OSHKOSH, Wisconsin—The FAA has granted a supplemental type certificate (STC) to Wipaire for its Yukon propeller. The four-bladed prop, designed by both Wipaire and Hartzell, is on display here this week at the Wipaire booth at EAA AirVenture.
The Yukon features carbon composite construction and a nickel leading edge. It can be used on both the wheeled and floated Cessna Caravan utilizing the PT6A-114A 675 SHP or PT6A-140 867 SHP engines.
According to Wipaire, the Yukon can reduce takeoff distances by up to 26 percent from land and 31 percent on water. The propeller weighs 137 pounds, which is lighter than others available by about 19 pounds. It also has optional pitch locks, and according to the company, will not change the stall speed of the aircraft.
The Yukon is available with TKS or electric deice, or both.
“The successful flight performance with the Yukon is a testament to the collaboration between Hartzell Propeller and Wipaire engineers,” said Chuck Wiplinger, president and CEO of Wipaire. "The increased efficiency and power are a game changer for our customers and presale deposits are strong."
