A method of determining how to repair a damaged composite component includes generating a three-dimensional model of the damaged component, determining a configuration of a repair structure to be applied to the damaged component using the generated three-dimensional model and general design data for the component prior to being damaged, determining an operational feasibility of the determined repair structure using application specific information related to the damaged component and generating a repair procedure for forming the repair structure when the determined operational feasibility indicates that the damaged component can be successfully repaired.

A composite bonded repair method for an aircraft is provided. The method includes generating a doubling patch of a portion of the aircraft from topographic data, filling damage at the portion of the aircraft with filler material, applying adhesive to the portion of the aircraft and the filler material and adhering the doubling patch to the adhesive.

An access door assembly includes a door panel located at a door opening and a primary hinge having a primary hinge axis and operably connected to the door panel. A guide track is affixed at the door opening and is operably connected to the door panel to guide rotation of the door panel about the first hinge axis. A secondary hinge having a secondary hinge axis is operably connected to the door panel. The secondary hinge allows for rotation of a first portion of the door panel about the secondary hinge axis, while a second portion of the door panel is stationary.
