Special Conditions: Mitsubishi Aircraft Corporation Model MRJ-200 Airplane; Use of Automatic Power Reserve for Go-Around Performance Credit

These special conditions are issued for the Mitsubishi Aircraft Corporation (MITAC) Model MRJ-200 airplane. This airplane 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 an Automatic Takeoff Thrust Control System (ATTCS), referred to as an Automatic Power Reserve (APR), to set the performance level for approach-climb operation after an engine failure. 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.
