Special Conditions: Textron Aviation, Inc. Model 560XL(XLS+) Airplane; Electronic System Security Protection From Unauthorized Internal Access

These special conditions are issued for the Textron Aviation, Inc. (Textron) Model 560XL(XLS+) airplane. This airplane 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 associated with the installation of a digital system that contains a wireless and hardwired network with hosted application functionality that allows access, from a source internal to the airplane, to the airplane's internal electronic component. 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.
