Hartzell: "Combines best aspects of original propeller with Hartzell's latest airfoil design capabilities."

Hartzell tells ANN that a new three-bladed propeller is now available for a wide range of Beech Bonanzas and Debonairs. The new propeller is a hybrid design to maintain the outstanding structural characteristics of the existing Bonanza blade while incorporating improvements in the tip section like those found on Hartzell's newer "Blended Airfoil" blades. The objective was to offer a larger diameter propeller for improved performance without increasing the noise signature of the propeller.

As a result, at 82 inches in diameter the new propeller is 2 inches larger than the previous Bonanza propeller and provides an increase in take-off and climb performance. Pilots are also reporting an increase in cruise performance. Like the previous Top Prop for Bonanzas, this propeller comes with a 2400 hour/6 year TBO and the exclusive Hartzell Plus Three warranty which provides a full three years or 1000 hours of coverage.

Cost for the complete kit is $8,995 and includes the propeller, polished spinner, and STC paperwork. The kit is available specifically for the 33, 35, and 36 series Bonanzas with originally equipped TCM 10-520 or 10-550 engines.

Carl Hinnewinkel of Cherry Valley, CA installed the new prop on a Beech V35B with the 10-520-BA and reports, "Take-off is excellent and climb is incredible. There's less vibration and it's much smoother. I've seen an increase in cruise of 7-8 knots. At higher altitudes the take-off is really incredible."
