## Discrepancy

WHEN THE CREW ATTEMPTED A CROSS BLEED START ON THE NR 1 ENGINE, THE SMOKE AFT LAV WARNING MESSAGE ILLUMINATED AND A FLIGHT ATTENDANT REPORTED FUMES FROM FLOOR VENTS.  THE CREW DECLARED AN EMERGENCY AND EVACUATED THE AIRCRAFT.  MAINTENANCE FOUND THE RT AIR CYCLE MACHINE TURBINE SEIZED.  THE ACM WAS REMOVED & REPLACED IAW CRJ700 AMM 21-51-08-400-801-A01.  OPERATIONAL AND LEAK CHECKS WERE GOOD.  THE AIRCRAFT WAS THEN RELEASED FOR SERVICE.
