Special Conditions: Airbus A300 Model B2-1A, B2-1C, B4-2C, B2K-3C, B4-103, B2-203, B4-203 Airplanes; High Intensity Radiated Fields (HIRF)

These special conditions are issued for Airbus A300 Model B2- 1A, B2-1C, B4-2C, B2K-3C, B4-103, B2-203, B4-203 airplanes modified by Electronic Cable Specialists. These airplanes will have novel and unusual design features when compared to the state of technology envisioned in the airworthiness standards for transport category airplanes. The installation of Honeywell Classic Navigator Systems will use advanced electronics when compared to the Inertial Navigation Systems. The applicable type certification regulations do not contain adequate or appropriate safety standards for the protection of this system 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 provided by the existing airworthiness standards.
