Abstract
An aircraft structural element having a cavity. The structural element has an opening in a wall of the cavity through which moisture located in the cavity can escape into the surroundings, wherein a drainage element for sealing the opening in the wall of the cavity is provided in the opening. In order that the structural element can be produced with a low expenditure on components and assembly equipment, the drainage element comprises a hollow cylinder which connects the cavity of the structural element to the surroundings, which is provided with an external thread having a predefined external diameter, and a head at one end which has a predefined diameter, wherein the external diameter of the thread is smaller than the head diameter.

An aircraft structural element having a cavity with a wall, the wall including an opening through which moisture located in the cavity can escape into the surroundings external to the aircraft, and a drainage element configured to seal the opening, the drainage element comprising:
- a hollow cylinder that connects the cavity of the structural element to the surroundings;
- the hollow cylinder having an external thread having a predefined external diameter, a head at one end of the hollow cylinder that has a predefined head diameter, wherein the predefined external diameter of the external thread is smaller than the predefined head diameter;
- wherein the head diameter is greater than a diameter of the opening and the external thread diameter of the hollow cylinder has a diameter less than the diameter of the opening to allow the drainage element to be inserted into the opening, wherein the head is retained in an interior of the cavity and the hollow cylinder extends through the opening, the hollow cylinder having a passage connecting the cavity of the structural element to the surroundings.
