The FAA has issued Final Special Conditions for Israel Aircraft Industries Model 1124 airplanes modified by Garrett Aviation Services. The FAA advises, “These modified 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 modification incorporates the installation of dual Innovative Solutions & Support (IS&S) Air Data Display Unit systems with the IS&S Air Data Sensor that 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.

Key Takeaways:
- The FAA has issued "Final Special Conditions" for Israel Aircraft Industries Model 1124 airplanes that have been modified.
- The modification involves the installation of novel and critical Innovative Solutions & Support (IS&S) Air Data Display Unit systems.
- These special conditions are necessary because current airworthiness regulations lack adequate safety standards to protect these new systems from High-Intensity Radiated Fields (HIRF), aiming to ensure an equivalent level of safety.
