## Discrepancy

CLE FLIGHT 2351 - CREW REPORTED BOTH ENGINE BLEEDS CLOSED ADVISORY MESSAGE AND BOTH PACKS CLOSED, ADVISORY MESSAGE ON EICAS AFTER TAKEOFF.  THE AIRCRAFT RETURNED TO CLE AND LANDED WITHOUT INCIDENT.  MAINTENANCE INSPECTED AND REPLACED TWO PACK COUPLINGS FOR PACK NR 1 AND ONE COUPLING FOR PACK NR 2.  OPERATIONAL CHECKS WERE GOOD AND AIRCRAFT RETURNED TO SERVICE.
