Let me back up and start with the beginning of your question.
The mandate Parliament has given us is to investigate accidents. So when there is an accident and we think there is something we can learn, those are the accidents we investigate. We try to find out what happened and why it happened and then we look at the underlying safety deficiencies. When we look at the underlying safety deficiencies, that allows us to determine whether there are problems in the system. If we determine there are problems we communicate those.
With respect to the Cessna 208, yes, there were some previous accidents, but we learned much more on the Pelee Island accident than we ever knew before, and on the Morningstar we learned even more, because on the Morningstar investigation we believed we had an aircraft that took off clean and encountered icing conditions. That allowed us to learn an awful lot more about the performance of the aircraft in those conditions, and that is why we made interim recommendations on the Morningstar.
