Abstract:

An aircraft passenger window maintenance shield is provided to form a protective barrier about an aircraft window to prevent damage to the area surrounding the window during a window outer pane external surface repair procedure involving rotary power equipment. Two generally rectangular panels each having a generally half-window shaped opening are slidingly interfit with one another and snap-fit onto the window frame in such a fashion as to form an aircraft window shaped opening in the area of the aircraft window. The two panels interfit such that a first overlapped edge of the first panel is overlapped by a second overlapping edge of the second panel, and a second overlapped edge of the second panel is overlapped by a first overlapping edge of the first panel. In this fashion, the rotary power equipment is not damaged by the panels, nor are the panels pulled apart by the action of the rotary power equipment. The panels are bent in a slightly arcuate fashion to conform to the slight arc of the outer aircraft surface.
