## Discrepancy

WHILE CLIMBING THROUGH 8,000FT, A BLEED 1 LEAK MESSAGE WAS DISPLAYED ON EICAS.  THE CREW FOLLOWED THE QRH AND RETURNED TO IAH AND LANDED WITHOUT INCIDENT.  WHILE INSPECTING THE BLEED 1 SYSTEM FOR LEAKS, MAINTENANCE FOUND THE T DUCT FROM THE BLEED VALVE TO APU CRACKED AND BLEED JOINT 9 LEAKING.  THE T DUCT WAS REPLACED ALONG WITH THE O-RING AT JOINT 9.
