Not viable for Grob to return some to service (9 + 6?) with a Rotax in the front, and recoup that money by doing less work to the rest and selling them. Don't forget they would have to certify the Rotax mod and provide mod kits, and work to the unusual MoD engineering policy. How much is a G109B worth, that has been operated over the TC max weight, on the open market? How easy would it be to sell 50ish aeroplanes? Its a risk and reward equation, too much risk, not enough potential reward = financially not viable. Only speculation from piecing together the various rumours.
