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.

An outer fuel tank access cover for covering an outer opening of a void area of a manhole for accessing an interior of a wing of an aircraft that includes a fuel tank, the outer fuel tank access cover comprising:
- an inner surface, and
- an outer surface,
- wherein the outer fuel tank access cover comprises absorption means for absorbing the impact energy due to an object impacting against the outer fuel tank access cover.
A wing of an aircraft, comprising:
- a fuel tank;
- and
- a fuel tank access covering the fuel tank and including an outer fuel tank access cover, the outer fuel tank access cover including an inner surface and an outer surface,
- wherein the outer fuel tank access cover comprises an energy absorption area for absorbing the impact energy due to an object impacting against the outer fuel tank access cover.
An aircraft, comprising:
- a wing including a fuel tank and a fuel tank access covering the fuel tank, the fuel tank access including an outer fuel tank access cover, the outer fuel tank access cover including an inner surface and an outer surface,
- wherein the outer fuel tank access cover comprises at least one frangible line located on the inner surface of the outer fuel tank access cover that is calibrated for being ruptured once a predetermined level of energy due to an impact is reached.
