SECTION 7
DESCR/OPERATION
Manually controlled flaps are provided. They are extended by a control
cable and are spring-loaded to the retracted (up) position. The control is
located between the two front seats on the control console (Figure 7-9). To
extend the flaps pull the handle up to the desired flap setting of 10. 25. or 40
degrees. To retract. depress the button on the end of the handle and lower the
control.
The airplane will experience a pitch change during flap extension or
retraction. This pitch change can be corrected by either stabilator trim or
increased control wheel force. When the flaps are in the retracted position
the right flap, provided with a over-center lock mechanism. acts as a step.
NOTE
The right flap will support a load only in the
fully retracted (up) position. When loading and
unloading passengers make sure the flaps are in
the retracted (up) position.
7.15 FUEL SYSTEM
The fuel system was designed with simplicity in mind. Fuel is contained
in two 38.5 U.S. gallon tanks. one in each wing. Of the total 77 gallon
capacity. Qnly 72 gallons are usable. Each tank is equipped with a filler neck
indicator tab to aid in determining fuel remaining when the tanks are not
full. Usable capacity tab to the bottom of the indicator tab is 25 gallons. The
minimum fuel grade is 100 octane (green) or looLL (blue). The tanks are
attached to the leading edge of the wing with screws and are an integral part
of the wing structure. This allows removal for service. The tanks are vented
individually by a vent tube which protrudes below the bottom of the wingat
the rear inboard corner of each tank. The vents should be checked
periodically to ensure they are not obstructed and will allow free passage of
air.
Each fuel tank has an individual quick drain located at the bottom
inboard rear corner. The fuel strainer also incorporates a quick drain.
located on the left lower portion of the firewall. The quick drain protrudes
thru the cowling to allow easy draining of the fuel strainer. To avoid the
accumulation of water and sediment. and to check that the tanks contain the
proper grade fuel, the fuel tank sumps and strainer should be d rained daily
prior to first flight and after refueling.
