I am replacing a rotted drain trap and when removing it, the end of the trap where it is secured to the nut on the floor drain broke clean off so that the threads from the trap pipe are still in the nut and I can't install the new trap to the old nut. Any tricks to keep the job from getting bigger?

Not sure that you are using the right words for what you trying to say. Are you talking about a trap or a clean-out plug? Traps are not usually screwed into floor drains.

Sorry for the bad vocabulary. Here is a picture

the pink handle is pointing to the nut where the old trap pipe broke (not shown) and left its threads in the nut.

That is in fact a trap. It is called a "full s trap", and you will need to get to the bottom of the pipe that goes through the base of the cabinet and replace the whole thing. If you are lucky there will be a slip joint in the basement that you can access.

the best thing would be to replace that piece also as it is not in much better shape than the piece you removed by the looks of it

the bad news is you'll have to replace that pipe. the good news is you can cut away some of the vanity base to get access to the connection. the bad news is that the connection might be below the floor.
if as shoemaker thought, there is a fitting below the floor in the basement, the job is very easy. if not, it is probably too complicated for a homeowner but a plumber could do the job in less than an hour (if you cut floor etc for him)

Is it inside a kitchen island?

The good news is that someone had to have connected that pipe to the drain system, so that connection should NOT be inaccessible. The bad news is that you may not find a replacement "S" trap, unless you are in an area that has a multitude of them so that the hardware stores will stock them even though they are illegal and no longer used in most places.

Expert plumbers is this a plausible approach?
1. make square cut on metal drain
2. use fernco to adapt to short piece of ABS or PVC pipe
2. install San Tee and AAV for venting
3. plumb in new p trap and tail piece to fit
Would eliminate the need to go under floor at all.

You would still have the worn piece of tubular piping to fail in the near future

I was afraid the consensus would be to go to the drain pipe in the basement. As that was out of my league and budget, I went the fernco route. I am hoping to get another year or two before the next section fails. Thanks for the feedback - you guys rock.

It would not be the best approach, especially if that tubing is as bad as it looks like it is.

so much for giving you our advice as to the best approach. You could have done that without even asking us for an opinion.

it is still an s-trap so you still need to vent it I would believe.

that depends sum, this house was most likely built when they were still using s-traps according to their code so it might be grandfathered to where just replacing the trap does not constitute tearing up the house to install a vent that wasnt necessary when it was originally installed.

Grandfathering it means you do NOT have to change it, but when you DO change it the grandfather permission is voided. Sometimes just changing ownership is enough to trigger a requirement to update it.

not usually unless you are also replacing where it ties into the drain line. at least in my area that is the way of it.

It IS however the building department wants it to be, but that does not mean it is always done that way.

i dont know how it works where you are but here the building department follows what the city council votes as the code

would an AAV right there be the most simple solution?

It could be, but there are situations where an "S" trap, or an AAV, (and an "island"/yoke drain installation for that matter), could prevent drainage even though the sink pipe is not plugged.
