In an aircraft, many cavities are created by structural elements of the aircraft, such as door or window frames stiffeners These cavities are areas of unintentional storage condensation water generated by the differences in temperature and pressure during the flight of the aircraft. This water, in liquid or solid form add weight to the aircraft. Today, the solution is to install a drain that discharges the water to a nozzle of the general drainage system of the aircraft, leading to the outside of the aircraft. These drains are also a source of extra weight on the plane. The solution described here overcomes this problem. It consists of adding foam blocks within cavity to prevent from any water storage
