The average death rate for motorcycles and general aviation is around 1 death per 100,000 hours. Just an average, as you observe.
BTW, flying a small plane costs maybe $40/hour in fuel, but if your life is worth $12.5M (the statistical value of a human life these days) then the cost of the risk is $125/hour, three times as much. This tells me it's likely a good idea to include an emergency whole-plane parachute system on general aviation aircraft, even at the cost of fuel efficiency.
