I described a critical error I made in an earlier section (10-28) where I mis-drilled the holes where the vertical stabilizer attaches to the aft fuselage. The short story is I didn't line up the drill correctly, and ended up with an unacceptable hole through the vertical stabilizer rear spar and doubler. Fortunately, I stopped drilling before I reached the aft bulkhead of the fuselage; which limited the damage to just the vertical stabilizer.
I consulted Van's about the error and the tech support team responded that I needed to replace the rear spar and doubler. That doesn't sound too bad until you recognize that the way to replace the rear spar is to disassemble the entire vertical stabilizer. I knew that the chances of successfully removing every rivet in the assembly without damaging other parts was very low, so I decided to re-build the vertical stabilizer with all new parts.
