After inspection by Bruce a few weeks ago I was ready to replace a few rivets and close up the Vertical Stabilizer.
Completed the rivets for the bottom inspar rib, including the skins and to the spar.
Had an issue with the center front spar rivet. I needed to drill it out and enlarged the hole. Sent the question to Vans. Response is what I expected to move to a -5 diameter rivet.
