The FAA has issued a supplemental type certificate (STC) to Hartzell Propeller for its new Frontier aluminum propeller for the Cessna 180 Skywagon powered by Continental O-470 engines. The STC for the two-blade propeller covers Skywagon A-J models.

Featuring an 88-inch diameter, the propeller’s blades feature a scimitar design and an aluminum hub. With the new Frontier Top Prop installed, Skywagon owners will realize up to a 5% improvement in ground roll, total takeoff distance, and climb performance.
