Hartzell’s structural composite propeller technology is trusted by pilots around the world. It has been proven in years of service in the demanding commuter-regional airline industry on the Beech 1900C and 1900D, CASA 212, and Dornier Do328.

In 2006, Hartzell introduced the second generation Advance Structural Composite propeller blade (ASC-II). The Hartzell ASC-II is a propeller that delivers all of the advantages provided by Hartzell’s first generation of composite propellers – low weight, low inertia, and low life cycle costs – while minimizing the historical disadvantage: the high-cost manufacturing process.

The Hartzell ASC-II consists of a unique monocoque structure of advanced composite materials. The structure consists of carbon fiber laminates integrated into a co-molded stainless steel shank. The leading edge outboard of the de-ice boot is protected with a co-molded electroformed nickel erosion shield.

The latest design to be added to the growing family of structural composite propeller blades was recently certified on the Beechcraft King Air 250.
