Fuel system
The airplane has a fuel tank located in the inside leading edge of each wing.
Each tank is equipped with a vent (underneath wing) and finger screen (on
tank outlet). A drain valve is located at the lowest point of each tank. Tank
outlets lead to a fuel selector valve situated on the central console in the
cockpit. Fuel return lines return excess fuel supplied by the fuel pump to the
fuel tank in use. The system is configured as in the diagram below.
Volume of wing tanks: 2 x 75 litres (2 x 19.8 US gal), (73 litres / 19.2 US gal
useable per tank).
WARNING
The fuel lift pipe in each fuel tank is situated adjacent to the lower
inside wall of the tank. The aircraft should at no time be subjected to a
sustained side slip towards a near empty fuel tank which is in use (i.e.
wing with near empty tank down) as, despite the baffling, this may have
the consequence that the fuel runs towards the outer edge of the tank
exposing the fuel lift pipe to suck air, thereby starving the engine of fuel
leading to engine failure. This poses a particular threat when at low
altitude, typically prior to landing.
