## Discrepancy

DURING THE FIRST FLIGHT SINCE ENG FLUSH, THE COCKPIT & CABIN FILLED WITH SMOKE.  THE SMOKE WAS CONSISTENT WITH THE SMELL FROM RUNNING THE HEATER AFTER AN ENG FLUSH.  INSPECTED BOTH ENGS FOR LEAKS & BURNED WIRING WITH NO DEFECTS NOTED.  THIS WAS THE FIRST FLIGHT AFTER ENG & COMPRESSOR WASHES FOR EACH ENG.  THEN GND RAN WHILE THE MX INSPECTED & FOUND EVIDENCE OF COMPRESSOR SOAP BURN OFF.  THE ACFT WAS SHUT DOWN ONCE ALL OF THE SOAP RESIDUE HAD BEEN COMPLETELY BURNED OFF.  PERFORMED A CHECK FLIGHT TO CONFIRM THE SMELL & SMOKE HAD DISSIPATED.  AFTER SHUTDOWN VISUALLY INSPECTED ENGS & ENG COMPARTMENTS.  NO LEAKS OR BURNED WIRING WERE FOUND.  AT THIS TIME, THE ACFT WAS RETURNED BACK TO SERVICE.
