Special Conditions: Embraer Model ERJ 190 series airplanes; Sudden Engine \nStoppage, Interaction of Systems and Structures, Operation Without Normal \nElectrical Power, Electronic Flight Control Systems, Automatic Takeoff Thrust \nControl System (ATTCS), and Protection from Effects of High Intensity Radiated \nFields (HIRF).

These special conditions are issued for the Embraer Model ERJ 190 series airplane. This airplane will have novel or unusual design features when compared to the state of technology envisioned in the airworthiness standards for transport category airplanes. These design features are associated with (1) engine size and torque load which affect sudden engine stoppage, (2) electrical and electronic systems which perform critical functions, and (3) an Automatic Takeoff thrust Control Systems (ATTCS). These special conditions also pertain to the effects of such novel or unusual design features, such as their effects on the structural performance of the airplane. The applicable airworthiness regulations do not contain adequate or appropriate safety standards for these design features. 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.
