"Roll it up you're gonna die"
I tried to find some data to back this up but it seems that the manufacturers aren't too keen on advertising stuff like this...
So I did a *very* rough estimate using the NTSC database: 17% of Bell accidents had one or more fatalities, 25% of Eurocopter/Aerospatiale accidents had one or more fatalities. Figuring that mission could sway the results I did a type specific search for two helos with similar missions: AS350 vs 206 - that yielded 27% for AS350 and 21% for the 206.
I know it's a really crappy way to estimate fatal accidents but the trend is there.
BTW, yes I am bored & sitting at home wishing I was flying!
