I looked thru http://www.faa.gov but >couldn't find anything relevant, unfortunately. They did not receive new type certificates. The MD-90 was added as a new model to the existing type certificate. Also, nothing has eased up for as long as I can remember. There are numurous type certificates with multiple model designations on them, many of which have existed for quite a long time. In response to another post, the airworthiness certificate diplayed in the aircraft has little to do do with what models are listed on a Type Certificate and its associated Type Certificate Data Sheet. The only requirement is the model designation is shown using the same designation as the TC and TCDS.
