Abstract: A fastener assembly for attaching a component or bracket to the inner surface of the skin of an aircraft wing is disclosed. The fastener assembly comprises a bolt having a shaft and a bolt retaining member that threadingly cooperates with the shaft to retain the bolt in a position in which it extends through a hole in the skin. The fastener also includes a component or bracket retaining member that also threadingly cooperates with a portion of the shaft protruding through said bolt retaining member to attach a component or bracket to said inner surface.

Abstract: A system for detecting misalignment of an aero surface relative to other aero surfaces during simultaneous deployment of the aero surfaces is disclosed. A generator configured to shine a laser through aligned apertures in a series of aero surfaces towards a reflector during deployment of the aero surfaces, a receptor to detect reflection of the laser from the reflector back through the apertures to the generator and, a controller operable to terminate further deployment of the aero surfaces in the event that no reflection is detected by the receptor, or if an actual time taken for the reflected beam of light to be detected by the receptor differs from a predetermined time.
