With over 30 years of experience in the design and manufacturing of structural composite blades, Hartzell introduced the second generation Advance Structural Composite (ASC-II) blade in 2006. Several certified OEM airframe manufacturers have selected the ASC-II blade as standard equipment because of the low weight, low inertia, and low life cycle costs that it offers their customers.

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 outboard half of the leading edge is protected with a co-molded electroformed nickel erosion shield.

In the demanding aerobatic world Hartzell delivers this same durability, strength and weight savings with our composite aerobatic prop making it the prop of choice of some of the greatest aerobatic performers like Sean D. Tucker, Michael Goulian and Matt Chapman.

3-blade N7605 ASC-II composite blade currently certified to 350hp               3-blade aerobatic propeller with C7690 blades seen installed on Sean D. Tucker’s Oracle Challenger               N7605 ASC-II composite blade certified up to 350 hp
