Thanks everyone for the advice. I really appreciate it.
I did initial inspection today, more to come but so far everything seems good for the most part.
Logs all are up to date from what I've seen so far with STCs and P/Ns matching as they should. Wing spar in cabin and wheel well is in good condition, no notable corrosion found. Interior and exterior, including in inspection holes all looks great. I checked all flight controls for smooth, correct movement as well as excessive play in the rudder, horizontal stab, and flaps and they all look tight. I did a compression check on the cylinders and they all read nicely even after not running for quite awhile, better than expected. No notable leaks, cracks, etc in engine as far as I can see.
The only issue I have found is some light rust on super structure cage in the cabin, so far it doesn't seem bad. I think I should be able to polish it out with steel wool and coat with zinc chromate primer as none of it seemed very deep.
I still need to put it on jacks to check the compression disks but with it on the ground they seem to be in good condition. I plan on jacking it within the next few days. I also plan on doing a borescope inspection of the cylinders before I jack it.
