Final rule; request for comments.
Summary
We are adopting a new airworthiness directive (AD) for certain Airbus SAS Model A350-941 and -1041 airplanes. This AD was prompted by a report that due to an issue with the flight warning system (FWS) logic, it is possible that the "AIR Auxiliary Power Unit (APU) BLEED LEAK" electronic centralized aircraft monitoring (ECAM) alert can trigger several times. This AD requires revising the airplane flight manual (AFM) to incorporate procedures related to an APU bleed leak. We are issuing this AD to address the unsafe condition on these products.
