Dunno about 38, but the newer ones have 30, because full 40 degree flaps were
causing problems (which I can't recall) due to poor technique of some sort.

Might have something to do with slips with flaps, IIRC.

Yep, slips with flaps was part of it, but a nose high attitude with
full flaps on go-around is what bit most of the people before they
changed to 30.

This month's edition of Flying has a good article by Richard Collins
about landings and a lot of the article is devoted to the use (or when
appropriate, the non-use) of flaps
