## Summary

The FAA proposes to adopt a new airworthiness directive (AD) for certain Airbus SAS Model 330-200, A330-200 Freighter, and A330-300 series airplanes. This proposed AD was prompted by a report of contamination of the advanced pneumatic detector pressure switch of engine pylon fire detectors. This proposed AD would require replacement of the affected parts and would prohibit installation of affected parts, as specified in a European Union Aviation Safety Agency (EASA) AD, which is proposed for incorporation by reference (IBR). The FAA is proposing this AD to address the unsafe condition on these products.
