Abstract
The FAA is adopting a new airworthiness directive (AD) for certain Airbus SAS Model A350-941 airplanes. This AD was prompted by reports of improperly locked diagonal struts located in a certain section of the fuselage; the teeth of the lock washers were incorrectly engaged, which could lead to a loss of tightening torque of an affected strut. This AD requires inspecting the diagonal strut for correct installation and for correct locking of the lock washers, and corrective actions if necessary, as specified in a European Union Aviation Safety Agency (EASA) AD, which is incorporated by reference. The FAA is issuing this AD to address the unsafe condition on these products.
