Airworthiness Directives; Airbus SAS Airplanes

The FAA is adopting a new airworthiness directive (AD) for certain Airbus SAS Model A330-941 airplanes. This AD was prompted by an occurrence of a triple "PRIM FAULT" in the Flight Control Primary Computer (FCPC) at touchdown. This AD requires the installation of a new FCPC standard and applicable concurrent modifications. This AD also prohibits the installation of certain parts. The FAA is issuing this AD to address the unsafe condition on these products.
