Airworthiness Directives; Airbus SAS Airplanes

摘要

The FAA is adopting a new airworthiness directive (AD) for all Airbus SAS Model A321-251N, A321-252N, A321-253N, A321-271N, A321-272N, A321-251NX, A321-252NX, A321-253NX, A321-271NX, and A321-272NX airplanes. This AD was prompted by analysis of the behavior of the elevator aileron computer (ELAC) L102 that revealed that excessive pitch attitude can occur in certain conditions and during specific maneuvers. This AD requires revising the airplane flight manual (AFM) to incorporate updated procedures and 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.
