The A series are just as prone.
If you think about it most of the small aero engines are Continentals. Small engine, burns less fuel, has a smaller carb throat and smaller induction manifold. Smaller air passages mean less ice is needed to cause a problem. Burning less fuel they produce less heat. The larger Lyco's tend to have a sump rather than a separate oil tank with the inlet manifold pipes running in channels cast into the sump to help keep them warm. Small Continental tend to have everything hanging out in the breeze. QED
This is simply a response to the comments above and nothing to do with this tragic accident.
