New five-blade prop for King Air 350s

July 24, 2017 By Dave Hirschman

Raisbeck Engineering and Hartzell Propeller have teamed to produce a new, five-blade propeller that improves the performance of King Air 350s while reducing cabin noise.

Raisbeck officials say they expect an FAA supplemental type certificate "very soon," and the company already has orders from two separate firms.

The new propellers are made from carbon fiber, and they are about 47 pounds lighter than the four-blade, metal propellers they replace.

Company officials said single-engine climb performance increases between five and seven percent with the new propellers.

The new props are expected to sell for about $140,000 per pair, Raisbeck officials said.
