Actually, the good news is we try to invest a lot in prevention. When we do investigations, somewhere we have failed prevention. Prevention, as you know, is a very tough job.
So the number is going down. I'm going around showing the stats right now, and we have fewer accidents than we had in the last 10 years. So we're doing better through prevention, through better airworthiness, and possibly through a better investigation process and sharing all that information. We have a system in which each one of those occurrences is reported. Everybody in Canada can access it and see what happened there—what they have done and the lessons learned. We use that and hammer down the thing. It's all about sharing information.
I must put a caveat in that contrary to the TSB.... the TSB doesn't investigate everything. They investigate no major accident, which would be in the best interests of the public and so on. We investigate everything. Somebody installed a wrong bolt to something somewhere and someone cut that, they would come forward and say that during the inspection for the pre-flight this morning, they realized that was not the right bolt there. All right, fine, we enter it, this is an occurrence.
We have a network of more or less 330 investigators. They all report to me for investigation purposes only. Some have different qualifications, but those types—you know, like investigating why this bolt was there instead of that bolt—that would be done locally. They would follow the process, they would report to us, and so on, just to explain.
As I said, there are four classes of investigation. Most of those 3,300 things are little stuff like that, or a pilot that did not sign the proper documentation before going flying, and that type of thing. That's what I mean by we invest a lot in prevention. Those could have led to an accident, but never had an accident. But for us there was a possibility, so we investigated.
