The invention concerns a dock for carrying out repair and maintenance work on the outer skin of an aircraft. The dock has two halves (18, 20), it being possible in each dock half to move at least the section (40) lying in front of the wing leading edge or behind the wing trailing edge out to one side beyond the wingtip. Work platforms (24) are mounted on each dock half (18, 20) in such a way that they can be moved parallel to the longitudinal axis of the fuselage, vertically and towards and away from the fuselage skin.
