As of right now it is not certified S/E charter, but it is based off a proven design (CT7/T700) which is the donk in the Apache - as well as other parts and components based off other commercial designs in their line-up, so should not be long or difficult to get approved for S/E charter as these components have all proven their reliability. - The fact it is aimed in direct competition to the PT6 and will power the Cessna Denali which is aimed at the PC12 market I am sure S/E charter approval is what they had in mind the whole time.
