Airworthiness Directives; Airbus Airplanes
Summary
We are adopting a new airworthiness directive (AD) for all Airbus Model A350-941 airplanes. This AD requires repetitive on-ground power cycles to reset the internal timer. This AD was prompted by the in-service loss of communication between some avionics systems and the avionics network. We are issuing this AD to address the unsafe condition on these products.
