Registration question

I'm reading the FAA CD for a Tcraft.
I see in '90 that it sustained substantial damage, was deregistered as
'totally distroyed', then sold.
Apparently someone resurrected it, because it was sold several years
later using the same N number and it's currently flying in Florida.
The CD (BTW) doesn't show any of what must have been major major work
performing this resurrection (my only reference is the CD; I haven't
seen the logs yet)

There doesn't seem to be the audit trail I'd like; I see a stream of
ownership, but although there is a document saying 'please deregister
this aircraft' there is nothing saying 'pick me back up'.

Should I be concerned? - Mike
