Airworthiness Directive · Amendment 39-19709 · Flight controls
Airbus SAS Airplanes
This AD applies to all Airbus SAS Model A320-251N and A320-271N airplanes, certificated in any category.
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.
Except as specified in paragraph (h) of this AD: Comply with all required actions and compliance times specified in, and in accordance with, European Union Aviation Safety Agency (EASA) AD 2019-0189, dated July 31, 2019 (“EASA AD 2019-0189”).
(1) For purposes of determining compliance with the requirements of this AD: Where EASA AD 2019-0189 refers to its effective date, this AD requires using the effective date of this AD.
(2) The “Remarks” section of EASA AD 2019-0189 does not apply to this AD.
The aircraft, engines and makers this AD names, by the model designations in its text. A model listed here may still be outside the AD's serial ranges.
