## Discrepancy

COCKPIT FILLED WITH SMOKE ON UPWIND CLIMB - NOTED THAT THE APU OIL QUANTITY WAS LOW. SERVICED APU OIL TO FULL, PERFORMED GROUND POWER RUNS WITH ACM (PACK)- ON, INSPECT WATER SEPARATOR SOCK FOR OIL CONTAMINATION.  PERFORMED APU / ENGINE GROUND RUNS UTILIZING DIFFERENT BLEED AIR SOURCES, THEN MEL APU FOR MAINTENANCE FLIGHT.  INSPECT APU COMPRESSOR (BORESCOPE)- NO AMORALITIES NOTED.  CONTINUE "NORMAL OPERATIONS" PER HONEYWELL APU SUPPORT.
