## Abstract

This special condition is issued for these Aerospatiale Model SA-365N, SA-365N1, and AS-365N2 ``Dauphin'' helicopters. These helicopters will have a novel or unusual design feature associated with the Electronic Flight Instrument System and with the digital standby system. The applicable airworthiness regulations do not contain adequate or appropriate safety standards for the protection of these critical function systems from the effects of external high intensity radiated fields (HIRF). This special condition contains additional safety standards that the Administrator considers necessary to establish a level of safety equivalent to that provided by the applicable airworthiness standards.
