## Discrepancy

IAH TO STL.  DURING CLIMB THE CREW RECEIVED A BLEED 1 LEAK MESSAGE AT 4,000FT.  THE MESSAGE DISAPPEARED AND THEN RETURNED AT 8,000 FT.  THE AIRCRAFT RETURNED TO FIELD AND LANDED WITHOUT INCIDENT.  MAINTENANCE INSPECTED THE BLEED 1 SYSTEM FOR LEAKS AND REPAIRED A LEAKING JOINT IN THE AFT AVIONICS COMPARTMENT.  AFTER REPLACING THE O-RING IN THE JOINT, THE BLEED SYSTEM OPS CHECKED GOOD.
