Commuter Air Technology Offers Composite King Air Props
New composite propellers will improve the performance of King Airs.

U.S. modification specialist Commuter Air Technology (CAT) has signed a contract with Finnoff Aviation Products to provide five-blade MT composite propellers for Beech King Air 90s, 200s and 300s, the companies announced in Paris this week. Terms of the agreement grant CAT exclusive rights to sell MT Propellers to U.S. Department of Defense customers and to customers of foreign governments for which the U.S. serves as the contracting and/or financing agent.

MT’s composite airfoils feature a smaller propeller diameter and thus shorter blade size, which reduces noise due to slower tip speeds and increases the margin of safety between the blade tip and ground. The additional surface area of a five-blade propeller along with the slower tip speeds help to maintain smooth airflow over the blades and result in greater thrust for takeoff and climb.
