Learjet transport category airplane; electronic system security protection; Aerospace electric equipment and systems (ICS 49.060), On-board equipment and instruments (ICS 49.090)

Special Conditions: Learjet, Inc.; Electronic System Security Protection From Unauthorized External Access (2 page(s), in English)

Final special conditions; request for comments - These special conditions are issued for a supplemental type certificate on certain transport category airplanes. These airplanes, as modified by Learjet, Inc. (Learjet), 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 the installation of a system that allows connection to airplane electronics and networks, and access from aircraft external sources (e.g., operator networks, wireless devices, internet connectivity, service provider satellite communications, electronic flight bags, etc.) to the previously isolated airplane 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.
