RV-12 Tailcone J-Stiffeners

[Wolfgang M.]

I started to assemble the tailcone. Page 10-06 Step 4.
Unfortunately the J-Stiffeners F-1283A & B do not fit at all. It is almost one hole diameter off.
Does anybody have an idea what could be wrong?

Could you post an image of that part please?
I remember that every time something hasn't fit or seemed ackward, it was always me who overlooked or misaligned a part.
I would be suprised if in your case the J-stiffeners of the skins don't fit in.

Go back and retrace all steps leading up to that step. It's conceivable a part could be wrong, but highly unlikely.

[Wolfgang M.]

Thank you for your reply.
I tried to send some Images, not sure how it works!

I am not in my shop right now so I can't answer 100%,
but to me it looks that the F-1283A stiffener should be placed outside of the J-channel of the skin.
In your picture it is located inside the J-channel.

[Wolfgang M.]

The F-1283A stiffener has to be placed inside of the J-channel of the Skin.

In the meantime I received some information from Vans. They are back from Oshkosh now.
This Problem is caused by a mis bent part and happened a few times recently.
It will be a quick and easy Job to fix.

I recall marking several sections that did not appear to line up and I was concerned. Once everything was cleco'd up it all lined up.

I do have some ripples over the stiffeners - common as I understand it. Vans said build it and fly it... so I will.

Wolfgang, I came across the same problem with the holes not aligning when the stiffeners are placed in the J-channel of the bottom skin. (Empennage kit shipped Jan 2014)

What was the information from Van?s and the fix?

Hi Scorkey... you're asking a question in a 4 year old post.
I'm building the tail cone of an RV-12is right now and I have not had any alignment problems with stiffeners.

If you can be more specific... what part is not aligning with what part... I'll try to help you.
