A couple of years ago, when I was previously working on this part of the project, I had the brilliant idea to add an Adel clamp to hold the plastic tubing that I used to protect the flap motor wiring under the armrest. I used my best guess to determine that it would be OK to drill a hole for the attachment bolt inside the well where the flap would retract. Unfortunately, my guess was off by about an inch. So today, among other projects, I fabricated a patch, and bonded it over the hole in the inside of the fuselage skin under the floorboards on the left side. Tomorrow, after the adhesive cures, I will make the "outside"of the hole disappear with SuperFil. No harm done, in this case. But dang, I hate it when I'm stupid.
