Sometimes you just outgrow a name, as Kelner Turbine did. As of September the company is rebranded to CD Aviation Services. According to a company spokesman, the name change accompanies the introduction of a new facility in Calgary, Alberta. CD Aviation Services is an FAA-, EASA- and Honeywell-approved repair station that provides maintenance and repair services for Honeywell TPE331 and TFE731 engines and Honeywell/Sundstrand auxiliary power units.
