New way to screw up
I try to be as original as possible when making mistakes, but here is one for the record: I am installing wing tanks and while smoothing out an inspection plate on the bottom of the wingtip I kept seeing blue color showing up in the filings. Stuck my head in, and you guessed it, I apparently forgot to remove the blue plastic!
Now comes the question. I can of course remove that piece and take the plastic all off, or I can remove it from that which I can now get to, or I can just ignore the whole thing. What say ye?

And here is the view from INSIDE the wingtip, I still can't believe I done that!

The plastic has to all come off. Otherwise it will over time trap a toxic brew of water, salt, etc., and there will be corrosion.

Are those inspection panels?? Also, if rivets were set over the blue protective film, I would imagine they will need drilled out and removed too. For reasons stated above.

I don't think it would pass the DAR's inspection, Don. If it was me, I'd remove it ... probably after a few choice words and a beer or two.

Argh! I did the same thing somewhere between the 8th and 10th bays in my left -10 wing. Only on the forward side of the spar. I'm in a little better situation (I cut/melted away all the plastic where the ribs and skin meet, then primed all mating surfaces), but still too deep for me to reach in and peel off. I can get close from the tip, and close from the pitot inspection plate, but just not close enough. I will have to put in a extra inspection plate in order to remove the plastic inside my wing. Must have been one of those late night builds.

Off the topic a bit, but that looks like a humoungous inspection cover in the curved portion of the wingtip. What would that be for? Just curious.

There is a need to get in to install the filler cap and connect the two tanks, and run tank vent line back to the fuselage. Looks kinda like this when complete (with the wing upside down):

Yeah that was my opinion as well. Just thought maybe someone had a brilliant idea to avoid all that work!
