Federal Aviation Administration (FAA), DOT.

( printed page 18912)

Final special conditions; request for comments.

These special conditions are issued for Boeing Model 747-400/-400D/ -400F series airplanes. These airplanes, as modified by Archeion Holdings LLC (Archeion), will have a novel or unusual design feature when compared to the state of technology envisioned in the airworthiness standards for transport-category airplanes. This design feature is a digital systems architecture that will allow increased connectivity to and access from external network sources, ( e.g., operator networks, wireless devices, internet connectivity, service provider satellite communications, electronic flight bags, etc.) to the airplane's previously isolated electronic assets (networks, systems, and databases). The applicable airworthiness regulations do not contain adequate or appropriate safety standards for this design feature. These special conditions contain the additional safety standards that the Administrator considers necessary to establish a level of safety equivalent to that established by the existing airworthiness standards.

This action is effective on May 5, 2025. Send comments on or before June 20, 2025.
