The O-470 is one of the numerically most important engines in today's light aircraft. In particular, it has powered many of the models in the Cessna and Beech ranges since the 1950s. Through its development - which still continues - its power has been increased from 165 to 240 HP through a number of engineering refinements, and a fuel injected version, the IO-470, delivers up to 260 HP.
