struggling with self-intersecting T-Spline design

[sharscott2]

Lofting this airfoil in different segments (to merge into a single body) has presented a problem I am at a loss to solve. The trailing edge of the lofted body has the T-Spline self-intersection error which prevents me from finishing the form and converting to BRep body. I have looked at this in Box mode (but can't figure out how to manipulate the trailing edge without distorting it). I have tried Repair,  and Make Uniform. As near as I can tell, I have to flatten the trailing edge to eliminate the self-intersection error but I can't locate a tool that works. I have read a dozen articles and watched youtube videos about this error but I can't find a path forward.

best to post your file in the original thread instead (this one) of starting a new one to post it.  

in the model the posted in the other thread,  the edges at the trailing edge need to be merged.  use the merge tool under the modify menu and then crease the resulting edge.
