No such thing as MCCI(H) - stupid anomaly, because the assumption is that all TRI(H) and SFI(H) are automatically competent to teach MCC. Best bet if you need a multi-crew TR is to do an integrated TR and MCC course. That way you get to practice multi-crew procedures on the type you are learning, not on some random generic FTD. Also you get some hours exemptions if you do it all on the same FFS. Ask your TRTO - they should be able to advise.
