## Discrepancy

THE FLIGHT CREW REPORTED THAT THEY HAD A LEFT HIGH PRESSURE BLEED AIR VALVE FAIL INDICATION.  THIS CAUSED A LEFT ENGINE ANTI-ICE COLD INDICATION.  THE MAINTENANCE VENDOR DETERMINED THAT THE LEFT HP VALVE WAS DEFECTIVE AND REPLACED THE UNIT WITH AN OVERHAULED UNIT.  OPERATIONS CHECKS SATISFACTORY.  THE AIRCRAFT WAS RETURNED TO SERVICE.
