Hartzell’s Swept Prop for TBM gets FAA OK

Hartzell Propeller has received type certificate approval from the FAA and European Aviation Safety Agency for an advanced swept airfoil structural composite five-blade propeller for TBM 700/850 aircraft.

The new design, specifically engineered for the single-engine TBM turboprop, delivers faster takeoff acceleration, higher cruise speeds and better climb, along with less noise, according to company officials.

“The stronger structural composite construction of these advanced carbon fiber blades and their sophisticated aerodynamic design boosts the TBM’s already-impressive performance to a higher level,” said Hartzell President Joe Brown. “We just finished flying cross country from Ohio to the Pacific Northwest in our TBM 700 with the new five-blade prop, and the added quickness and speed is striking, and its ramp presence is stunning.”

Mike McCorkle, corporate pilot for Hartzell, said, “Our TBM 700 with the new propeller will now climb comparable to our 850 model. Coming out of Coeur d’Alene, we went straight up to 27,000 feet in only 16 and a half minutes with temperature 8 degrees above standard. That’s an average of nearly 1,500 feet per minute, and we shaved at least a couple minutes off of our normal time to climb.”

With the new Hartzell propeller, the takeoff acceleration from zero to 90 knots is 10% faster than with any other available propeller, he noted.

Hartzell’s new propeller also provides for a 100-feet-per-minute faster climb rate. Cruise is 2 knots faster than the current four-blade prop, and 5 knots faster than the five-blade wood-based propeller option. The new Hartzell five-blade prop is also significantly quieter in the cabin and in the pattern.

Hartzell began taking orders for the new TBM five-blade prop at the TBM Owners and Pilots Association Convention held this past month in Coeur d’Alene, Idaho. The initial response to the new TBM propeller was very positive, Brown said, noting that a number of TBM owners at the convention placed advance orders for the new props for delivery following supplemental type certificate approval, which is expected in the first quarter of next year.

Hartzell offers the new prop with its “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-SOCATA’s distributor network.

    Could this 5-blade propeller be fitted on other aircraft like Cessna 208 EX, Quest KODIAK or Sherpa K650-T ?

    So how much does it cost, both to buy and to overhaul?
