## Discrepancy

DURING CLIMBOUT, THE FLIGHT CREW REPORTED A BLEED 2 LEAK MESSAGE.  THE FLIGHT CREW DE-SELECTED THE NR 2 BLEED SYSTEM AND THE MESSAGE CLEARED.  THE AIRCRAFT THEN DIVERTED TO KCMH AND LANDED WITHOUT INCIDENT.  DURING TROUBLESHOOTING, MAINTENANCE FOUND THE GROUND AIR CONNECTION CHECK VALVE LEAKING CAUSING THE BLEED LEAK INDICATION.  THE GROUND AIR CONNECTION CHECK VALVE WAS REPLACED AND NO FURTHER DEFECTS WERE NOTED.
