Davis Aviation Services, Inc., now offers the STC to convert your Cessna 206 to the IO-550 with the various propeller options!

Formerly known worldwide as the "Bonaire 550", this conversion provides for the upgrade to the IO-550 engine. With either the McCauley or the Hartzell propeller option, performance is phenomenal with shorter takeoff roll, increased rate of climb, and faster cruise speeds.
