Nobody is arguing that your likelihood of dying is significantly higher on a private flight.
I might be wrong, but this is indeed what I am arguing, and I think 'jacquesm' is saying the same. 'nostromo' says your likelihood of dying is the roughly the same for both private and commercial flights, and I don't think this is true if the metric is getting from point A to point B without dying.
If my memory of previous research is correct, a passenger on a private plane has approximately the same risk per mile travelled as a passenger on a motorcycle[1], which is something much greater than the risk per passenger mile of a normal automobile, which is in turn something significantly riskier than traveling the same number of miles by a commercial jet.[2]
We're arguing that the thing you should care about is whether the specific flight that you are on will crash, which has a significantly higher likelihood in general aviation.
Yes, each flight you take in a private plane is significantly more likely to end in a crash than each flight you take on a commercial airline. Your chances of being killed if the plane is involved in an accident are greater in a private plane (fatalities per accident are greater on the commercial flight, but risk to each passenger is lower). Therefore, your chances of dying per flight taken are greater in private flight than in commercial aviation. Is this the same as what you are saying?
[1] Edit: Found a seeming good source at http://www.nianet.org/ODM/presentations/Overview%20SVO%20Ken..., page 8. Looks like I was slightly wrong to say that motorcycles and GA are comparable risks. If we trust their estimates, motorcycles are about 2x more dangerous per hour than GA, and 3x more dangerous per mile.
