He is. Has never flown a single.

It DOES sound weird tho.. You would think the ATP would override
the commercial multi CLT..

That's what I thought. Granted, he *could* just be carrying around the
invalid commercial, assuming it's still valid. Not sure what good it is.

As for which one it adds on to: My guess is.. which ever one he wants..
He can train for a ASEL ride to private, commercial or ATP standards
provided he has the time in type for the add-on. (havent looked at the
applicable reg for this one as to any required hours).

I'm trying to make it make sense by thinking of it how I did it. I had
a commercial single and just added the multi on. I believe it's the
same thing, no? He wouldn't have to go approaches, since that's a
commercial multi thing, but he'd had to add it at least at the
commercial or ATP level, because that's what he already has.

At least, as far as I can tell.
