Special Conditions: Gulfstream Model GVII-G500 Airplanes, Automatic Speed Protection for Design Dive Speed

These special conditions are issued for the Gulfstream Model GVII-G500 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 associated with a reduced margin between design cruising speed, V<INF>C</INF>/M<INF>C</INF>, and design diving speed, V<INF>D</INF>/M<INF>D</INF>, based on the incorporation of a high-speed protection system that limits nose-down pilot authority at speeds above V<INF>C</INF>/M<INF>C</INF>. 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.
