Abstract: A method for easily removing portions of aircraft skin damaged by pressure cycles and corrosion. The method includes inspecting both upper and lower portions of the skin. Using a special router and guide, the damaged skin is then removed and replaced. The method is particularly useful in that it is rapid and precise, and promises control over the process sufficient to insure that aircraft structure below the skins is not damaged. The method may also be used to remove and replace sheet metal used in other applications.

Abstract: An apparatus for easily removing portions of aircraft skin damaged by pressure cycles and corrosion includes a router and a guide for the router. The guide is precisely formed for a uniform height or thickness. Using this thickness, a router with a precise vertical adjustment rides on a platform above the aircraft, guided by the guide, and quickly and easily makes long horizontal cuts to remove layers of aircraft skin that contain cracks or corrosion. The apparatus may also be used for removing and replacing sheet metal used in other applications.
