Looks like a single engine piston rating would be the cheapest to maintain as it remains current for 2 years as oppose to 1 year on the Multi Engine piston. An IR on the SEP every 6 years should prevent the need for a retake of the IR exams, until they change the rules again of course. Anyone know if there's any rules that prevent maintaining an EASA ATPL with an SEP/IR or does it have to be MEP or Multi-crew ?
