## Discrepancy

FLIGHT CREW REPORTED A BLEED 1 LEAK MESSAGE DURING FLIGHT AND RETURNED TO IND AND LANDED WITHOUT INCIDENT.  MAINTENANCE DEFERRED THE ENGINE 1 BLEED SYSTEM AND RETURNED THE AIRCRAFT TO SERVICE.  THE MEL WAS CLEARED IN SDF ON 8/29/2010 WHEN THE O-RINGS AT JOINTS 3 AND 17 WERE FOUND TO BE LEAKING AND WERE REPLACED.
