Abstract: The invention is a mobile maintenance stand that combines the function of an adjustable stairway and hydraulic scissor lift that independently elevates and descends an access work platform to support maintenance tasks on commercial and military aircraft. The elevating access work platform has an extended reach of 144? and is initiated by a secondary hydraulic scissor lift that promotes upward extension beyond the parameters of the adjustable stairway reach, to provide further maintenance access. The additional extension range of the access work platform with a hydraulic scissor device, provides vertical movement to the work deck at all check levels. Further, this invention is self-contained that collapses to a compact dimension and be transported on an air cargo pallet. Thus, the invention's mechanical scheme of the scissor lift to extend access work platform beyond the adjustable stairway is novel and, is unlike any existing articulating stairway and, or scissor embodiments.
