## Abstract

On March 8, 2011, the FAA published an interim final rule, request for comments (Amendment Nos. 21-94, 25-133, 121-354, 129-50; SFAR 111) on security considerations for lavatory oxygen systems (77 FR 12550). The interim final rule addresses a security vulnerability and is needed so the affected airplanes can continue operating until the non- compliance to airworthiness standards and operating rules is resolved. We sought public comment on the interim final rule even though it became effective upon publication. This action responds to the public comments the FAA received.
