## Summary

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 reports of corrosion on lavatory floor fittings at various locations. This proposed AD would require repetitive inspections of the affected lavatory floor fittings and applicable corrective actions and would allow replacement of each affected floor fitting as an optional terminating action. This proposed AD would also limit the installation of affected parts under certain conditions for certain airplanes and would prohibit the installation of an affected lavatory for certain airplanes. The FAA is proposing this AD to address the unsafe condition on these products.
