Abstract: A bolted joint for connecting a cover of an opening in a primary structure of a lifting surface of an aircraft to the primary structure. The bolted joint includes two first bolted joints on either side of a symmetry axis of the cover arranged without any lateral clearance, two second bolted joints on either side of the symmetry axis on the side of the cover opposite to that of the two first bolted joints, arranged without any lateral clearance in the holes of the primary structure and with a linear lateral clearance in the holes of the cover; a plurality of third bolted joints along the border of the cover arranged without any lateral clearance in the holes of the primary structure and with a radial clearance in the holes of the cover.

Abstract: An outer fuel access tank cover (FTAC) of an aircraft, a wing comprising such outer FTAC of an aircraft and an aircraft are provided. In one example, an outer fuel tank access cover (FTAC) (4) of an aircraft includes an inner surface and an outer surface. The outer FTAC is to cover the outer opening of a void area of a manhole for accessing the interior of a wing of an aircraft in which the interior of the wing comprises a fuel tank. The outer FTAC comprises absorption means adapted for absorbing the impact energy due to an object impacting against the outer FTAC.
