Special Conditions: Turbomeca Arriel 2D Turboshaft Engine
These special conditions are issued for Turbomeca SA model Arriel 2D engines. The engine model will have a novel or unusual design feature which is a 30-minute power rating. This rating is generally intended to be used for hovering at increased power for search and rescue missions. The applicable airworthiness regulations do not contain adequate or appropriate safety standards for this design feature. These special conditions contain the added safety standards that the Administrator considers necessary to establish a level of safety equivalent to that established by the existing airworthiness standards.
