## Summary

We propose to adopt a new airworthiness directive (AD) for certain Airbus SAS Model A350-941 airplanes. This proposed 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 proposed AD would require 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 proposing this AD to address the unsafe condition on these products.
