Three-Bladed Prop Boosts Takeoff, Climb, Cruise

Hartzell has received FAA approval for a Supplemental Type Certificate (STC) that covers new 3-bladed propellers installed on Cessna's pressurized P210N (1978-84) and turbocharged T210F-N (1966-84) models. 

Hartzell's senior vice-president of marketing and customer services, Mike Disbrow said, "This STC approval means that our new propellers will be deployed with the very latest blended airfoil design, engineering and manufacturing technology.  Our R&D department is constantly striving to provide customers with advanced propeller design, and these propellers have shown significant improvements in take-off, climb and cruise performance."

The company claims that installation of the 82" diameter Scimitar 3-blade prop on the Cessna T/P210 Series typically offers a one- to three-knot increase in cruise speed, and a 4% decrease in time to climb to 23,000 feet, when compared to the originally-installed prop. It also reduces noise when compared to similar three-blade props. 

Available through Hartzell's Top Prop program, the 2010 list price for the kit with a polished spinner is $10,500 and are also available with 28-volt de-ice kits at an additional cost.  The new propellers also carry the Top Prop Plus Three warranty, good for three years or 1000 hours and have a six year/ 2400 hour TBO.  Top Prop offers over 60 different STC kits for a wide range of Beechcraft, Cessna, Mooney, Piper and other aircraft and has over 15,000 kits in operation around the world.
