## 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 that during flight and fatigue testing it was detected that some fasteners installed in the center wing box (CWB) rotated inside their fastener holes. This proposed AD would require replacing affected fasteners and applying additional head nut cap protection at the front and rear spars in the CWB, as specified in a European Union Aviation Safety Agency (EASA) AD, which is proposed for incorporation by reference. The FAA is proposing this AD to address the unsafe condition on these products.
