Summary
We are adopting a new airworthiness directive (AD) for all Airbus SAS Model A350-941 and -1041 airplanes. This AD was prompted by reports that electro-hydrostatic actuators (EHAs), installed on the inboard ailerons, elevators, and rudder, had degraded insulation resistance in the direct drive solenoid valve (DDSOV), due to incorrect sealing application. This AD requires a check of the insulation resistance of the DDSOV of each affected EHA and applicable corrective actions. We are issuing this AD to address the unsafe condition on these products.
