Final rule.

We are adopting a new airworthiness directive (AD) for certain Airbus SAS Model A350-941 airplanes. This AD was prompted by a determination that certain holes for the vertical tail plane (VTP) tension bolts connection are not properly protected against corrosion. This AD requires modifying the VTP tension bolts connection by adding sealant and protective treatment to the head of the connection, at the barrel nut cavities, and in the surrounding area. We are issuing this AD to address the unsafe condition on these products.
