...and iirc the opposite of this is also true, i.e. you can be PIC of a Part 121 flight with only a CPL if the aircraft is smaller than this - which means that an ATP-ASEL is essentially useless. (I was researching exactly what you do need an ATP for a while back and I'm pretty sure I found this, though I can't say exactly where).
135.243(2) is kind of interesting... what happens if someone wants to operate scheduled interstate services in an R66, for which there is no type rating (assuming SFAR73 doesn't count) nor is it permitted for IFR operation. Hard to see why anyone would, but then rules aren't supposed to be written around what people actually want to do.
