Hartzell Propeller Inc. and Cirrus Aircraft have entered into a five-year extension of an exclusive supplier agreement to provide propeller systems and governors for all of Cirrus Aircraft's new prop-driven airplanes. The agreement extends a relationship between the companies that began in 1996.

It was then that Hartzell began working closely with Cirrus to develop high-performance, low noise two- and three-blade propellers for the SR20 and later developed a new advanced three-blade structural composite propeller that helped launch the SR22. These propellers became the precursor for Hartzell's blended airfoil technology.

Under the extension, Hartzell will continue to provide Cirrus with three-blade metal propeller systems for the SR20 and SR22 and three-blade composite props for the SR22T, all single-engine aircraft. Hartzell expects to provide Cirrus with more than 250 propeller systems annually under the extension. Value of the contract was not released.

Hartzell Propeller President Joe Brown said, “When a leading manufacturer like Cirrus Aircraft, which specializes in advanced aircraft, selects Hartzell Propeller as its sole-source supplier of high performance propellers, we are gratified.”

"Cirrus is pleased to continue the productive relationship we have had with Hartzell Propeller for more than 15 years,” said Cirrus CEO and Co-Founder Dale Klapmeier. “The proven high performance and reliability are a perfect match for our advanced aircraft.”
