Airworthiness Directives; Airbus SAS Airplanes

FAA / Federal Register · 2021-18332

The FAA is adopting a new airworthiness directive (AD) for certain Airbus SAS Model A350-941 and -1041 airplanes. This AD was prompted by a report of in-production findings of missing or incorrect application of the lightning strike edge glow sealant protection at specific locations in the wing tanks. This AD requires an inspection for missing or incorrect application of the lightning strike edge glow sealant protection at certain locations in the wing tanks, and corrective action, as specified in a European Union Aviation Safety Agency (EASA) AD, which is incorporated by reference. The FAA is issuing this AD to address the unsafe condition on these products.
