W27x181 was dropped because it was dropped in the source list (ASTM A6) to
which structural shapes areproduced. Said more simply, producers cut it out
of their list of shapes, so we did too.
That said, it appears that producers are fickle (no insult intended). I
just noticed in the January issue of AISC's Modern Steel Construction shape
availability list that it is again available. The dimensions and properties
are consistent with that in you older Manual.

Does anyone know why the W27x281 - and some other shapes - do not
the 2nd Edition of the LRFD? They do appear in the 1st Edition of the LRFD
in the ASD books. Have some of the less popular shapes been phased out
recently? I'm looking at some shop drawings with that section, and no one
complained about it... at least not yet...
P.S. No, I don't mean to continue the LRFD versus ASD discussion with a
shapes" thread - just wondering where my W27x281 went.
