## Discrepancy

CREW REPORTED, SHORTLY AFTER TAKEOFF A SMOKE ODOR IN THE CABIN AND THE COCKPIT.  A LAVATORY SMOKE INDICATION THEN APPEARED ON THE EICAS.  REPORTED THAT AFTER APPROXIMATELY 30 SECONDS THE ODOR AND THE INDICATION BOTH WENT AWAY.  THE AIRCRAFT LANDED WITHOUT INCIDENT.  MAINTENANCE WAS ABLE TO DUPLICATE THE ODOR AND ISOLATED THE SMELL TO THE LEFT ENGINE BLEED SYSTEM.  REPORTED THAT WITH THE ENGINE BLEED CLOSED, THE ODOR WAS NOT PRESENT.  MAINTENANCE LOCKED THE LEFT ENGINE BLEED SYSTEM CLOSED AND DEFERRED THE ITEM.  THE DEFERRAL WAS CLEARED IN KSDF OF 6/13/2011 WHEN AN OPS CHECK OF THE LEFT BLEED SYSTEM WAS PERFORMED WITH NO DEFECTS NOTED.
