the airbus a300 was to be the first aircraft to be developed, manufactured and marketed by airbus. by early 1967 the "a300" label began to be applied to a proposed 320 seat, twin engined airliner. following the 1967 tri-government agreement, roger béteille was appointed technical director of the a300 development project. béteille developed a division of labour that would be the basis of airbus' production for years to come: france would manufacture the cockpit, flight control and the lower centre section of the fuselage; hawker siddeley, whose trident technology had impressed him, was to manufacture the wings; west germany should make the forward and rear fuselage sections, as well as the upper centre section; the dutch would make the flaps and spoilers; finally spain (yet to become a full partner) would make the horizontal tailplane. on 26 september 1967 the west german, french and british governments signed a memorandum of understanding in london which allowed continued development studies. this also confirmed sud aviation as the "lead company", that france and the uk would each have a 37.5% work share with west germany taking 25%, and that rolls-royce would manufacture the engines.
