Résumé

These special conditions are issued to Cessna Aircraft Co., for the Type Certificate of Model 510 Mustang airplane. This airplane 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 an Electronic Flight Instrumentation System (EFIS), Digital Air Data Computer (ADC), and a Full Authority Digital Engine Control (FADEC). The applicable regulations do not adequately consider failure of electrical and electronic systems performing critical functions from the effects of external 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 this airplane.
