Abstract

An aircraft door drainage system includes a precipitation receptacle disposed longitudinally along an upper edge of an aircraft door opening. The receptacle is mounted along the upper edge of the door opening by a plurality of brackets that connect the receptacle to an inside ceiling panel of the aircraft. The receptacle protrudes outward from the upper edge of the door opening into a path followed by precipitation falling off of an outer peripheral surface of a fuselage of the aircraft from locations above, forward, and aft of the door opening into the door opening when the aircraft door is in an open position. The receptacle remains clear of the aircraft door when the aircraft door is closed into the door opening. Drain hoses are connected at first and second ends of the receptacle to direct precipitation collected in the receptacle to an outside of the aircraft.
