Special Conditions: Gulfstream Aerospace Corporation Model GVII-G500 Series Airplanes; Flight Envelope Protection-High Incidence Protection System.

This action proposes special conditions for the Gulfstream Aerospace Corporation (Gulfstream) Model GVII-G500 series airplanes. These airplanes will have a novel or unusual design feature when compared to the state of technology and design envisioned in the airworthiness standards for transport category airplanes. This design feature is a high incidence protection system that limits the angle of attack at which the airplane can be flown during normal low speed operation. 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.
