Columbia 350 Equipment Details


Teledyne Continental Motors (TCM) IO-550-N

The Teledyne Continental Motors IO-550-N engine installed in the Columbia 350 is a six-cylinder, 310 horsepower, naturally aspirated, horizontally opposed, air-cooled engine incorporating design features aimed at improving performance and economy. The IO-550-N incorporates cross-flow cylinder design that improves the flow of gases through the combustion chamber enhancing the combustion event. Also incorporated on the IO-550-N is a balanced intake system that provides equal air distribution to each cylinder. This balanced air distribution system, coupled with the TCM Fuel Injection System, optimizes the output of all six cylinders, providing the most power available with the lowest possible fuel consumption. The components of the IO-550-N are produced in the largely-vertically-integrated Manufacturing Excellence center at TCM’s headquarters on the latest in computer-controlled manufacturing equipment. Using the latest in computer controls and monitoring, the IO-550-N is produced to tight variances on critical components and engine characteristics that result in an engine that is essentially blueprinted direct from the factory. TCM offers week-long factory training courses open to the owners of Columbia aircraft and welcomes customer tours.
