Airworthiness Directives; Airbus SAS Airplanes

FAA / Federal Register · 2021-05038

The FAA proposes to adopt a new airworthiness directive (AD) for certain Airbus SAS Model A350-941 and -1041 airplanes. This proposed 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 proposed AD would require 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 proposed for incorporation by reference. The FAA is proposing this AD to address the unsafe condition on these products.
