These special conditions are issued to Envoy Aerospace, 5027 Switch Grass Lane, Naperville, Illinois 60564-5368, for a Supplemental Type Certificate for the Raytheon B200, B200C, 300, B300, and B300C models. These models will have novel and unusual design features when compared to the state of technology envisaged in the applicable airworthiness standards. These novel and unusual design features include the installation of an electronic flight instrument system (EFIS) and a navigation display. The EFIS consists of the Universal Avionics, Inc. EFI-890R system for which the applicable regulations do not contain adequate or appropriate airworthiness standards for the protection of these systems from the effects of high intensity radiated fields (HIRF). The installation includes three EFI-890R Flat Panel Displays (two Primary Flight Displays Pilot/Copilot and one Navigational Display), and supporting equipment. These special conditions contain the additional safety standards thatthe Administrator considers necessary to establish a level of safety equivalent to the airworthiness standards applicable to these airplanes.
