## Discrepancy

DURING CRUISE WITH ANTI-ICE SYS ON, NOTICED A STRANGE ODOR IN CABIN.  WHILE LOOKING INTO CABIN THERE WAS A HAZY SMOKE EMANATING FROM REAR CABIN AROUND LAV AREA.

MX PERFORMED HIGH POWER ENGINE RUNS WHILE CYCLING THROUGH BLEED AIR SOURCES USING VARIOUS TEMP SETTINGS.  COALESCER SOCK IN ACM REPLACED AND ENGS RUN AGAIN USING DIFFERENT BLEED AIR SOURCES & TEMP SETTINGS.  LINES AT ACM & WING ANTI-ICE DUCTS IN LAV WERE INSPECTED WITH NO NOTED DEFECTS.  A CHECK FLT OF THE AIRCRAFT WAS SATISFACTORY AND THE AIRCRAFT WAS RETURNED TO SERVICE.
