Special Conditions; Diamond DA 40; Protection of Systems for High Intensity Radiated Fields (HIRF)

These special conditions are issued to Diamond Aircraft Industries GmbH, N.A. Otto-Str. 5, A-2700 Wiener Neustadt, Austria, for a Type Certificate for the Model DA 40 airplane. This airplane will have the potential for novel and unusual design features when compared to the state of technology envisaged in the applicable airworthiness standards. The current design does not include novel and unusual design features such as the installation of electronic flight instrument system (EFIS) displays; however, Diamond Aircraft Industries GmbH would like to make the applicable tests necessary for these types of installations for which 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.
