Beechcraft Baron 55 owners who have been waiting for a three-blade Top Prop can rejoice. Hartzell said it has received supplemental type certificate (STC) approval for its propeller on the venerable twin.
Hartzell says the new propeller features aluminum alloy blades that provide increased ground clearance, less noise, and better speed. Owners should see a 5.8 dB decrease in sound over the standard two-blade prop, and 1.1 dB lower than other three-blade models. The company also says that users should expect a 2- to 4-knot increase in cruise speed, depending on the installation.
The kit, which includes new pointed, polished spinners, range from $21,500 to $26,850 depending on aircraft and options. Hartzell also said the propellers are fully compatible with 14 volt or 28 volt de-icing systems or alcohol anti-ice systems. There is a three-year, 1,000 hour warranty as well.

As the cold weather chills AOPA’s Headquarters in Frederick, many of us are inside generating new resources for flying clubs.
In my house, every Friday night is “Movie Night.” While the movies are rarely educational (I don’t think I learned anything from the Lego Movie), we look forward to the weekly opportunity to spend time together. Why not use the same concept for your Flying Club (with the addition of education, of course)?
AOPA Flying Club Manager Kelby Ferwerda posted the following on the AOPA Flying Club Facebook Page: “Recently I’ve talked with quite a few Flying Clubs about maintaining social activity through the cold winter months. Some clubs host Holliday Parties, others have Potluck Movie Nights. What does your club do to keep members involved during the chilly months?”
