Analysis

The helicopter ditched in the Ocean after sustaining a flameout. After the helicopter was towed ashore on its floats the fuel system was found to contain at least 4 gals of fuel. Info contained in helicopter manual revealed all fuel was usable except about 1 gal; therefore fuel exhastion was not in evidence. An exam of the helicopter fuel system revealed foreign matter. An exam of the fuel truck that refueled the helicopter and the fuel tank storage farm where truck obtained its fuel revealed foreign matter of similar appearance. A laboratory analysis of the fuel samples from the helicopter and refueling source revealed that they were chemically the same.
