## Discrepancy

CREW IDENTIFIED WINDSCREEN OVERHEAT ANNUNCIATOR LIGHT ILLUMINATED INTERMITTENTLY DURING FLIGHT.  MAINT REPLACED WINDSHIELD ANTI-ICE VALVE WITH NEW STYLE VALVE.  LEAK AND OPS CHECK WERE SATISFACTORY.  AFTER CONTACTING THE OEM, THEY CONFIRMED AN IMPROVED VALVE WAS AVAILABLE.  THIS IS THE PRODUCT WE INSTALLED.
