This might be the problem >
Not sure that this may be part of your issue.
I posted in the Plan "Gotchas" on 1/20/2015, it's on Page 4, titled:
"Gotcha 08-02, Rear Spar
Attached is a better description of the Plan Gotcha; RV14, Empennage, pg 08-02, Rev 0, 4/15/13. . . . "
More description follows in the posting including a diagram; regarding attaching the HS-906 to the HS-00903-1. If your problem is with the alignment of the ribs where they attach to the rear spar at the doubler plate, this may be your problem.
