## Abstract

This special condition is issued for the Agusta Model A109D and A109E helicopters. These helicopters will have a novel or unusual design feature associated with electronic systems that perform critical functions. The applicable airworthiness regulations do not contain adequate or appropriate safety standards for the protection of the electronic systems that perform critical functions from the effects of external high intensity radiated fields (HIRF). This special condition contains the additional safety standards that the Administrator considers necessary to establish a level of safety equivalent to that established by the applicable airworthiness standards.
