## Abstract

These special conditions are issued for the Embraer Model EMB- 135BJ (Legacy 650) airplanes, modified in accordance with design-change application (DCA) 0145-000-00020-2008/FAA (the most current FAA- approved revision; hereafter referred to as "the DCA"). This Model EMB-135BJ airplane, as modified by the DCA, is commonly referred to as the Legacy 650 airplane. It will have a novel or unusual design feature associated with engine size and the potential torque load imposed by sudden engine-stoppage conditions. 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.
