2. Fuel System
At intervals of 50 hours or 90 days, whichever comes first, clean the fuel strainer screen, located in the
fuel bowl mounted on the lower right side of the forward baggage compartment, below the floors, and
clean the screen in the inlet side of the injector. Remove and clean the fuel strainer screen in
accordance with the instructions outlined in 28-00-00. Additional fuel system service information may
also be found in Chapter 28. Inspection intervals of the various fuel system components may be found in
5-20-00.
A. Filling Fuel Cells
WARNING: DURING FUEL SYSTEM MAINTENANCE PRACTICES, A GROUND WIRE
ATTACHED FROM EACH MAIN GEAR GROUNDING PIN TO SEPARATE APPROVED
GROUNDING STAKES SHOULD BE USED TO PREVENT UNGROUNDING OF THE
AIRCRAFT DUE TO ACCIDENTAL DISCONNECTION OF ONE GROUND WIRE.
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 61 U.S. gallons, for a
total capacity of 122 U.S. gallons. Two U.S. gallons are considered unusable fuel.
B. Draining Moisture From Fuel System
CAUTION: WHEN DRAINING ANY AMOUNT OF FUEL, CARE SHOULD BE TAKEN TO
ENSURE THAT NO FIRE HAZARD EXISTS BEFORE STARTING THE ENGINE.
The fuel tanks and fuel strainer should be
drained daily prior to first flight and after
refueling to avoid the accumulation of water
or sediment. Each fuel header tank is
equipped with an individual quick drain
located at the lower inboard rear corner of
the tank. The fuel strainer with a quick drain
valve is located on the lower right side of the
forward baggage compartment. Drain fuel
tanks and strainer per the following:
(1) Drain each tank through its individual
quick drain located at the lower inboard
rear corner of the header tank, making
sure that enough fuel has been drained
to ensure that all water and sediment is
removed.
(2) Place a container under the fuel strainer
drain. Drain the fuel strainer by opening
the quick drain on the strainer.
(3) Examine the contents of the container
placed under the fuel strainer drain for
water and sediment, then dispose of the
contents.
(4) After refueling, delay sump sampling by
several minutes. This will permit water
and contaminants to flow to the sump
drains for detection.
