Raisbeck Engineering announced this week that it had received Supplemental Type Certificate (STC) approval from the Federal Aviation Administration (FAA) for its Composite Five-Blade Swept Propeller for the Beechcraft King Air 200 series aircraft. The STC approval paves the way for the company to begin deliveries to King Air 200 owners and operators in December. 

Designed to improve performance and passenger comfort, the new five-blade composite propeller delivers more than 15 percent greater takeoff acceleration, over 20 percent better climb rate and a 30% noise reduction throughout the aircraft.

Manufactured by Hartzell Propeller and constructed of structural carbon fiber composite with nickel cobalt leading edges to protect against foreign object damage, the Composite Five-Blade Swept Propellers optimize airfoil efficiency allowing for a larger 96-inch diameter propeller with less blade tip noise. The new propeller system also offers King Air operators an average of 48 pounds total weight savings versus factory-standard propellers and features unlimited blade life, thereby lowering maintenance and overhaul costs. 

“We’re very excited about this latest performance improvement certification for the King Air 200 aircraft,” said Raisbeck President Lynn Thomas. “Our new composite five-blade propeller will enable King Air owners to take advantage of a broader offering and more opportunity to upgrade the performance of their aircraft.”

The Composite Five-Blade Swept Propeller made its public debut Oct. 22, 2019, at the National Business Aviation Association’s Convention & Exhibition (NBAA-BACE) in Las Vegas, Nevada. STC approval efforts to begin immediately for European Aviation Safety Agency (EASA), Transport Canada and the National Civil Aviation Agency of Brazil (ANAC).
