## Discrepancy

CREW REPORTED A BLEED 2 LEAK MESSAGE AFTER TAKEOFF.  THE QRH WAS FOLLOWED AND AFTER CLOSING THE NR 2 BLEED, THE MESSAGE CLEARED.  THE AIRCRAFT RETURNED TO JFK AND LANDED WITHOUT INCIDENT.  MAINTENANCE FOUND THE DUCT AND JOINT AT THE GROUND AIR CONNECTION LEAKING.  THE O-RINGS AND DUCT AT THE GROUND AIR CONNECTION WERE REPLACED WITH NO FURTHER DEFECTS NOTED.
