Well, if one get hit so that aileron or flap won't work any more does it mean that that part is surgically removed? Of course not, there should be a lot of twisted metal, maybe remaining part sticking whatever direction. Even a lot used airframe can cause as much as 50km/h reduction for top speed (due to wing deformation that aluminium suffer).
Also, a lot of books say gear falling to down position after hit.
So, wtg if that is the case.
However if it's only an 190 issue, then it needs fixing.
