I've been getting ready to install the wings on my 9A and I was checking to see how the close tolerance bolts fit through just the wing spar. There was only 1 hole out of 16 that was so tight I did not think the bolt would go through. I had to keep hitting it with a rubber hammer and then tapping it back out. Repeat until it finally went through. You can see how the bolt looks after all this. All the gold plating is gone.
I have not checked the center section yet, but that's on the list. I figured if they didn't go through separately, it was going to be a long day trying to get them installed and aligned to both. This image shows where it started to get very tight.
This is what the bolt looks like afterward compared to a bolt not previously installed.
