The OEM 3-blade Hartzell propellers on Hull’s King Air were due for an overhaul in January 2014. After consulting with International Propellers, Hull decided to upgrade to the Raisbeck/Hartzell Swept Blade Propellers. The installation took place at Silverhawk Aviation in Lincoln, Neb., where Hull also added Raisbeck’s Dual Aft Body Strake to complete the Raisbeck C90 EPIC Performance Package. The aircraft now has increased allowable takeoff and landing weights, improved FAA-certified takeoff and landing field length performance, higher engine operating ITTs for better climb and cruise performance, and overall quieter operations through reduced climb and cruise RPM.
After the first test flight with the new props and strakes, Mike Hull commented, “Nothing but good news: the strakes and props work absolutely perfectly! At 22,000 [feet altitude], I came back on the same power setting I normally use, except with 1750 RPM on the props with slightly warmer than normal OAT. I fly faster, quieter and probably 300% smoother. With the lack of vibration, my C90 rides more like a jet than a turboprop. Remarkable difference!”
