Airworthiness Directives; Airbus SAS Airplanes

We propose to adopt a new airworthiness directive (AD) for all Airbus SAS Model A350-941 airplanes. This proposed AD was prompted by reports of an overheat failure mode of the hydraulic engine-driven pump (EDP), and a determination that the affected EDP needs to be replaced with an improved EDP. This proposed AD would require replacement of a certain EDP with an improved EDP. We are proposing this AD to address the unsafe condition on these products.
