Fatality stats are an issue but failure rates are more important. The failure of an engine will leave the PIC to manage the situation all the way down to the ground and will tax their ability. It would be unfair to hand an inexperienced PIC a situation that may be beyond their capability, even with the best crashcage in the business.
Not all Jabiru engines power Jabiru airframes, not all Jabiru engines are piloted by PICs with high hours and extensive training, not all Jabiru engines fail in a perfect place (some might even fail at the end of a strip adjacent to a 12 lane expressway with a hospital and high school and a beach at the end. Not all Jabiru engines are maintained by experts (some Jabiru engines are maintained by people who are not fit to put petrol in the tanks).
The most useful statistic to me, BEFORE any other is quoted, is the FAILURE RATE PER HOUR or the FAILURE RATE PER MOVEMENT (both subject to fudgeing). Deaths only matter when you want to examine Airframe, competency, environmental and other issues which com into play, almost, independently to engine failure.
It would, therefore, be kind of you if you redid your stats based on engine failures alone (running out of petrol is not a failure, running out of oil is but not if the PIC forgot to check)
