Every inspector is a bit different
Every inspector is different. My inspector was totally fine with mirror and flashlight. Schooner69 is bang on with his comments. You may not know your inspector at all when he first comes to visit. But fortunately the empennage is a pretty clear line to determine what to leave open. As Sledrider says leave the rear spar off on the HS and VS. Also, rivet the elevator frame together, but do not rivet the skins on the frame (rivet the counter balance skin on the skin with those two inner rivets you can't get when all closed up).
Once you inspector shows up he can easily see everything. Then start asking him about what he wants to see on the wings, and the fuse. write it down. Also ask if its ok to call him in a year or so just in case you have a question about what he wants to see. I did exactly this and my inspector was glad to help....but I was darn certain about following his every request. Nothing goes further in building trust then sticking to his request's even if you think they are odd or un-needed.
A fun one you will need to figure out is how to inspect the fuel tanks...do you close it all up, do you encapsulate the shop heads, but leave the back baffle off, or do you leave it all open for inspection. Best to confirm these details with you inspector as you build.
I have heard three different directions given by three different inspectors. They are not wrong....perhaps they have different experiences, or they see things in some peoples builds that make them want to check a little more then the next guy. I'm the same when I do inspections for work....i don't inspect every job the same, but when I see things that make me worry, I dig deeper or I ask that they call me more often to site.
