Airworthiness Directives; Airbus SAS Airplanes

FAA / Federal Register · 2019-21241

The FAA is superseding Airworthiness Directive (AD) 2018-22- 13, which applied to certain Airbus SAS Model A350-941 and -1041 airplanes. AD 2018-22-13 required revising the existing airplane flight manual (AFM) to provide the flightcrew with updated procedures related to inboard aileron fault operations. This AD continues to require that AFM revision, and also requires modification of the electronic centralized aircraft monitoring (ECAM) procedures by installing an Airbus temporary quick change (ATQC) and activating an ECAM temporary change. This AD was prompted by a technical issue detected on the inboard aileron electrohydrostatic actuators that caused potential erroneous monitoring of those actuators. The FAA is issuing this AD to address the unsafe condition on these products.
