## Abstract

These special conditions are issued for the Embraer S.A. Model EMB-505 airplane. The EMB 505 is an all-new, high-performance, sweep wing, twin turbofan powered aircraft. This airplane will have a novel or unusual design feature(s) which include turbofan engines, aft engine location, new avionics, a trimmable horizontal tail, and performance characteristics inherent in this type of airplane that were not envisioned by the existing regulations. In addition, this airplane is a jet airplane being certificated in the commuter category by exemption. 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.
