## Summary

The FAA proposes to adopt a new airworthiness directive (AD) for all Airbus SAS Model A330-200, -300, -800, and -900 series airplanes; and Model A340-200, -300, -500, and -600 series airplanes. This proposed AD was prompted by reports that the instructions on the doghouse door lock placard are unclear and incomplete. This proposed AD would require replacing the placard with an improved instruction placard, as specified in a European Union Aviation Safety Agency (EASA) AD, which is proposed for incorporation by reference. This proposed AD would also prohibit the installation of affected parts under certain conditions. The FAA is proposing this AD to address the unsafe condition on these products.
