Three-bladed top prop performance conversion for Beech 58 Barons

Three-bladed top prop performance conversion for Beech 58 Barons

Hartzell Propeller Inc. recently announced that it has received an STC to install a newly designed, three-bladed propeller system on Beech 58, 58A, and G58 Barons factory equipped with TCM 10-520 and IO-550 engines (Figure 1).

 Figure 1 Beech 58 Barons can now be fitted with the latest three-bladed Hartzell Top Prop conversion. The propellers feature Hartzell's proprietary blended airfoils and are offered with optional electric de-ice kits. The STC covers 58, 58A and G58 Barons with TCMIO-520 and IO-550 engines

The 75in. diameter three-bladed full feathering propellers are highly swept providing a distinctively new appearance for the Baron. The blades feature a proprietary Hartzell blended airfoil that was derived from Hartzell's seven-time winning Reno Sport Class air racing design. The objective of this new design was to improve the cruise performance of the Baron without sacrificing its take-off or climb performance. The reduced diameter also claims to provide the added benefits of increased ground clearance and lower noise.

The new Baron Top Prop kit comes complete with two propellers, two highly-polished spinners, STC paperwork and the exclusive Hartzell Plus Three warranty, which delivers a full three years or 1,000h of coverage. Hartzell de-ice equipment is available as an option for most of the airplanes that are currently equipped with an electric propeller de-ice system, including those applications approved for FIKI (flight into known ice). A new anti-ice system is in development for airplanes with alcohol systems, and will be available in the future.
