Davis Aviation Services, Inc., now offers the STC to convert your Cessna T207 to the IO-550 with the various propeller options!
Davis Aviation Services, Inc., owns the STC for the upgrade for the Cessna T207 from a TSIO-520 engine to the normally aspirated IO-550 engine. (Removal of the turbo charged system)
This upgrade was designed for aircraft owners who own a T207 but are not flying high altitudes. The combination of the IO-550 engine (300 HP continuous operation @ 2700 RPM) and a three blade propeller will equal or increase the performance of the aircraft in normal operation. You will be able to maintain the service ceiling of the standard 206 and get away from the expensive maintenance of the turbo charged system. In the long run you should see a decrease in your cost to operate this aircraft as the fuel consumption and maintenance costs should be less. A long hub propeller option is also available.
