Can ailerons control a broken cable on 1/3 flaps?

Nope, see above. It doesn't have to be designed that way, but on most GA aircraft it will naturally be that way as part of the average design that makes the ailerons typically not less than 1/2 the flap span. I imagine as you get into more complex systems like the DHC-7 (very large flaps, small ailerons) or the MU-2 (no ailerons at all) that you may get into uncontrollable conditions with an asymmetric flap deployment.
