## Abstract

These amended special conditions are issued to Avidyne Corporation, 55 Old Bedford Road, Lincoln, MA 01773. This is an amendment to special condition 23-184-SC, which was published on May 23, 2006 (71 FR 29574), for installation of an EFIS manufactured by Avidyne on various models. The original issue left off the Cirrus Design Corporation SR22, which was the first model to be certified under the STC. The airplanes listed under this multi-model approval 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 the Entegra II Avionics System, consisting of: (2) Model 700-0003-( ) Integrated Flight Displays (IFD), (2) Model 700- 00011-( ) Magnetometer/OAT sensors, and (1) Model 700-00085-000 Keyboard/Controller. These components are all manufactured by Avidyne Corporation, Inc. 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.
