Piqua, Ohio, Feb 2, 2015 – Hartzell Propeller Inc. received a Supplemental Type Certificate (STC) from the Federal Aviation Administration for the company’s new state-of-the-art lightweight Scimitar prop for all Cessna 172RG Cutlass aircraft.

The newly designed and aggressively shaped Scimitar swept tip aluminum compact blended airfoil two-blade propeller and light-weight carbon fiber, all composite spinner assembly enhance standard-equipped propeller performance. More than 1,100 172RG aircraft have entered service.

“This new Cessna 172RG swept tip Scimitar propeller along with its robust aluminum compact hub gives the maximum lifetime and performance that aviators flying with Hartzell props have come to expect,” said Joe Brown, Hartzell Propeller President. “This two-blade lightweight prop has better tolerances and corrosion resistance than previously available.”

The newly engineered propeller from Hartzell has a globally acceptable takeoff noise profile of 84.9 dB(a), and a number of foreign STC validations are pending. The new propeller, part of Hartzell’s Top Prop conversion program, has a 2,400-hour, six-year recommended time between overhaul. Kit pricing for the new prop, spinner and STC is $9,500.

For the STC program, Hartzell Propeller was permitted to fly a Cessna 172RG Cutlass on loan from the Aeronautics Division at Kent State University’s College of Applied Engineering, Sustainability and Technology. The Kent State Aeronautics Program is home to the largest fleet of university operated aircraft in Ohio and is based at the Kent State University Airport in Stow, Ohio. The program has more than 500 students seeking degrees in Flight Technology, Aviation Management, Aeronautical Systems Engineering Technology, Aeronautical Studies and Air Traffic Control.
