The three-blade carbon fiber composite propeller now available for most Bonanza A36, G36, and A36TC models.
Key Takeaways:
• Navigator STC expands to include most Bonanza A36, G36, and A36TC models
• STC available in popular 3-blade carbon fiber composite configuration
• STC excludes Bonanzas with the Continental IO-520-BA engine
PIQUA, Ohio, (July 21, 2026) – Hartzell Propeller, a Signia Aerospace company, has expanded the supplemental type certificate (STC) approval on its new Navigator carbon fiber propeller series for thousands more Beechcraft Bonanzas. With the latest in carbon fiber performance, ramp appeal, and proven Hartzell engineering quality and support, the next upgrade for Bonanza owners is clear.
The three-blade prop offers carbon fiber lightweight blade technology, which results in a measurable increase in overall performance along with a decrease in weight. The carbon fiber blades reduce airframe vibration, which results in a smoother flight and less pilot and passenger fatigue upon arrival at your destination.
Covered by the industry-leading Top Prop Warranty through the first overhaul, the Navigator prop extends the peace of mind for Bonanza owners on more versions: Hartzell will now be offering the Navigator on all Beechcraft Bonanzas with the IO-550-B engine and the A36TC with the TSIO-520-U(B) engine (not applicable to models with a Continental IO-520-BA engine). Early Bonanzas converted to a D’Shannon or GAMI IO-550-B engine are covered under the amended STC.
JJ Frigge, president of Hartzell Propeller, commended the extension of this important Top Prop program. “Bonanza owners have always appreciated quality, precision, and performance,” said Frigge. “Expanding eligibility of the Navigator to thousands of additional Bonanzas gives more owners access to our advanced carbon fiber propeller technology, offering a premium upgrade that enhances performance while adding meaningful long-term value to their aircraft.”
The complete STC kit includes an 80-inch diameter, three-blade carbon fiber propeller with polished spinner and all associated documentation. Total weight of the prop and spinner is 63 pounds, which translates up to a net 7 pound reduction in weight, depending upon the model airplane and prior propeller and spinner assembly it replaces.
