Yes, Bose-X and 2Donkeys, you are both correct. There has to be at least 20% before TBO left on the engine to import it and fit straight on to an aircraft. Therefore you could not fit our engine directly onto an aircraft without overhauling it. Our engine would suit someone whose own engine was approaching TBO and who wanted to source another engine to overhaul and have ready to fit when their engine reached TBO.
