In the midst of marking its 85th year serving the aviation industry, McCauley Propeller Systems celebrates an important milestone. The division of Textron Aviation announced the first delivery and entry into service of the C780 propeller on the Beechcraft King Air B300 series—bringing the twin turboprop’s means of propulsion “into the family.”

The option joins McCauley props available on the B200, as well as B300 choices from Hartzell, MT Propeller, and others.

The 105-inch-diameter, four-blade aluminum, swept-blade prop system achieved type certification in July.

At a media briefing on Tuesday in Wichita, Kansas, the Textron Aviation team expressed its enthusiasm for McCauley’s achievement, likening it to the type certification of a new aircraft model for either of its aircraft brands, Cessna, Beechcraft, or Bell.

“The new McCauley C780 offers King Air customers increased performance, a quieter cabin, and greater efficiency,” Heidi McNary, vice president and general manager of McCauley Propeller Systems, said in a statement. “For 85 years, McCauley has been committed to delivering creative solutions and driving customers forward with their pioneering designs and strategies. We look forward to continuing to support the future of flight and legendary aircraft like the Beechcraft King Air.”

The first installation went on a King Air 350 owned by ExecuJet Charter Service in Florida, a private Part 135 charter operator. Interested owners can seek out the installation at Textron Aviation Service Centers or authorized McCauley service facilities.
