The higher performance 3-bladed Polaris propeller is to be a factory option on new DA40 NGs
Hartzell Propeller’s 3-blade carbon fiber Polaris prop is now offered as a factory option on new Diamond DA40 NG four-seaters.
Working closely with Diamond Aircraft, Hartzell Propeller has also 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.
The announcement was made by Hartzell Propeller President JJ Frigge, at EAA Air Venture. Oshkosh 2023.
“Hartzell's Top Prop performance conversion kit includes the propeller, a white or metallic silver composite spinner, and STC documentation," said Frigge. "It delivers light, smooth and state-of-the-art improved climb performance, two to three KTAS faster cruise and is more durable, with an eco-friendly 74.1 dB(a) noise level," he added.
The Top Prop conversion kit is for DA40 NGs equipped with MÄM 40-434 (Cowling Redesign) or OÄM 40-310 (Exhaust System with Muffler).
Hartzell's three-blade advanced structural composite propeller for the Diamond delivers low weight, low inertia, and low life cycle costs. Additionally, it provides all-weather durability and reliability of a true carbon-fiber composite propeller system, which has been demonstrated and proven on multiple platforms.
