Range of Motion for Aileron Bellcrank

[bob865]

Good Morning. I'm working on the internal of the left wing including the aileron bellcrank and pitot tube air lines and heating wiring. I fabricated a bracket to hold the pitot tube and heating wiring at the bellcrank so it can't inadvertently touch the bellcrank during flight. It looks and works great, but it impedes motion on the outboard most extreme motion. I believe it is outside of the normal range of motion because it's at the point where the aileron pushrod would start pulling again, but I can't find anything to say yes or no, so I wanted to ask the collective mind of VAF to see if you can confirm my thoughts. The attached pictures show the bell crank at the limit of motion due to the bracket I fabricated. Is this outside of the normal range of motion?

Thanks!

Personally, I would remove the bracket and try something else. The bracket under the bell crank changes the geometry ever so slight.

Mount and connect the aileron, then measure motion. The travel spec is in the instructions.

I tend to agree... an over/under routing is less clean than OP's version, but easier to keep things separated:

That bracket routing would interfere with autopilot servo mounting if in the same wing. Moving wires & plumbing either above or below the bellcrank would be better.
Also, Do you have the bellcrank positioning tool? (W-730 I think, don’t have the plans handy) Triangular shaped piece, it will show you where bellcrank is in neutral position, range of motion would be about 20 degrees each direction from there (confirm with plans!)
