FUEL SYSTEM
The system is equipped with two aluminum fuel tanks integrated within the wing
leading edge and accessible for inspection through dedicated covers. Capacity of
individual tank is 35lt (45lt optional) and total usable fuel is 66.8lt (86.8 lt).
Each fuel tank is equipped with a cabin installed shutoff valve. A strainer cup
with a drainage valve (Gascolator) is located on the engine side of the firewall.
Fuel level indicators for each tank are located on instrument panel. Fuel feed is
through an engine-driven mechanical pump and through an electric pump for
emergencies (normally ON for takeoff) that supplies adequate engine feed in
case of main pump failure. All fuel lines located in the engine compartment are
protected with fireproof braiding to avoid possible fire. Figure 7-3 illustrates the
schematic of the fuel system.
