That's also what I thought when I first read it , but I think that he
meant IA to mean "Instrument Airplane" rating.

Yeah, my bad. I did mean IA to be instrument airplane, and
only after I posted did I realize/remember that it means
something totally different.

However, the jaars.org posting that another fellow made
does actually require an A&P, though no the A&P w/ IA.
