maximum of 150 hours between overhauls. For the Restricted Category, service
the aircraft with Jet A, Jet B, JP-4, JP-5, or automotive diesel number 1D or 2D in
accordance with P&WC Specifications CPW204, CPW 46 and CPW 381.
Automotive diesel fuel is approved only for flights when the free air temperature
is above +20 degrees Fahrenheit use grade #1D or +40 degrees Fahrenheit use
grade #2D.
Ground the aircraft and the fuel servicing
equipment to the aircraft. Smoking in or around
the aircraft during refueling operations is
prohibited. Fire protection equipment must be
immediately available.
1. Turn all the switches off.
2. Remove the fuel filler cap. Fill the tank until the fuel level rises to the filler
neck. Install the fuel filler cap and service the opposite fuel tank.
As the wing tanks are interconnected through
the header tank, the fuel can flow from one tank
to another. Topping off both wing tanks may be
required more than one time to assure that both
wing tanks are full.
3. After fueling is complete, check for security of both fill port caps. Wash any
spilled fuel from the wing surface with clean water.
B. Three fuel drain points are provided to allow fuel draining in order to extract the
moisture and sediment entrapped in the system. The drains are located at the
bottom of each wing tank, the header tank, and firewall fuel filter (Fig. 2-3). Also
provided are two fuel vent drains, located on each side of fuselage under the
wings (see Fig. 2-4). Finally, a drain port is provided to drain the residual fuel
reservoir. At engine shutdown, fuel from the flow divider/dump valve, located at
the 6 o'clock position on the engines fuel nozzle manifold, is directed to a
residuel fuel reservoir "EPA tank" located on the L/H cowl shin skin.
reservoir holds approximately 3 engine shutdowns worth of fuel before the fuel
will exit the reservoirs' vent system. All fuel drains should be drained prior to the
first flight of the day. Drain a small quantity of fuel into a transparent container to
permit inspection for the presence of moisture or sediment. The fuel should then
be drained until all evidence of moisture or sediment disappears.
The residual fuel reservoir (EPA tank) should be
emptied after each engine shutdown.
