Installation and Operation of Flightdeck Installed Physical Secondary Barriers on Transport Category Airplanes in Part 121 Service - Notice of Proposed Rulemaking (NPRM)

The FAA has proposed requiring a second barrier to the flight deck on certain commercial airplanes. The additional barrier would protect flight decks from intrusion when the flight deck door is open. The public has 60 days to comment on the proposed rule once it is published in the Federal Register. The FAA will publish a final rule after the comment period closes.

The FAA Aircraft Certification Service Deputy Executive Director signed this notice of proposed rulemaking on July 27, 2022. Please be advised that the published document may contain minor changes due to formatting and editorial requirements, and the docket will not go live until publication. Upon publication, the document may be found on the Federal Register’s website at www.federalregister.gov and parties may submit comments in the docket at www.regulations.gov.
