## Abstract

These special conditions are issued for the Raytheon Aircraft Company Model 390 airplane. This airplane will have a novel or unusual design feature(s) not typically associated with normal, utility, acrobatic, and commuter category airplanes. These design features include turbofan engines, engine location, swept wings and stabilizer, and certain performance characteristics necessary for this type of airplane. 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 existing in the current business jet fleet and expected by the user of this class of aircraft.
