Airplanes Federal Aviation Administration FAA, DOT.
ACTION: Notice of proposed rulemaking NPRM.
AGENCY:

The FAA proposes to adopt a new airworthiness directive AD for all Airbus SAS Model A330200, 300, 800, and 900 series airplanes; and Model A340200, 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.
DATES: The FAA must receive comments on this proposed AD by November 22, 2021.
ADDRESSES: You may send comments, using the procedures found in 14 CFR
11.43 and 11.45, by any of the following methods:
