## Discrepancy

STRANGE ODOR IN AIRCRAFT, VARIES FROM DIRTY SOCKS TO VOMIT.  ODOR INCREASE FURTHER AFT IN CABIN.  FUME IS VERY IRRITATING TO EYES AND THROAT.  FOUND OIL LEAKING AT PRESSURE FILTER AT DELTA P SWITCH ASSEMBLY.  REMOVED AND REPLACED APU LOW PRESSURE SWITCH PER AMM 49-94-14-0401.  OPS CHECKED GOOD.
