## Discrepancy

CABIN ODOR, FLIGHT ATTENDANT'S STATED PCP ODOR IN REAR,  ROW 22 - 28 WAS THE STRONGEST.   FLIGHT DECK VENT OUTLET HAD A DIRTY SOCK ODOR.  REMOVED AND REPLACED APU GENERATOR IAW AMM 24-23-51 AND CLEANED APU COMPARTMENT AND INLET AS REQUIRED.  OPS AND LEAK CHECKED GOOD. NO ODOR REMAINS IN EITHER PACK SYSTEM.  THE AIRCRAFT WAS GROUNDED.
