Summary
We propose to supersede Airworthiness Directive (AD) 2018-22- 13, which applies to certain Airbus SAS Model A350-941 and -1041 airplanes. AD 2018-22-13 requires revising the airplane flight manual (AFM) to provide the flightcrew with updated procedures related to inboard aileron fault operations. Since we issued AD 2018-22-13, we have determined that additional actions are necessary to address the unsafe condition and that additional airplanes are subject to the unsafe condition. This proposed AD would also require modifying the electronic centralized aircraft monitoring (ECAM) procedures by installing an Airbus Temporary Quick Change (ATQC) and activating an ECAM temporary change (ETC). We are proposing this AD to address the unsafe condition on these products.
