ABSTRACT:
A method and apparatus for defueling an aircraft. The apparatus includes a defueling fitting comprising one or more structural connectors, which may include one or more suction cups. The suction cups are disposed in a mount. The suction cups may be raised from a surface in the mount and arranged in a non-circular pattern to facilitate connection to contoured surfaces. An actuator assembly may be attached to the mount for opening an aircraft defueling valve. The suction cups may be operatively connected to a vacuum source to connect the defueling fitting to an aircraft body, with the actuator assembly positioned at the aircraft defueling valve. The defueling fitting facilitates safe and convenient defueling of aircraft, even aircraft with significantly contoured surfaces.
