Special Conditions: Embraer S.A., Model ERJ 190-300 Series Airplanes; Electronic Flight Control System: Control Surface Position Awareness, Multiple Modes of Operation

These special conditions are issued for the Embraer S.A. Model ERJ 190-300 series 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. This design feature is a fly-by-wire electronic flight control system (EFCS) and no direct coupling from the flight deck controller to the control surface. As a result, the pilot is not aware of the actual control surface position. The applicable airworthiness regulations do not contain adequate or appropriate safety standards for this design feature. 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.
