Special Conditions: Gulfstream Model GVI Airplane; Limit Engine Torque Loads for Sudden Engine Stoppage

These special conditions are for the Gulfstream GVI airplane. This airplane has novel or unusual design features when compared to the state of technology envisioned in the airworthiness standards for transport category airplanes. These design features include engine size and the potential torque load imposed by sudden engine stoppage. These special conditions pertain to their effects on the structural performance of the airplane. The applicable airworthiness regulations do not contain adequate or appropriate safety standards for these design features. 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.
