I looked back at my HS and found that the distance was real close to
in-tolerance...And agree that the area in concern is plenty Fastened
down and should be just fine.
If you want call Vans' and check. Also If you did have to Flute a bunch
I would shorten up that piece a bit.

skinquestion, caution re: 405/404 nose rib/710 s
Joe,
Had the same problem. Realigned, adjusted, adjusted, adjusted finally
just drilled it and didn't worry about it. Yeah, the rivet is close to
the edge but it won't make a difference due the redundancy of fasteners
in the area. I called Van's, they said the same. Just watch those -9 g
outside maneuvers when your flying it! Build on my friend!

In assembling the subject topic it appears that drilling the prepunched
601pp hole thru 601PP/702/405 will violate the edge distance on HS405
(the
forward part of 405 slides under the flange on the 702 forward spar and
the
601pp skin is used as a drill guide.) The violation appears to be
slight,
maybe as much as a 1/16 but it is hard to tell without actually drilling
the hole and measuring (405 is the bottom layer of the three being
drilled
at this hole). I haven't drilled the hole to find out.
Is this in the category of don't worry about it, it is one rivet or is
the
405 rib shorter than it should be? I tried taking out some of the flutes
to
lengthen the flange but didn't appreciably affect it. The only solution
I
see is that the portion of the 405 flange sliding under the 702 flange
must
be longer to avoid the problem.
For what it's worth:
The instructions warn that when drilling the forward flange of HS405 to
be
careful of hole location (i.e. top hole is not centered on HS710
stiffener
but is displaced downward to maintain 405 edge distance). What the
instructions don't warn about is exercising care to maintain edge
distances
on the other holes i.e. the center holes in 405 go through the HS404
nose
rib aft flange when drilling the 405/702/404 holes. If you drill the
HS405
holes where the measuresments on the plans state you will have
violations on
the 404 nose rib. I moved the holes inboard on HS405 to move the
resulting
holes on the aft flange of 404 inboard as a fix. Maybe this is a don't
worry about it issue as well but one of the problems of being a new
builder
is not knowing which rules are sacred and which ones can occasionally be
bent.....

Joe

Jeff,
Thanks, it is reassuring to know I wasn't the only one and that Van's is in
agreement with the "solution"
Regards,
Joe
