Final rule; request for comments.
Summary
The FAA is adopting a new airworthiness directive (AD) for certain Airbus SAS Model A350-1041 airplanes. This AD was prompted by a report of a computer software error leading to the rudder oscillatory failure case not being calculated properly. This AD requires updating certain computer software, 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.
