This proposed AD would require inspecting each T/R hinge for the presence of a nut and washer, installing a new nut and washer if necessary, and applying a torque stripe at each T/R hinge location, as specified in a European Union Aviation Safety Agency (EASA) AD, which will be incorporated by reference. The FAA is proposing this AD to address the unsafe condition on these products.
