FUEL SYSTEM.
At intervals of 50-hours or 90 days, whichever comes first, clean the fuel strainer screen, located in the

Additional fuel system service information may also be found in Chapter 28. Inspection intervals of the
various fuel system components may be found in Chapter 5.
FILLING FUEL TANKS.
Observe all required precautions for handling gasoline. Fill the fuel tanks with the fuel as specified on the
placard adjacent to the filler neck. Each wing tank has a capacity of 38-1/2 U.S. gallons, for a total capacity of
77 U.S. gallons. Five U.S. gallons are considered unusable fuel.
FUEL ANTI-ICING ADDITIVE.
This aircraft is approved for operation with a fuel anti-icing additive. The anti-icing additive used must
meet specification MIL-1-27686 and must be uniformly blended with the fuel while refueling. The additive
must not exceed .15% by volume of the refueled quantity and to ensure its effectiveness should be blended at
not less than .10% by volume (approximately 1 1/2 liquid ozs. per ten gallons of fuel). A blender supplied by
the additive manufacturer should be used. Except for the information contained in this section, the
manufacturer's mixing or blending instructions should be carefully followed.
