An aircraft fuselage element includes an outer shell and an inner shell that is disposed with clearance relative to the outer shell. An intermediate space between the outer shell and the inner shell is connectable to an air source. A ventilation aperture that is formed in the aircraft fuselage element and connectable to the air source is provided with a semi-permeable membrane. The semi-permeable membrane is permeable to air flow in both directions and permeable to water in a flow direction into the intermediate space from outside the outer shell or the inner shell.
