The FAA's summary their words, unchanged

We are issuing these special conditions for the Turbomeca Ardiden 3K model engines. This engine model will have a novel or unusual design feature that is a 30-minute all engines operating (AEO) power rating for hovering at increased power (HIP). This rating is primarily intended for high-power hovering operations that are normal mission functions. 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 FAA considers necessary to establish a level of safety equivalent to that established by the existing airworthiness standards.
