[NSRCA-discussion] Wing tube phenolic repair "help"

Fri Aug 11 05:33:45 AKDT 2006

Actually, this is my back up / soon to be primary plane. I was getting ready for the maiden this weekend when I noticed it was a little loose. My Epicure II is ready to go!

  Going to try to make Quincy, have to clear it with the boss first.
