McCauley Propeller Systems, a division of Textron Aviation, is making its C780 propeller, which had previously been optional for factory installation, standard for all new commercial customers of the Beechcraft King Air 360. The first King Air 360 equipped with the propeller recently rolled out of production at Textron Aviation's factory in Wichita, Kansas.

“As a leading full-line propeller manufacturer, being featured on the factory line of the legendary Beechcraft King Air 360 underscores our commitment to excellence,” says Jason Hull, vice president and general manager, McCauley Propeller Systems. “The C780 offers a sophisticated and durable design that aligns with the versatility of the King Air turboprops. We look forward to continuing to support this iconic family of aircraft and pilots around the world.”

The C780 propeller, which entered service in 2023, features a lightweight scimitar blade design with four aluminium swept blades and a 105-inch diameter. The high-performance propeller provides King Air B300 owners and operators with several benefits to their aircraft, including: propeller weight savings of up to 50 pounds compared to previous options; reduced noise in the cabin and cockpit; extended Time Between Overhaul (TBO) of 5,000 hours or 72 months; and Textron Aviation's 5,000 hours or 36-month limited propeller warranty.

The C780 propeller achieved FAA certification in 2023 and EASA certification in 2024. It also recently achieved certification from ANAC, the Brazilian civil aviation authority, the second largest installed base for Beechcraft King Air turboprops.

Current King Air B300 owners can have the propeller installed on their aircraft at a Textron Aviation service centre or authorised McCauley service facility without any additional modifications required.
