Nobody can really tell just by looking at the picture. I would want a
look at the aileron attach points and control linkages - but that would
be a flashlight-and-mirror deal. If they were OK, I would cheerfully
sign the ferry premit and fly it.

The damage to the aileron is superficial. Stay in the green arc and it
will be OK. Do I know that beyond a shadow of a doubt? No. But as an
A&P and engineer, I consider it so close to certainty that I would be
willing to take the risk.
