| Subject: | Wing skin oil-canning |
I just finished riveting on the top LH wing skins and I noticed one of
the
"squares" was indented and would "oil can" when pushed from the inside.
The square is bounded by two ribs (the fourth and fifth from the tip),
the
forward spar, and the "J"stringer. It is the fourth bay inboard from
the
tip (RV-9). All other skin "squares" are tight/neutral. Any ideas
(other
than drilling out every rivet in the skin) to address this issue? I was
thinking of drilling out the rivets around the square to allow the skin
to
average out between three squares and re-rivet. Just wanted to see if
anyone else has run into this problem and worked out a solution. Other
than this the skin is perfect (well, pretty good at least). Thanks in
advance for the help!

Don't worry about it. If it doesn't move more than
1/8 inch you don't need to worry. Mine does that and
after 300 hours it's OK.

Don't worry about it. A lot of metal planes have oil canning in them,
the wing panels upper and lower or the fuselage, and all control
surfaces. Move on and continue building. You will only make a big mess
if you try to get rid of it.
