Hartzell Propeller has joined forces with Diamond Aircraft to introduce an innovative upgrade for the Diamond DA40 NG four-seaters. This collaboration has resulted in a Supplemental Type Certificate (STC) from the FAA, paving the way for the replacement of existing Diamond DA40 NG MT wood/composite propellers with cutting-edge 3-bladed lightweight Polaris composite props.
These 74-inch diameter, three-blade ASCII carbon fiber props are designed to enhance performance and are tailored for the Austro Engine E4-A. They feature a lightweight Bantam aluminum hub and boast an impressive 2,400-hour / six-year TBO, all backed by Hartzell's renowned warranty coverage through the first overhaul.
- Speed Boost: You'll notice a significant increase of 2 to 3 knots true airspeed (KTAS), making your journeys faster and more efficient with only a slight increase in take off roll performance for the high-end speed profile.
- Diameter: This propeller boasts an impressive 74 inches in diameter, ensuring optimal performance for your DA40 NG.
- Lightweight Design: Featuring a "Bantam" aluminum hub and carbon fiber blades, the POLARIS propeller weighs in at just 33.1 pounds (Prop & Spinner). That's a significant weight reduction compared to its predecessor, the MTV-6-R/190-69 3-blade wood/composite propeller, which weighed 35.0 pounds (Prop & Spinner).
Hartzell's Top Prop conversion kit includes not only the propeller itself but also a choice of a white or metallic silver composite spinner, along with comprehensive STC documentation. This upgrade delivers a host of benefits, including smoother operation, state-of-the-art climb performance improvements, and a cruise speed increase of two to three knots true airspeed (KTAS). Moreover, it's engineered for durability and environmental friendliness, with a noise level of just 74.1 dB.
This remarkable Top Prop conversion kit is available for DA40 NGs equipped with either MÄM 40-434 (Cowling Redesign) or OÄM 40-310 (Exhaust System with Muffler).
