## Discrepancy

FLT 544 PDX-PHX - CABIN ODOR - CABIN HAS VERY BAD DIRTY SOCK SMELL COMING FROM PACKS, FIRST ON TAKEOFF, THEN AGAIN ON DESCENT INTO PHX.  SMELL IS WORSE WITH THE ENGINE HP VALVES OPEN.  APU WAS DETERMINED TO BE THE SOURCE.  MAINTENANCE REMOVED AND REPLACED THE APU.   VENDOR REPORT INDICATES WHITE STREAK RESIDUE FOUND IN BLEED DUCT, POSSIBLY FROM ON-WING WASH - OIL FILM RESIDUE FOUND IN INLET PLENUM DOES FLUORESCE LIKE APU OIL - SUSPECT FOREIGN OBJECT INGESTION.
