The FAA's summary their words, unchanged

These special conditions are issued for the Cessna Model 750 Series airplanes. These airplanes will have a novel or unusual design feature associated with the architecture and connectivity capabilities of the airplanes' computer systems and networks. Connectivity to, or access by, external systems and networks may result in security vulnerabilities to the airplanes' systems.
