The FAA's summary their words, unchanged
These special conditions are issued for the Hartzell Propeller, Inc., Model HD-E6C-3( )/E13482K Dual Acting Propeller installed on Dornier DO-328 aircraft. This propeller uses a dual acting pitch control system and has propeller blades constructed using composite material. These design features are novel and unusual. Part 35 of the Federal Aviation Regulations (FAR) does not currently address the airworthiness considerations associated with dual acting, pitch control systems, or propellers constructed using composite blades. These special conditions contain the additional safety standards which the Administrator considers necessary to establish a level of safety equivalent to that established by the airworthiness standards of part 35 of the FAR.
