## Summary

The FAA proposes to adopt a new airworthiness directive (AD) for all Airbus SAS Model A330-941 airplanes. This proposed AD was prompted by reports indicating premature aging of certain chemical oxygen generators. This proposed AD would require repetitively removing the affected chemical oxygen generators and replacing them with serviceable parts, 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.
