Airworthiness Directives; Airbus SAS Airplanes

The FAA proposes to adopt a new airworthiness directive (AD) for all Airbus SAS Model A330-841 and A330-941 airplanes. This proposed AD was prompted by a report of cracks on the discharge outlet of certain engine fire extinguisher bottles. This proposed AD would require modification of affected fire extinguisher bottles, and would also prohibit the installation of affected parts. The FAA is proposing this AD to address the unsafe condition on these products.
