## Discrepancy

THE INBOUND CREW REPORTED AN "ACRID SMELL" AND "HAZE" IN THE CABIN.  UPON ARRIVAL, MAINTENANCE FOUND THE APU WAS OVER-SERVICED AND THE OIL CAP WAS LEAKING.  APU SERVICED TO  CORRECT LEVEL AND OIL CAP REPLACED.  A DUCT BURNOUT WAS SATISFACTORILY PERFORMED AND NO FURTHER SMELL WAS NOTED.  THE AIRCRAFT HAS RETURNED TO SERVICE.
