ABSTRACT:
A defueling fitting is adapted to facilitate removal of fuel from an aircraft fuel cell through a flush-mounted fuel drain having a depressable valve stem. It includes a flange with spaced circumferential seals. A vacuum outlet leads between the seals to facilitate attachment of the flange to an exterior aircraft surface surrounding a fuel drain. A separable probe includes a pin actuator for depressing the valve stem of the fuel drain and one or more liquid passages for directing draining fuel through the flange through an attached hose. The method for defueling involves first attaching the flange to the aircraft surface surrounding a fuel drain by application of reduced pressure between the circumferential seals and subsequently depressing the valve stem of the fuel drain to direct fuel through an enclosed liquid passage.
