In the United States a number of conversions have been made to aircraft to change engines and increase performance. One company carrying out this type of conversion is Texas Turbine Conversions which converts de Havilland Otters to turbine power, and fits Honeywell TPE-331 turboprops to Cessna 208 and 208B Caravans
With numerous Piper Apaches and Aztecs having been adapted for commuter airline type work in the early 1960s, it was expected, when Piper unveiled the Navajo as the first of a new breed of twins, that variants would be built to meet the needs of the growing commuter market.
