## Discrepancy

CREW REPORTED THEY RECEIVED THE BLEED 1 VALVE FAIL MESSAGE IN FLIGHT.  THE CREW FOLLOWED THE QUICK REFERENCE HANDBOOK AND RETURNED TO FIELD AND LANDED WITHOUT INCIDENT.  MAINTENANCE REPLACED THE COUPLING TO TEMPERATURE CONTROL VALVE AND OPERATIONAL CHECKS WERE GOOD WITH NO FURTHER DEFECTS NOTED.
