As the global leader in advanced aircraft propellers for more than a century, Hartzell Propeller is driven to set new standards for quality, performance, and support—and we’re proud to collaborate with partners who share our vision for advancing aviation technology.
One of those key partners is Raisbeck Engineering, a leading provider of aircraft modifications for business and commercial aircraft. For over a decade, our engineering experts have teamed up to reimagine the capabilities of the Beechcraft King Air family with innovative propeller upgrades.
Headquartered in Seattle, Washington, Raisbeck Engineering was founded in 1982 by James Raisbeck, an aeronautical engineer who dreamed of improving existing aircraft with products that would enhance performance capabilities, safety, and passenger comfort. His decision to focus on the Beechcraft King Air family of aircraft put Raisbeck on the map as a leading aircraft modifier, and several products Raisbeck developed have been incorporated into the King Air OEM production line.
Today, Raisbeck still provides performance enhancement systems for the entire Beechcraft King Air family, as well as a number of modifications for several other aircraft types.
Over the years, Hartzell Propeller’s engineering team has partnered with Raisbeck to develop several propeller advancements that complement their performance systems for the Beechcraft King Air.
First introduced in 2014, the initial Hartzell/Raisbeck aluminum swept aircraft propellers were highly praised for their quietness, performance, and impressive ramp presence for the King Air 90, King Air B200 series, and King Air 300 series aircraft.
Hartzell and Raisbeck continued collaborating on propeller blade technology advancements, debuting a 5-blade composite swept blade prop for the 200 and 300 series Beechcraft King Airs. With lightweight, durable carbon fiber composite propeller blades, the composite propeller upgrade led to an increase in take-off, climb, and cruise performance with decreased noise.
In 2023, Raisbeck Engineering received FAA STC approval for the installation of Raisbeck/Hartzell five-blade swept turboprop propellers on heavyweight (16,500 lb.) King Air 300, 350, and 360 series aircraft, which are often used for Air Ambulance and ISR missions. Constructed of carbon fiber composite and nickel cobalt leading edges, the durable propellers provide unlimited blade life while coming in at 54 lbs. less than the OEM propeller.
If you’re ready for a propeller upgrade or exploring modifications to help your King Air aircraft fly faster, carry more passengers or cargo and improve flight range, check out what our partners at Raisbeck have to offer. With over 140 authorized dealers worldwide, it’s easy to get started.
