Sorry about your Father...
A fellow here just lost his Aurora from a failed wing...Apparently the sheeting came loose and it broke just beyond the fiberglass center section...Here is a link to the thread if yoiu want to take a look:

I'm going to do a new set of wings for my Atlanta...Some of my others I'm going to keep a close eye on...
Maybe you could get some cores and do another set of wings only??
Take Care...
