Abstract
An aircraft manhole including a skin panel of an aircraft structure, wherein an outer door and an inner door of the aircraft manhole are positioned on the skin panel. The aircraft manhole further includes stringers installed on the skin panel positioned on and attached to the skin, and fixing edges partially projecting through the manhole on the side for positioning the outer door and the inner door. The aircraft manhole also includes reinforcements arranged between the outer door and the inner door of the manhole that are attached to the skin, the reinforcements forming the fixing edges on one of its sides, and a cavity arranged in the skin to allow installing the outer door, thus maintaining the aerodynamic surface of the assembly as well as its tightness.
