Rotary accident stats
 

Hi guys,

I am working on a new air access project where we want to compare accident rates across a/c types, and especially compare fixed vs rotary wing turbine a/c.

My previous "go to" source was Robert E. Breiling Associates, Inc., which compiled a range of helpful accident stats. However, the phone number on his website was dead, I then Googled his name and - sadly - I discovered that he died in 2018 - albeit having had a good innings at 88.

Does anyone have a copy of his "2015 Turbine Helicopter Review (Single & Twin Turbine Heli.)" that they can share? I can see the price still showing on his website is $200, I will donate this sum to the charity of choice of anyone who can send me a copy!

Cheers,
KP

**Oh dear, I gave this thread a stupid name & realise I can't change it using "edit" - should have been "Rotary accident stats"!

Fixed: Splot

IOGP and HeliOffshore publish data, as do EASA and the FAA

Unless these stats include details on both type of flying and type of pilot coupled with the numbers of aircraft in the fleet, these reports are a mathematical “fools errand”. For helicopters, both the most inexpensive helicopter and the one used in the most dangerous mission will appear at top of accident lists (so R22 and MD500), however this doesn’t conclude that either of these are inherently dangerous aircraft nor less safe than competitor aircraft.

Serious stats are normalised to account for these variations. If there are 100 R22 accidents per year it means nothing, as you suggest, but if there are 2 R22 accidents per 100,000 flying hours, or 50,000 landings, that's is a more useful metric. (Made up numbers of course, before somebody gets on the outrage bus and asks where I got my figures from......)

Call me old fashioned but, maybe do the work you're being paid for yourself....

That is what he is doing by exploring all avenues, including no longer published data.
Further, the value of the community is usefull to understand the state of the industry from the bottom up, instead of from the top down like these aggregated report probably suggest.

Would be really interesting to see the outcome but as per my understanding it matters who flies ( military?) it and where he flies....( Hot, dusty and humid)..... looking forward to you can bring up from stats
Good Luck
