The FAA's summary their words, unchanged

These special conditions are issued for the Safran Aircraft Engines (SAE), Silvercrest-2 SC-2D engine model. This engine model will have a novel or unusual design feature associated with an additional takeoff rating that maintains takeoff thrust in certain high ambient temperature conditions for a maximum accumulated usage of 20 minutes in any one flight. 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.
