Raisbeck Engineering Receives STC Approval for Composite Five-Blade Swept Propeller.

September 14, 2017 – Seattle, Wash. – Raisbeck Engineering, a leading

provider of performance enhancement systems for business and

commercial aircraft, is proud to announce the company has received

Supplemental Type Certificate (STC) approval from the FAA for its new

Composite five-blade Swept Propeller for the Beechcraft King Air 300/350.

The composite five-blade swept propeller, designed to improve

King Air comfort, performance and efficiency, was developed in

collaboration with Hartzell Propeller. A 106-inches in diameter,

Raisbeck’s composite five-blade swept 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 company received FAA Parts Manufacturing Approval (PMA) following STC approval and propellers are available for

immediate delivery.

Raisbeck’s aerodynamic blade design which optimizes airfoil efficiency combined with carbon fiber structural design,

maximizes thrust therefore increasing performance while reducing noise for the aircraft. The composite five-blade swept

propeller provides a total weight savings of 47 pounds compared to the current OEM propeller for the King Air 300/350.
