Airworthiness Directives; Airbus SAS Airplanes

FAA / Federal Register · 2019-17905

The FAA is adopting a new airworthiness directive (AD) for all Airbus SAS Model A320-251N and A320-271N airplanes. This AD was prompted by analysis and laboratory testing of the behavior of the flight control laws, which identified reduced efficiency of the angle of attack (AoA) protection that may result in excessive pitch attitude in certain configurations in combination with specific maneuvers commanded by the flight crew. This AD requires revising the existing airplane flight manual (AFM) to incorporate operational limitations, 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.
