Note that for the 767-2C/KC-46 it's very likely the case that the 767-2C wouldn't share a common type-rating with the rest of the 767 family (as this wasn't a requirement for the KC-46 contract!), and for the 737 MAX a lot of design decisions were driven by the desire for the 737 MAX to have a common type rating with earlier 737 models. From the 767-2C type certificate: > The Boeing 767-2C has not been evaluated by the Flight Standards Board. No pilot type rating or training, checking and currency requirement determinations have been made. Note the only 767-2Cs built were to certify the type, no airline has ordered the freighter aircraft.
