LEAK CHECKS AND OPERATIONAL CHECKS WERE SATISFACTORY.
