CS 22.967 Fuel tank installation ED Decision 2003/13/RM (a) Each fuel tank must be supported so that the loads resulting from the weight of the fuel are not concentrated. In addition: (1) there must be pads, if necessary, to prevent chafing between each tank and its supports; and (2) materials employed for supporting the tank or padding the supporting members must be non-absorbent or treated to prevent the absorption of fuel. (b) Each tank compartment must be ventilated and drained to prevent accumulation of flammable fluids and vapours. Each compartment adjacent to a tank must be treated in a similar manner. (c) No fuel tank may be located on the engine side of the firewall. There must be at least 15 mm of clearance between the fuel tank and the firewall. (d) If the fuel tank is installed in the personnel compartment, it must be demonstrated that adequate ventilation and drainage are provided, that the presence of the tank will in no way interfere with the operation of any part of the powered sailplane, or the normal movement of occupants, and that no leaking fuel will fall directly on to any occupant. (e) Fuel system components which could cause leakage of fuel as a result of a wheels-up landing must be suitably protected from damage.
