Charleston, S.C., Oct. 7, 2015 – Hartzell Propeller has delivered more than 150 advanced swept airfoil five-blade props for Daher TBM 700/850/900 aircraft in the 18 months since receiving FAA type certificate approval for the high performance props. The announcement was made today at the 15th Annual TBM Owners and Pilots Association Convention held in Charleston Oct. 7-11.

“Hartzell’s new high performance structural composite propellers are flying on more than 20 percent of the entire Daher TBM fleet after less than two years on the market,” said Hartzell Propeller President Joe Brown. “That is a true testament to its performance with shorter takeoff rolls, faster climb, quieter cabins, smoother rides and shorter stopping distances. And it looks sweet on the ramp.”

The Hartzell prop available for retrofit on the 700/850 fleet comes as standard equipment on new DAHER TBM 900 aircraft. Hartzell Propeller expects deliveries for new TBM 900s and retrofits to exceed a total of 200 during the first quarter of 2016, Brown added. Hartzell has received approval for retrofitting TBM model 700 and 850 aircraft from the FAA, EASA and China.

Hartzell offers the new prop with a Plus 3 warranty, which covers the propeller for a full three years or 1,000 hours and a 3,600-hour/six-year TBO (Time Between Overhaul). The new propeller is available directly through Hartzell’s Top Prop conversion program ( or through DAHER’s distributor network.

Composite Advantages
Carbon composite, due to its incredible strength and light weight, allowed Hartzell to optimize blade chord thickness and sweep while achieving maximum strength. The strong structural composite construction of the carbon fiber blades and their sleek aerodynamic design boosts the TBM’s already impressive performance.

With the new Hartzell propeller, TBM 700/850 takeoff acceleration, from zero to 90 knots, is 10 percent faster than with any other available propeller. Hartzell’s advanced propeller also provides for hundreds of feet-per-minute faster climb. Cruise is two or more knots faster than the Hartzell four-blade metal prop and a full five knots faster than a five-blade wood-based propeller. The new Hartzell five-blade prop is also significantly quieter in the cabin and in the pattern.
