Interesting. MTO weight 41,000 pounds, yet classed as "L"... any
notions as to why there would be a discrepancy of this kind?


No idea.

Could it be like the 757 where it's something to do with the vortices
even though it's not a heavy?

The 757 was classified as a heavy for a while for wake seperation, but that
was rescinded a few years back. Still a good idea not to nuzzle up behind
one. It's wing is kind of unique in that the center section has a critical
foil and this causes a particularly strong spanwise flow.
The latest 737s have the same wing, BTW.
