What was found
(AUS) FUEL SYSTEM CONTAMINATED WITH ETHYLENE DIAMINE (EDA). FOLLOWING DECONTAMINATION WASH, WATER WOULD NOT DRAIN FROM THE TANKS. A PROBE INSERTED VIA THE WATER DRAIN PORT RESULTED IN A DIAPHRAGM BEING FELT. THE DIAPHRAGM WAS PUNCTURED TO DRAIN THE WATER. THIS WAS CARRIED OUT NUMEROUS TIMES BEFORE THE TANKS WERE FULLY DRAINED. DURING THE DRAIN A GREEN TRANSLUCENT GEL APPEARED. A SAMPLE WAS TAKEN BUT APPAREENTLY EVAPORATED OVER A THREE DAY PERIOD. ABOUT THREE TO FOUR DAYS LATER A TREACALY BROWN SUBSTANCE WAS FOUND ON THE BOTTOM OF THE TANKS.
