The FAA's summary their words, unchanged
These special conditions are issued for the Hamilton Sundstrand model NP2000 constant speed propeller. This eight-bladed propeller uses a dual acting digital electro-hydraulic propeller control system and has blades constructed of composite materials. These design features are novel and unusual. 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.
