Discover Hartzell’s new high-performance Polaris propeller, STC-approved for the Diamond DA-40 NG with the Austro Engine E4-A engine. The 74-inch diameter, three-blade advanced structural composite carbon fiber prop replaces the standard wood/composite propeller, featuring a lightweight Bantam aluminum hub and 2,400-hour/six-year TBO, with Hartzell’s warranty through the first overhaul.

A Difference for the Diamond DA-40:

  • High performance
  • Extremely lightweight
  • Low life-cycle costs

Additionally, the Polaris provides all-weather durability and reliability of a true carbon-fiber composite propeller system, which has been demonstrated and proven on multiple platforms.

The Polaris prop 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.” — JJ Frigge, Hartzell Propeller President
