## Summary

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 reports of sealant bead damage caused by rotation of the attachment fitting bearing assembly of a trimmable horizontal stabilizer (THS). This proposed AD would require repetitive detailed inspections (DET), and applicable corrective action(s) if necessary, as specified in a European Union Aviation Safety Agency (EASA) AD, which will be incorporated by reference. In addition, as specified in the EASA AD, this proposed AD would provide an optional modification that would terminate the inspections. The FAA is proposing this AD to address the unsafe condition on these products.
