Zusammenfassung:	A stairway assembly is pivoted between deployed and stowed positions. The stairway in one form includes a sliding support from which the stairway is suspended at a location spaced from a stairway pivot. A link, which may be adjustable in length, couples the coupler to the stairway. A snubber is provided to limit vibration of the stairway when stowed. An actuator, which may comprise an electric motor, is positioned above and overlies a portion of a platform of the stairway. Extension and retraction of the actuator pivots the stairway between stowed and deployed positions.
