The question on the 727 Tay conversion is far enough back that I put a new post up for this question.
You stated that all of UPS's 727's, save nine have the Tay engines. I am not up to speed on their fleet but my understanding is that most of the fleet are -100's, but yall do have some -200's too.
It was also my understanding that the Tay conversion was only available on the -100.
Are the nine aircraft without the Tay's -200's or where they certified also for the Tay engines? I remember in an old copy of Airways that there was a story about UPS and there where a couple shots with what appear to be -200's with extended tailpipes, Unfortunatly my Ex-girlfriend ended up with it so I can't reference it to get a page number for you.
Of course I could also be completly off my rocker about UPS flying -200's too.
