Hartzell Frontier propeller STC-approved for Continental-powered Cessna Skywagons

The kit includes a polished spinner and all documentation for the FAA-approved STC, according to Hartzell.

Hartzell Propeller has secured supplemental type certificate (STC) approval on its new Frontier scimitar aluminum propeller for Cessna 180 Skywagon airplanes equipped with Continental O-470 engines.

Targeted to serve Skywagon models A-J, the 88-inch prop, in an all-aluminum design, features two distinctive scimitar blades plus an aluminum hub.

Hartzell said the Frontier preserves the classic style of the tailwheel Skywagon, maintaining its superior prop clearance profile, even considering the extended blade length.

“The Skywagon community has been looking for a way to get more performance from these trusted aircraft without the downtime and expense of an engine upgrade,” said JJ Frigge, president of Hartzell Propeller.

Featuring Hartzell’s Top Prop Warranty – claimed to be the longest warranty programme in general aviation – through the first overhaul, the propeller offers up to 5% in performance improvements on ground roll, total takeoff distance and climb.

 “The Frontier is our answer – an affordable, two-blade aluminum Hartzell propeller designed to help pilots get off the ground faster, climb out of tight strips better and give the Skywagon a presence you can hear as well as feel,” added Frigge.  “It is an especially compelling solution for floatplane operators and pilots flying in demanding environments, such as Alaska.”

The kit includes a polished spinner and all documentation for the FAA-approved STC. The installed propeller assembly weighs 55.4lbs (25.1kg), and the Frontier works with O-470 A, J, K, L, R and S engine models. The upgrade comes with no RPM restrictions, which means no yellow caution range to avoid on climb, descent or in cruise.
