From what do you get demographic? Anyway, my crude method: FAA
registration records indicate the vast majority of the approx. 1,000
are corporate-owned, and many names suggest more than just holding
companies. That suggests significant % are business use, and many of
those owned by holding co's may be substantially biz too. The latest
Nall Report cites biz use as about 4 times safer than GA as a whole,
which tends to suggest the accident rate may be on the high side. The
average age of the fleet is about 2 yrs, so several hundred thousand
hours could be a bit high, and with 18 U.S. accidents, the rate thus
appears typical only for GA as a whole.
