I'm a little skeptical about the numbers. The Bureau of Labor Statistics claims there were 109 fatalities among pilots, 22 airline pilot fatalities and 87 commercial pilot fatalities.
I took a look at the NTSB database and here's what I found.
Part 121 fatal accidents in 2004, 2, with 3 fatalities
Part 129 (foreign carriers) fatal accidents in 2004; 0
that's not quite 22 dead airline pilots.
here's the rest:
Part 135: 21 fatal accidents
Part 133 (rotorcraft external load) 3 fatal accidents
part 137 (ag ops) 7 fatal accidents
part 125 1 fatal accidents.
that's 34 fatal accidents, those accidents had 22 pilot fatalities.
That's 36 fatalities in 121,125,129,133,135 and 137 operations.
That would mean that ther were 73 pilot fatalities in flight instruction, aerial photography, wildlife surveys, firefighting, corporate aviation and other commercial GA activities. Personally, I'm a little skeptical, particularly in light of how far off thier numbers are for airline pilot fatalities.
As a side note, only 3 of those fatal accidents (2 pilot fatalities) were in Alaska, so that doesn't have a very large effect on the national numbers.
