Airworthiness Directives; Airbus SAS Airplanes

The FAA is adopting a new airworthiness directive (AD) for all Airbus SAS Model A350-941 and -1041 airplanes. This AD was prompted by a design review that identified a potential thrust asymmetry condition during derated takeoff operations under certain conditions. This AD requires revising the existing airplane flight manual (AFM) to provide the flightcrew with procedures for derated takeoff limitations. The FAA is issuing this AD to address the unsafe condition on these products.
