What was found
AIRCRAFT EXPERINCED A SERIES OF FUEL BY-PASS INDICATIONS. DURING THE TROUBLESHOOTING WE DISCOVERED THE FILTERS TO HAVE BEEN CONTAMINATED WITH DIEGME AS A RESULT OF USING AN ANTI-ICE ADDITIVE. I FOLLOWED THE OEM M/M AND REMOVED ALL FUEL PARTS ON ALL THREE ENGINES/APU AND FLUSHED THE AIRFRAME FUEL SYSTEM PER THE OEM TO REMOVE THE CONTAMINATION.
