Airworthiness Directives; Airbus SAS Airplanes

The FAA is adopting a new airworthiness directive (AD) for certain Airbus SAS Model A350-941 and A350-1041 airplanes. This AD was prompted by a determination that in the event of rapid decompression at a specific location of the airplane, possible deflections of the passenger floor cross beams may result in wiring damages, leading to potential system losses. This AD requires amending the operator's existing airplane flight manual (AFM) to update the landing performance database, 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.
