## Discrepancy

(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.
