(RV6 Flyer) ________________________________ Message 1 _____________________________________ Time: 03:12:20 PM PST US From: Matt Dralle Subject: RV-List: 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.

Capen" Subject: Re: RV-List: Cracks Around Rudder Stiffeners... 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. ----- Original Message ----- From: "Matt Dralle" Sent: Thursday, April 28, 2011 6:04 PM Subject: RV-List: 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).

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.
