Anecdotally, from checking the AAIB reports each month, I'd say there is at least 10 fixed wing incidents to one rotary. Often more. I'm also completely ignoring the type of flight part, as well. (Private/Commercial, etc.)
However, it might be useful to look at it as a ratio of of registered aircraft types. I'd guess that the ratio of incidents rotary to fixed wing, is pretty similar to the ratio of registered craft.
With regard to that, on the UK register, at 1st Jan:
Fixed Wing: 10099
(10099 + 4045=14144)
(This ignores Airships, Balloons, Gliders, and various other "niche" classifications)
So 1260/14144 is around 9%, or very approximately, rotary:fixed = 1:10.
I dare say statistics for type and number of flights would be pretty tricky to find. Wonder if they even exist anywhere? _________________ J.
Thanks for that James.
What I was trying to work out was: is rotary flight is more dangerous than fixed wing but perhaps your posts suggest that pro rata there is probably a similar amount of accidents in both.
And maybe a post for another day but.............is the R22 as accident prone as many 'pilots' on another forum make out or, once again, is it just that we hear of more on that type as there are more of them around?
Yes, there are more around...*** but by its cost effective nature, it's a machine which is often selected to operate in a training environment.
*** Actually, no there aren't. G-INFO stats below show more R44 on UK register than R22. And globally, Robinson have produced more R44 than R22. So it might seem like more, but I'm wrong! It's just not true!
I don't know that all that many accidents occur in R22 whilst in training, but pilots training on it, will often go on to self-fly hire, or own an R22. You then have a whole load of low houred and relatively inexperienced pilots flying them...!
I guess you'd need to compare numbers to how many on the register - a quick search on G-INFO shows R22 registrations currently at 161 (and including de-registered craft, 412).. actually, let's put this into a bit of a table for some of the most reported types:
Registrations Incident Ratio
Type Incidents Current inc. De-Reg % Current % De-reg
R22 101 161 412 62.7% 24.5%
R44 47 251 316 18.7% 14.8%
B206 28 116 506 24.1% 5.5%
AS332 23 28 62 82.1% 37.0%
H269 22 42 137 52.3% 16.0%
AS355 15 60 167 25.0% 9.0%
This isn't particularly scientific (and I'm not entirely sure I've found all the aircraft of certain types on GINFO - JetRangers are variously Agusta Bell, Bell, 206B, 206A, etc...). Also it's a cumulative number of incidents between '97 and '10. Perhaps incidents per year per type, against number of registered craft for that year would be more accurate? But really, I think the numbers probably give a reasonable illustration of 'type' safety.
What it does lead me to think, is that you could probably 'spin' the numbers anyway you wanted, with sufficient data. What about accident rates per flying hour? (Wildly different flight hours between a busy flight school's R22 and a privately owned R44!)
Looks like the SuperPuma is more accident prone than an R22...!
Have a look around veeany's helicopter safety site for various different (statistical) views of UK incidents. _________________ J.
