Abstract
Aircraft cabin stairs to connect the aircraft fuselage to a parking area surface gave a frame comprising at least two telescoping segments as well as steps located in the region of the frame. An end segment forms part of the frame by means of side stringers which are present at least in certain regions and which are connected in a telescoping manner to side stringers of a main segment. At least one step in the region of the main segment is mounted such that it is free to slide in the direction of the stairs' longitudinal axis.
