A few years ago I calculated with a friend the accident rate of several cohorts of Brazilian aviation (well, the part of aviation that operates on aerodromes, so no agriculture or sports). Our worst cohort was for private planes, private pilots, on small airports, on fast growing cities. It was just a little bit under 4*10^-6 accidents (all, not only fatal) per airport operation (that is, twice your number).
I was really scared by your number. I wouldn't ever jump into a random private plane, and seems that people refusing to jump into a B733 Max (looks like I wrote it wrong earlier) are doing a reasonable thing.
For long distance trips where they have an option? I'd guess that many don't.
Still that 4e-6 per trip number is worse than the city driving statistics I've found. And that 8e-6 per trip (4 per airport operation) is around the motorcycle values.
