Special Conditions: Bombardier Model BD-100-1A10 Airplanes; High-Intensity Radiated Fields (HIRF).

These special conditions are issued for Bombardier Model BD- 100-1A10 airplanes. These airplanes will have a novel or unusual design feature when compared to the state of technology envisioned in the airworthiness standards for transport category airplanes. The airplane design includes four large liquid crystal display (LCD) electronic displays, an integrated electronic standby system, and full authority digital engine controls (FADEC) all of which perform critical functions. The applicable airworthiness regulations do not contain adequate or appropriate safety 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 that established by the existing airworthiness standards.
