Inspect the rib carefully in comparison with the other outboard rib. Use
calipers if needed to measure flange width & hole position. Does
everything match if they are placed back to back? Look at the tooling
holes in the web of the rib. Any evidence of them being deformed?
I had a problem with holes in several main ribs in the wing not lining
up with the wing & discovered that they had not been seated properly on
the tooling pins before the flanges were pressed. The flanges were
*slightly* different widths & the tooling holes were elongated slightly
where the tooling pins tried to punch their own holes. Of course, when I
called Van's, this had never happened before & probably wasn't happening
to me either. (The new rib they shipped didn't have the distorted
tooling holes & all the prepunched holes lined up perfectly with spar &
skins.)

Hi Charlie,
I have heard this before. There's a guy here in Northern Ireland who said he
same problem with RV7. He called Van's and they send out replacement.
Incidently his is one of the first batch of 100 that had the narrow rudder.

I had a couple of emails with the Van's folks. they agree that the issue is a
mis-bend elevator skin. They cheerfully offered to send a new one. Always good
support, in my experience.
Thanks for everyone's input on this.

Hi,
I'm trying to get my brother in law to OSH on Friday afternoon from the
Minneapolis area. No problem pitching in on expenses. He won't need a ride
back. If you might be able to offer up a seat, let me know by email at
russ@wernerworld.com and I'll arrange a contact.
Thanks,
Russ Werner
