Anyone taken a Horizontal Stabilizer apart for cleaning light corrosion?
I have three and they all seem to have some level of corrosion inside.
Any tips and tricks about getting it apart and back together?

I did it many years ago. Mine had some damage to the spar, so I had to replace the spar. Once the skins are drilled off the spar, there's lots of access to get the screws out and back in. I used NAS 1801 screws and extensions taped together to reach down in the horizontal to tighten them back up. Squeezing those -5 rivets holding the skins to the spar near the center was the hardest part. Ended up removing the rib halves from the skins and priming under them, too.
