An access cover for an aircraft hole that comprises a plurality of access cover holes, an inner surface, a plurality of first projections protruding from the inner surface, and a plurality of fixing elements configured to fix the access cover to a supporting structure of the aircraft hole. The fixing elements each comprise a male fixing element having an outer threaded surface, the male fixing element being configured to pass through a hole, and a locking element comprising a threaded hole and an extended portion, wherein the outer threaded surface of the male fixing element is configured to thread with the threaded hole of the locking element.

Access cover

Aircraft component with panels () stiffened with stringers () configured with a central section () and some feet () in which there are zones of potential intersections or interferences of said stringers () with spars () and ribs (), in which the configuration of the ends of the stringers () affected by said intersections or interferences includes a first section () in which the height of the central section () of the stringer () is reduced until it disappears and the width of the feet () is increased until it reaches a predetermined width A and a second section () with some extended feet () of said predetermined width A and no central section (), including in said first section () the mechanical means () for binding the end of the stringer () to the skin (). The invention also relates to a method for manufacturing said panels ().

Aircraft component with panels stiffened with stringers

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.
