## Discrepancy

DURING DESCENT CREW SMELLED SULPHUR ODOR IN ACFT.  UPON DEBARKATION OF PASSENGERS, CABIN FILLED WITH SMOKE, STARTING FROM THE REAR OF THE ACFT.  ON INSPECTION OF A/C PACKS, IT APPEARS BOTH "ACM OIL RESERVOIRS" WERE BLACK - WHICH AT THE BEGINNING OF THE FLIGHT WAS NOT THE CASE.  REMOVED CABIN ACM AND INSTALLED A REPAIRED UNIT.  OPS CHECKED GOOD.  WORK PERFORMED IAW MM 21-51-00.
