## Discrepancy

FLIGHT ATTENDANTS REPORTED SMOKE IN THE AFT CABIN DURING CLIMB.  COCKPIT CREW DIVERTED THE FLIGHT TO CVG AND LANDED WITHOUT FURTHER INCIDENT.  NO EVIDENCE OF FIRE WAS FOUND AND NO EXTINGUISHERS WERE USED.  MAINTENANCE IN CVG FOUND APU OILCAP LEAKING AND OIL CONTAMINATION ON THE INLET BOX OF THE APU.  THE OIL CAP ASSEMBLY WAS REPLACED AND THE APU INLET ASSEMBLY WAS CLEANED BUT THEY WERE NOT ABLE TO REMOVE ALL OIL CONTAMINATION.
