## Summary

The FAA proposes to adopt a new airworthiness directive (AD) for all Airbus SAS Model A350-941 and -1041 airplanes. This proposed AD was prompted by a report that sticking effects have been observed affecting the breathing bag on certain passenger oxygen masks. This proposed AD would require replacement of affected passenger oxygen masks, as specified in a European Union Aviation Safety Agency (EASA) AD, which will be incorporated by reference. The FAA is proposing this AD to address the unsafe condition on these products.
