Claim Text:
1. An apparatus operable to seal an opening in an aircraft fuel tank during a pressure test of the fuel tank, said apparatus comprising: a substantially dome shaped body comprising a perimeter, said body further comprising a rim extending in an orthogonal direction about the perimeter and a flange extending in a normal direction from said rim and about the perimeter, said body removably coupled to the fuel tank to provide selective access to an interior of the fuel tank; a sealing gasket proximate an intersection of said rim and said flange, extending completely around the perimeter, said sealing gasket oriented to provide a sealing function between the fuel tank and said body as pressure is increased within the fuel tank; and an indicator coupled to said rim and extending about said perimeter of said dome shaped body, said indicator separate from said sealing gasket and comprising at least one band oriented to provide a direct indication of a range of pressurization force within the fuel tank.
