3. DESCRIPTION A. Fuel tank (Figures 1 and 1A)
Each fuel tank is equipped with its own air vent system, an essential element in the operation of the fuel system. Should a vent become blocked, the fuel flow from the related tank is reduced and the engine may cut out. The air vent is ensured by ducts which run to the lower surface of each wing.
The air vent system enables tank ventilation to avoid tank distorsion due to pump suction. The vent hose has no check valve, because of the respective position of the tapping (high point in the fuel tank, except fuel in horizontal flight) and of the discharge at wing lower surface, on wing root side (higher than fuel level in the fuel tank when the aricraft is turning).
NOTE : Fuel could flow out of the vent system when the aircraft is parked on an uneven surface
with full tanks. This disadvantage is increased when parked by hot weather.

This type of fuel tank is built in as part of the wing structure. Tank is sealed during construction by applying sealant between skins and ribs or spars. This sealant is also applied to the rivets when they are installed in the wing. Access to the inside of the tank can be gained through two inspection panels (tight doors) located on the bottom side of each fuel tank.
