OSHKOSH, Wis., July 22, 2024 – Wipaire has received STC approval from the Federal Aviation Administration for Hartzell Propeller’s Yukon four-blade props with improved low-speed thrust, providing better takeoff and climb performance in Cessna Caravans.
The announcement was made today at EAA AirVenture Oshkosh, which runs from July 22 to July 28. Wipaire’s modified Cessna Caravan with Hartzell’s 4-blade Yukon prop will be on static display at the Wipaire’s Booth (#162).
Hartzell worked with Wipaire, a leading aircraft engineering and manufacturing company, to achieve FAA approval. The newly designed composite 110-inch diameter props are available with or without TKS ice protection or electric de-ice boots.
Wipaire flight test results showed there is up to a 26 percent decrease in total takeoff distance from land and up to a 31 percent decrease in takeoff from water on the Caravan with a Yukon prop. The improved performance can provide safer takeoffs and landings on smaller lakes and shorter runways.
Another important improvement is in weight savings. Coming in at 137 pounds, the Yukon is up to 19 pounds lighter than other available props.
The impressive flight performance with the Yukon is a credit to engineers from both Hartzell and Wipaire, as well as Wipaire test pilots. Wipaire’s test results also confirmed that there is no change in Caravan stall speeds.
The Yukon is available with pitch locks. Additionally, the Yukon’s carbon composite construction and nickel leading edges reduce risks for corrosion.
The new Wipaire Yukon STC applies to:
· C208 & C208B floated or wheeled
· PT6A-114A 675 SHP Engine (S/N 208B5000 and up)
· PT6A-140 867 SHP Engine (S/N 208B5000 and up) |
