A design and installation method are provided to improve access to equipment mountable on aircraft equipment racks, including installing modified equipment rack framework on the aircraft, preassembling the equipment on a separate equipment package, providing separate matable hinge units on both the framework and equipment package, and temporarily supporting the equipment package in a hanging position from the equipment rack by matably joining the separate hinge units. Wiring the equipment from adjacent wireway banks is performed in the hanging position, followed by rotating the equipment package about an axis of rotation formed by the joined hinge units into a fixed stowed position, and fastening the equipment package to the equipment rack framework to complete the installation.
