Hartzell Propeller is expanding its commitment to the general aviation community in 2026—making high-performance propeller upgrades more accessible, more affordable, and easier to navigate than ever before. Through a major expansion of its popular Top Prop conversion program, Hartzell unlocks a new upgrade path for thousands of aircraft owners. With more than 150 additional propeller models now included, pilots have greater access to both aluminum and advanced carbon fiber propellers designed to deliver improved performance, efficiency, and durability.
JJ Frigge, President of Hartzell Propeller commented: “The Top Prop conversion program continues to evolve based on feedback from the aircraft owners and operators we have worked with for decades. By enhancing the portfolio with more than 150 additional propeller models and improving pricing across the lineup, we have made it easier than ever for pilots to upgrade to Hartzell performance, backed by an industry-leading warranty through first overhaul.”
Hartzell is reaffirming its support for the general aviation community through continued partnerships with the Aircraft Owners and Pilots Association and the Recreational Aviation Foundation , including renewed discounts on new Top Prop installations.

The expanded Top Prop program brings together a wide range of STC and aftermarket propeller options into one comprehensive solution—giving pilots more upgrade choices at more competitive price points than ever before.
With the addition of more than 150 propeller models to the program, Hartzell brings high-performance upgrades to a broader range of aircraft owners. Improved pricing across key platforms, combined with an industry-leading warranty through first overhaul, delivers compelling long-term value for operators focused on both performance and cost of ownership.
A newly enhanced search experience allows users to identify compatible propellers by aircraft, engine, and model year, with optional filtering by certification authority (FAA, EASA, and others worldwide)—bringing clarity to the upgrade process and helping pilots confidently select the right solution for their mission.
