OK folks....Purdue had finally officially accepting bids for these A/C! Follow the link here:
http://www.purdue.edu/surplus/There's another link at the bottom of the page for the Aircraft Sales. There you'll find some contact info and a link to the actual bid sheet. I noticed the pictures don't seem to be working on the page, but both Chipmunks are listed on the registry with pics.
The University is also selling a Cessna 182 and both King Air B200s
I'm just posting this for you're information. Please use the contact infoo on the website if you have any questions, as I'm am not the authorized agent. I will say that I have personally worked on all these A/C, and I think our shop takes impeccable care of them. Just my 2 cents...
