What the agency says
These special conditions are issued for the Gulfstream Aerospace LP (Gulfstream) Model G300 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 the installation of a therapeutic oxygen distribution system that provides a shared source of oxygen between the flightcrew and passengers. 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.
