Hartzell Continues to Advance the State of the Prop

By Dave Higdon

July 24, 2015 - Hartzell Propellers continues to advance the state of the prop as it's shown this week during EAA AirVenture 2015. With products suitable for everything from light-sport aircraft (LSA) to propjets, the Ohio-based company continues to reflect its long-standing reputation as a pioneering prop maker.

Among the advances Hartzell highlighted at AirVenture 2015 are:

Hartzell and Piper are now collaborating on STC approval for a 5-blade composite prop for the Piper Meridian and M500.

Hartzell's aluminum and composite Top Props are now available for various Mooney models.

Hartzell offers composite retrofit props for the Cirrus SR 22.

The company also won Type Certificate approval for its 2-blade Bantam prop for use on Rotax engines and entered into an agreement with Flight Design to supply a new two-blade swept prop for the planemaker's in-development alternative-fuel C4.

Hartzell also won Supplemental Type Certificate (STC) approval for its lightweight Scimitar prop on the Cessna 172RG Cutlass and signed a sole-source agreement with Quest Aircraft to supply its 4-blade aluminum propeller for the manufacturer's Kodiak propjet single.

Approval in China for King Air B200, Piaggio EVO and TBM series propellers.

China Type Certificate approved for Cessna TTx and Mooney Acclaim.

STC approved for Trailblazer composite propellers for Aviat Husky utility aircraft.

Agreement made with Piaggio Aero Industries to supply lightweight 5-blade props for Avanti EVO.

Hartzell Propeller Executive Vice President JJ Frigge also detailed advances in the company’s popular Trailblazer structural composite propeller, which the company designed specifically for back-country flying. Frigge noted that the Trailblazer delivers better take-off and climb performance along with rugged durability thanks to the use of aerospace-grade carbon fiber, a stainless steel shank, durable nickel cobalt leading edges and blades certified for unlimited life.
