Summary
Final rule.
The FAA is adopting a new airworthiness directive (AD) for certain Airbus SAS Model A330-941 airplanes.

This AD requires the installation of a new FCPC standard and applicable concurrent modifications. This AD also prohibits the installation of certain parts. The FAA is issuing this AD to address the unsafe condition on these products.
