This is not a silly topic, it has caused many deaths, the problem is not only associated with smaller pitson aircraft.
A number of inidents come to mind that were a result of icing, I understand that ATR have had a number of stall spin fatal accidents in the states.
As a result of this they test flew some ATRs behind a modified C130 that would spray water to aircraft to build up ice to see the effect of it on the aircraft. I understand they improved the de-ice capabilities of the aircarft after this.
The MU-2 also had a nasty habbit of icing up it underside whilst on night freight. The autopilot would keep trimming back to maintain altitude until it reached it limit, disconnect and kill the pilot. The MU-2 does not have ailerons, it used spoilers for lateral control.
I think the Australian ATSB is about to release today (announced on the SAAB web site) a report of an investigation into a SAAB 340 that was holding near Melbourne, whilst in the holding pattern ice built up, it went into an inverted spin, the guys got the aircraft out (just) and landed ....nice work.
Aircraft certified for flight into icing conditions normally have a big notice in the flight manual,
not certified for flight into severe icing conditions. On turboprops its normally goverened by ice build up on the spinner, windscreen, of ice build up in exceess of the cycle of the de-ice boots.
