Hartzell Aviation, a consortium of companies, calls Hartzell Propeller its flagship, and for good reason. The propeller OEM based in Piqua, Ohio, has pushed forward with its blended airfoil props, with many utilizing composite construction to achieve the advanced designs. And the aftermarket Top Prop program through which Hartzell has delivered those props to a wide range of airframe and engine combinations has proven popular with pilots and owners.
At EAA AirVenture in Oshkosh, Hartzell announced it will deliver its 30,000th replacement prop in the conversion program in 2023. The Top Prop catalog boasts more than 100 options, aggregated over the course of 30 years, including from OEMs like Beechcraft, Cessna, Diamond, Piper, Mooney, Pilatus, Daher, and others.
