Abstract
An assembly for use on an aircraft wing having an aircraft skin and a fuel tank, the assembly comprising a metal access door for accessing the fuel tank, a metal retainer ring for engaging the wing and the access door. Fasteners removably couple the access door to the retainer ring. A lip, which may be on the wing surface, is configured to receive a perimeter of the access door when the access door is coupled to the retainer ring. A polyurethane elastomeric gel gasket having a metallic skeleton is configured to lay between the access door and a lip of the metal wing surface. Under compression, the polyurethane will deform and squeeze out the edges and flatten so as to provide metal-to-metal contact between the access door and the lip.
