Broken Wing Gambit on AoO

[Kifaru]

Pretty much, that's it.

Can you use Broken Wing Gambit on an AoO? Broken Wing requires a free action and I know that in most cases free actions are not allowed outside of your turn. I also know there are some exceptions. This appears to be a case that may warrant such an exception.

I don't think so, there isn't any special clause saying that you can take the free action outside of the normal window (your turn).
