| Subject: | Cracks Around Rudder Stiffeners... |
After washing the 'ol RV-8 last night, I noticed that there is about a .5" crack
in the .02" skin of the rudder in the *front* of two of the angle stiffeners
(towards the leading edge of the rudder). The skin is a little "bulgy" right
there, and its possible that I gave that area a good push with my thumb at some
point to see if I could get it to flatten out.
Obviously I need to keep an eye on this, but is it anything to worry about, really?
I'm just about ready to take the plane in for paint, so if I have to do
something about it, I'd rather do it *before* the paint.
Thanks in advance for the feedback,

Any listers planning on attending the WCFC this weekend in Madera California?
I'm planning on being there with the 'ol RV-8. Come up and say 'hi' and introduce
yourself; I'd love to meet some of the Listers in person!

I'd rebuild it before paint - my .016 rudder skin had a hangar bump which I
covered with microballoons. It got a second bump and I rebuilt it with a
.020 skin - I have on IO360B1F6 so it was recommended anyway.
No regrets and it was a weekend job...the first part I built and the last
part I built.

I also have some cracks on my 6A rudder. Cracks are on the first rivets of
the stiffeners. Next to the area where the skin is not supported be either
the stiffener or the leading edge spar of the rudder. It appears the skin is
allowed to flex a bit because the stiffeners are not attached to the spar. I
stop drilled each crack when I first discovered them and they have not
progress further in 5 years. It is on my walk around check list and I look
at them every time I fly.
NOTE when I first found the cracks, I called Van's ....before I completed
the explanation of my problem I was stopped by the 'friendly' tech help guy
who said "you must have a big engine on your 6A don't you" I admitted I have
an O-360 with high compression pistons, electronic ignition and constant
speed prop. His next statement "there is your problem!"
I suggest you stop drill the cracks and watch them. If you build a new
rudder before you paint, with no change in the rudder design, you will
probably experience cracks again.
