I'm still missing something here. 91.175 doesn't say when you have to
do a procedure turn, just when you can't. The erroneous AIM doesn't
conflict with 91.175 as far as I can tell.

Read it as you choose.

But why do you choose it one way and not the other? Is there another
regulation out there, or just 91.175?

I choose ro read it the same way the industry and FAA charting folks
read it over and over at the semi-annual Aeronautical Charting Forum
held in Washington, DC.

The other regulation is the fact that the IAP is issued under Part 97,
and when a course reversal is specificed on that regultory form, and the
arrival is to that course reversal segment rather than a terminal route
designated "NoPT," the course reversal is a mandatory part of the
procedure set forth by the Part 97 regulation for that IAP. 91.175(j)
is the only regulation that trumps the course reversal component of the
Part 97 regulation for any given IAP, and 91.175(j) makes its three
exceptions clear. One of those three exceptions, an NoPT intitial
approach segment, is also set forth on the Part 97 regulation for the
IAP. Your copy of the Part 97 regulation is either a NACO or Jeppesen
approach chart. The official regulation is on either an FAA Form 8260-3
or 8260-5, and inacted by reference in the Federal Register, just like
any amendment to an FAR.
