2.3.2.2
Special Precautions for Aviation Turbine Fuels.
Because of the serious consequences of a turbine engine
failure and the nature of the fuel systems in turbine engines,
provide designs which include means to prevent contamination
of aviation turbine fuels by dirt, water, or other types of
fuels. Solid contaminants are generally those which are
insoluble in fuel. Most common are iron rust, scale, sand,
and dirt. Iron rust contaminates aviation turbine fuel, and
carbon steel contact degrades thermal stability. Special
filtration is required for receiving aviation turbine fuel
into bulk storage and ready issue (operating storage) to
remove contaminants before the fuel is delivered to aircraft.
To preserve fuel quality, limit materials in contact with the
fuel to stainless steel, non-ferrous, or coated carbon steel
for aircraft fueling systems. Do not use zinc, copper, and
zinc- or copper-bearing alloys in contact with aviation
turbine fuels, including pipe, valves, equipment, and
accessories. The maximum allowable aircraft servicing use
limits of solids is 2.0 mg/L and the maximum allowable
aircraft servicing use limits of free water is 5 ppm. Provide
a design that precludes disposing of aviation turbine fuels
into storm or sanitary sewers.
