Hartzell Propeller

Working closely with Diamond Aircraft, Hartzell Propeller has received a Supplemental Type Certificate (STC) from the FAA to replace Diamond DA40 NG MT wood/composite propellers with new and higher performance 3-bladed lightweight Polaris composite props. The 74-inch diameter three-blade ASCII carbon fiber prop for the Austro Engine E4-A features a lightweight Bantam aluminum hub and 2,400-hour / six-year TBO, with Hartzell's warranty through first overhaul.
