Sept. 20, 2023
The lightweight, aluminum four-blade system achieve more than 50 pounds of weight savings and improve takeoff and climb performance for B300 turbo-prop private aircraft.

Textron Inc.’s McCauley Propeller Systems is supplying a new, “lightweight, scimitar-blade design propeller” for Beechcraft King Air B300 series twin turbo-prop aircraft. The 105-inch propeller features four swept blades formed in aluminum, achieving weight savings of more than 50 pounds versus the previous standard design for those corporate and utility aircraft.

According to the propeller manufacturer, the C780 propeller will improve takeoff and climb performance for the King Air B300 aircraft, and achieve time-between-overhaul of 5,000 hours or 72 months.

King Air B300 operators can have the propeller installed on their aircraft at a Textron Aviation Service Center or authorized McCauley service facility, with no additional modifications required.

The new design gained Federal Aviation Administration type certification in July of this year. With more than 350,000 installations worldwide, McCauley propellers are FAA-certified as original equipment for aircraft built by Textron Aviation, British Aerospace, Fairchild, Grumman, Jetstream, Piper, and others.

“The new McCauley C780 offers King Air customers increased performance, a quieter cabin and greater efficiency,” stated McCauley v.p. and general manager Heidi McNary.
