Hartzell Propeller has extended the propeller service warranty on newly purchased Raisbeck Engineering STC performance upgrade packages equipped with new Hartzell props for King Air aircraft.

The updated coverage now provides an industry-leading warranty through first overhaul at six years or 4,000 flight hours, whichever occurs first, up from the previous standard of one year/1,000 hours for aluminium propellers and three years/3,000 hours for composite propellers.

This new warranty extension applies to Raisbeck STC upgrades with Hartzell Propellers across a wide range of King Air models. It covers all Raisbeck configurations, including the original power props, the four-blade swept aluminium propellers and the advanced five-blade composite propellers for the King Air 200 and 300 series aircraft.

Raisbeck performance upgrade options span both Hartzell's four-blade aluminium and five-blade composite propeller configurations, offering operators top-tier reliability and performance, backed by best-in-class warranty protection through first overhaul. Raisbeck customers can pair this new warranty extension with Hartzell Service Center's standard warranty to add an additional two years/2,000 hours, when the overhaul is completed at a Hartzell MRO service facility.

“This warranty enhancement is a testament to the confidence Hartzell has in our propeller technology and manufacturing processes,” says Hartzell Propeller vice president, sales and marketing Jon Stoy. “We are proud to support Raisbeck King Air operators with unmatched reliability, value and now the longest warranty in the industry for STC propeller upgrades. It's another step in delivering total propeller support through Hartzell Propeller and Raisbeck Engineering.”

Gregory Davis, president of Raisbeck Engineering, adds: “Our work with Hartzell Propeller continues to deliver exceptional upgrades for the King Air fleet. This greatly extended warranty reflects our shared commitment to quality, innovation and customer satisfaction. Operators can fly with even greater peace of mind knowing their investment is protected through first overhaul and beyond.”

All Hartzell Propellers are manufactured in Piqua, Ohio, and supported through the company's extensive global network of service centres. Strategically located throughout the world, Hartzell's recommended service facilities and MRO service facilities provide owners and operators easy access to a repair centre.
