## Discrepancy

EICAS BLEED LOSS WING RIGHT INDICATION, FOLLOWED BY RIGHT ISOLATION VALVE CLOSURE, THEN FINALLY THE LOSS OF THE RIGHT AIR CONDITIONING PACK LEAD TO FLIGHT DIVERTING TO MIA.  *S/D*  FOUND FWD BAND CLAMP FAILED AT LWR RT FLOW CONTROL VLV.  THIS CAUSED AIR LEAK, WHICH CAUSED THE RT PACK AND RT BLEED TO SHUTDOWN.  REPLACED CLAMP, THEN A/C RETURNED TO REVENUE SERVICE WITHOUT FURTHER INCIDENT.
