Mark_ Posted April 5, 2009 Author Report Share Posted April 5, 2009 Those are indeed interesting stats and they show that Robinson helicopters had far more accidents in the UK than others. Does that mean they are less safe, or is it because there are far more of them and that they are being flown by less experienced pilots?

Elvis Posted April 5, 2009 Report Share Posted April 5, 2009 Looking at the NTSB reports most of the R22 accidents are training related. Quote Link to comment Share on other sites More sharing options...

Petit-Lion Posted April 6, 2009 Report Share Posted April 6, 2009 Some interesting stats. http://www.helicoptersafety.org/acManufacturer.asp Interesting... to show how unprocessed data can be pointless. So I played a little with figures in a totally irrational way, just for fun. Of the total, 10.5% of accidents are fatal (38/361) Bell: 22.5% (7/31) Eurocopter : 12.7% (9/71) Robinson: 9.5% (13/137) So when an accident occurs, Robinsons are more likely to save lifes? Of course not. Westlands are, but I arbitrarily choosed to only consider the three biggest makers. I know, these computations are stupid, but that was the best I could do with just these data... keeping in mind that number of fatal accidents is NOT number of fatalities. Would be more interesting with the numbers of aircrafts in service in UK... better, the number of commercial and private aircrafts (numerous private helicopters in UK, i.e. numerous R44s). The number of commercial aircrafts doing high risk jobs: training? slinging? And, of course, the number of hours flown (very low for private aircrafts). Training accidents were mentionned. Too bad that the R22 is by far the most popular trainer. Not the best, I know. The Bell 206 is the best trainer. Mind to play stupidly with airliner stats? I bet that the highest fatalities involve Boeing and Airbus. No passenger died in a Constellation last year: this is for sure the safest airliner. And the Concorde safety record is still better than that of the Space Shuttle Quote Link to comment Share on other sites More sharing options...

Mark_ Posted April 6, 2009 Author Report Share Posted April 6, 2009 as PL pointed out, straight stats can be useless. However, here is a searchable database of helicopter incidents in Canada. http://www.cbc.ca/news/interactives/helico...base/index.html Quote Link to comment Share on other sites More sharing options...
widgeon Posted April 6, 2009 Report Share Posted April 6, 2009 as PL pointed out, straight stats can be useless. However, here is a searchable database of helicopter incidents in Canada. http://www.cbc.ca/news/interactives/helico...base/index.html http://www.griffin-helicopters.co.uk/accidents.asp here is one of the better ones I have found for most world accidents. if you had the time G-info.uk gived the last reported hrs for helicopters on the register , you could use that to make some pretty good assumptions about annual hrs . http://www.rotor.com/portals/12/Statistics...201997-2006.xls HAI also have come good reports though not by model Quote Link to comment Share on other sites More sharing options...
widgeon Posted April 6, 2009 Report Share Posted April 6, 2009 Run a query on Griffen database for R22 and R44. Is shows 13.5% of r22 accidents fatal and 29.5% of R44 . Quote Link to comment Share on other sites More sharing options...
