Hartzell Propeller Receives STC for Diamond DA40 NG Prop with Austro Engine E4-A

Hartzell Propeller receives a supplemental type certificate (STC) from the FAA to replace Diamond DA40 NG MT wood/composite propellers with new 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 2,4000-hour/six-year TBO, with Hartzell's warranty through first overhaul.

"Hartzell's Top Prop performance conversion kit includes the propeller, a white or metallic silver composite spinner, and STC documentation," says Hartzell Propeller president, JJ 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 adds.

The kit for the advanced, blended airfoil design prop sells for $24,613. The STC is limited to 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.
