## Discrepancy

DURING CUSTOMER BOARDING, THE CABIN CREW NOTICED SMOKE IN THE CABIN.  THE AIRCRAFT WAS DEPLANED NORMALLY THROUGH THE MAIN CABIN DOOR AND JET BRIDGE.  CORRECTIVE ACTION: MAINTENANCE FOUND THAT THE APU WAS LEAKING OIL AND REPLACED THE APU.  A DUCT BURNOUT WAS ACCOMPLISHED.  THE AIRCRAFT HAS RETURNED TO SERVICE.
