## Abstract

These special conditions are issued for Dassault Falcon Fan Jet, Fan Jet Series D, Series E, Series F, Mystere-Falcon 20-C5, 20-D5, 20-E5, 20-F5, and Mystere-Falcon 200 airplanes modified by 3S Certification, LLC. These modified airplanes will have novel or unusual design features when compared with the state of technology envisioned in the airworthiness standards for transport category airplanes. The modification installs Thommen AD 30 Repeater Altimeters and a Skylight ADC 600 Air Data Converter Unit. The applicable airworthiness regulations do not contain adequate or appropriate safety standards for protecting these systems from 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 that established by the existing airworthiness standards.
