Notice of proposed rulemaking (NPRM).
Summary
The Federal Aviation Administration (FAA) is proposing a new airworthiness directive that updates an earlier rule (AD 2023‑07‑02). The original directive required airlines to replace a “doghouse” door‑lock placard with a clearer instruction placard on certain Airbus A330 and A340 models. After further review, the FAA found that additional components also need to be modified to eliminate a safety risk, and it wants to bar the installation of those parts under specific conditions. In short, the rule aims to ensure that the cockpit door‑lock system works reliably and that crews have the correct information to operate it safely. The proposal applies to all Airbus SAS aircraft in the A330‑200, A330‑300, A330‑800, A330‑900, A340‑200, A340‑300, A340‑500, and A340‑600 series that are currently in service in the United States. It is issued by the Department of Transportation’s FAA, which oversees aircraft safety, and it affects airlines, maintenance providers, and any operators of the listed models. The notice was published on September 9, 2026, in the Federal Register (91 FR 57281). Comments on the proposal must be submitted by October 26, 2026. After the comment period, the FAA will review the feedback, possibly revise the directive, and then issue a final rule that would become mandatory for the affected aircraft.

Official abstract
The FAA proposes to supersede Airworthiness Directive (AD) 2023-07-02, which applies to all Airbus SAS Model A330-200, -300, -800, and -900 series airplanes; and Model A340-200, -300, -500, and -600 series airplanes. AD 2023-07-02 requires replacing the doghouse door lock placard with an improved instruction placard. Since the FAA issued AD 2023-07-02, it was determined that additional parts need to be modified. This proposed AD would continue to require the actions in AD 2023-07-02 and would expand the list of affected parts. 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.
