We can see that already by the data given on the cirrius site.
Its just that they decided to remove the instructional and commercial GA flights out of the data so that it looks as if the accident rate is below the average.
The fact that those flights in general are operated in the risker phases of flight for longer ie takeoff and approach/landing should mean that they have a higher risk so therefore higher chance of fatalities. But that's not shown out. They have to remove them to make the numbers look good. I might add all the agricultural crop spraying and the like will be in there as well which is even higher risk again.
In general the training fleets are 20-40 years old with some new machines thrown in. And the commercials will be slightly younger but the majority of them will be more than 10 years old.
