## Discrepancy

CREW REPORTED THAT THEY RECEIVED A BLEED 1 VALVE FAIL MESSAGE DURING FLIGHT.  THEY FOLLOWED THE QUICK REFERENCE HANDBOOK AND THE VALVE WOULD NOT REOPEN.  THEY RETURNED KCLE AND LANDED WITHOUT INCIDENT.  MAINTENANCE REPLACED THE OVERHEAD PUSHBUTTON SWITCH.  OPERATIONAL CHECKS WERE GOOD WITH NO FURTHER DEFECTS NOTED.
