## Discrepancy

CREW REPORTED, RECEIVED A BLEED 2 VALVE CLOSED MESSAGE IN FLIGHT.  THE CREW FOLLOWED THE QUICK-REFERENCE HANDBOOK BUT THE VALVE WOULD NOT INDICATE OPEN.  THE AIRCRAFT RETURNED TO FIELD AND LANDED WITHOUT INCIDENT.  MAINTENANCE REPLACED THE BLEED 2 PUSHBUTTON SWITCH.  OPERATIONAL CHECKS WERE GOOD WITH NO FURTHER DEFECTS NOTED.
