## Discrepancy

ON FLIGHT 3864 THE CREW REPORTED SMOKE IN AFT CABIN ON APU RESTART. THE AIRCRAFT CAME FROM THE DE-ICE PAD.  THE AIRCRAFT WAS REMOVED FROM SERVICE.  PERFORMED OPERATIONAL CHECK OF THE APU.  ALL PARAMETERS WERE NORMAL.  RAN APU AND PACK FOR 1 HOUR, ALL EVIDENCE OF SMOKE AND ODOR DISSIPATED.  SUSPECT DE-ICE FLUID IN APU INLET.  OK FOR SERVICE.  THE AIRCRAFT WAS RETURNED TO SERVICE.
