Special Conditions; ARINC, Inc.; Raytheon Models 200, 300, and B300; Protection of Systems for High Intensity Radiated Fields (HIRF)

Resumo

These special conditions are issued to ARINC, Inc.; 1632 S. Murray Boulevard; Colorado Springs, CO 80916 for a Supplemental Type Certificate for the Raytheon Model King Air 200, 300 and B300 airplanes. These airplanes will have novel and unusual design features when compared to the state of technology envisaged in the applicable airworthiness standards. The novel and unusual design features include the installation of a Digital Air Data Computer on the copilot side. The Digital Air Data Computer will be either an IS&S ADDU (Air Data Display Unit) or a Thommen AD32 Air Data Display 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). These special conditions contain the additional safety standards that the Administrator considers necessary to establish a level of safety equivalent to the airworthiness standards applicable to these airplanes.
