Apparatus, method for draining fluid, and method of fabricating a drainage apparatus for drainage of fluid through an exterior of an aircraft are disclosed. The apparatus includes a drain element having an aft end portion and an annular connector, wherein the annular connector is to be disposed within a drain port in an exterior panel of the aircraft. The drain element includes a forward end portion with a contoured protrusion disposed over the annular connector, and a drain opening at the aft end of the contoured protrusion. The contoured protrusion enables fluid to flow from the drain port through the annular connector and out the drain opening. An airflow across the contoured protrusion creates a reduced pressure region external to the drain opening relative to the pressure at the annular connector and drain port, so as to induce fluid flow through the annular connector in the drain port and out the drain opening.
