Sierra Industries Ltd. has amended its Cessna 206 Long Range Fuel System STC, allowing the installation of the wing tank modification to the turbine engine upgrade from Soloy Aviation Solutions. Sierra’s STC amendment is applicable to the original Soloy Turbine Cessna 206 Mark I and the new Soloy Aviation Solutions Mark II aircraft.
Sierra’s Long Range Fuel System adds approximately 50 gallons additional fuel capacity to the original specifications and provides up to 2 hours of additional cruise time. The Auxiliary Fuel Tanks are manufactured from vulcanized rubber and integrated with the existing fuel system, with no additional switches or fuel gauges required, according to Sierra officials.
The fuel system is available in kit form for field installation. Installation by certified FAA mechanics is also available at Sierra’s facilities in Uvalde, Texas. Kit pricing for the Sierra Auxiliary Fuel System starts at under $13,500.
Soloy Aviation Solutions’ Mark I installs the Rolls-Royce 250-C20S turbine engine and Mark II installs the Rolls-Royce 250-B17F/2 turbine engine. Improved overall performance and reliability as well as quieter operation are hallmarks of the engine modification. Both the Sierra fuel system modification and Soloy turbine upgrades are available for Cessna U206G, TU206G, 206H & T206H aircraft from 1977 models to present.
