Hartzell awarded TC for two-blade Bantam prop for Rotax engines

Hartzell Propeller has received a Type Certificate from the Federal Aviation Administration for the new two-blade extremely lightweight Bantam propeller for use with the Rotax 912 and 914 four-stroke engines series, used mostly for light sport and ultra light aircraft.

“The Rotax 912 and 914 series of four cylinder four stroke engines perform even better with Hartzell's new two-blade Bantam prop,” said Hartzell Propeller Joe Brown. “This will become the propeller of choice for many light sport and ultra light aircraft.”

The Hartzell Bantam propeller series consists of small, lightweight two- and three-blade propellers with a thin, wide chord and swept high performance airfoils. The recent approval covers installation of Hartzell's two-blade Bantam propellers, featuring carbon fiber structural composite blades, hard nickel leading edges and composite spinners.

Hartzell representatives will be in Germany at AERO Friedrichshafen April 15-18 to discuss the latest Bantam Type Certificate. Hartzell will be exhibiting at Hall-Stand A3-124.

The new propellers are available in various diameters ranging from 67-77 inches through Hartzell's Top Prop performance conversion program. Bantam two-blade props are approved for 912iS Sport (100hp), 912 (80hp), 912 (100hp) and 914 (115hp) engines. Lightweight Bantam two-blade propellers weigh only 25 pounds, including spinner.

Superior strength of the carbon fiber structural composite material enabled the Hartzell Propeller engineering team to design blades with wider chords and thinner airfoils, ultimately leading to higher performance and durability.
