## Summary

The FAA proposes to adopt a new airworthiness directive (AD) for certain Airbus SAS Model A350-941 and -1041 airplanes. This proposed AD was prompted by a report indicating that when the number 2 engine thrust reverser (T/R) was opened, the right-hand T/R hinge nut located at position

((Page 21116))

4 was found detached; investigation revealed that certain nuts could have been installed with noncompliant locking features, or with locking features that could degrade quicker than anticipated. 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.
