Disposition of Comments

A notice of proposed policy was published in the Federal Register on February 3, 2004 (69 FR 5242). Two (2) commenters responded to the request for comments, and indicated their concurrence with the proposed policy.


Due to concerns about trapped waste material being a potential fire hazard, the FAA requested seat armrest cavities be either completely enclosed or have an open bottom. Subsequent FAA research determined that for typical armrest cavities, these conditions do not need to be met to prevent a fire hazard. The policy proposed on February 3, 2004, would change the earlier FAA position that armrest cavities be enclosed or open at the bottom.

The final policy as well as the disposition of comments received is available on the Internet at the following address:​rgl. If you do not have access to the Internet, you can obtain a copy of the policy be contacting the person listed under for further information contact.
