Raisbeck Engineering has received Supplemental Type Certificate (STC) approval from the FAA for its new Composite five-blade swept propeller for the Beechcraft King Air 350.
The composite propeller, designed to improve King Air comfort, performance and efficiency, was developed in collaboration with Hartzell Propeller. At 106 inches in diameter, Raisbeck’s propeller reduces weight and contributes to improved short field and climb performance, while providing strength and durability expected from modern composites. The new composite propellers have an extended 3,000-hour, three-year warranty and unlimited blade life.
“This is a significant milestone in our journey to market entry for a composite five-blade swept propeller,” said company CEO and Chief Financial Officer Tony Armstrong. “We couldn’t be happier and our new propeller will further enhance the King Air 350 performance. We believe King Air operators will truly enjoy flying with these new propellers”
The propeller, which are available for immediate delivery, provides a total weight savings of 47 pounds compared to the current OEM propeller for the King Air 350.
