if you’ve scratched that itch enough flying helicopters, now is the time to switch to the airlines.

Some people need to swot up on the raw numbers of rotorcraft accidents, and deaths.

Two types with a substantial period in service (14 yrs), shine out above all that has gone before in terms of the raw numbers concerning accidents and fatalities. These are the S-92 and EC225. Maybe the 7 and 8 tonne newbies will match and exceed the standards set by the 92 and 225 (let's hope they do), but that remains to be proven. Other comparable aircraft have had hundreds of accidents including hundreds of fatalities. In particular, doing 12 years of intense CAT service without a fatality is pretty outstanding.

The numbers are out there.

Is there a link to the numbers that you can share?

ASN is a really good starting point. Clearly, through the manner of how this site operates, rather like Wikipedia, one needs to be sceptical and look for corroboration in news articles and regulators' websites. The thing about the 225 and 92 is that so little has happened to these types that it is relatively easy to join up all the dots.

It's a while ago now so I don't remember all the details of where and how, but in 2013 I set about trying to get some perspective on this. ASN wasa major part of that. Once you start looking back at things like S-61, 330, Mi-8, and 332 accidents, the numbers stack up in a way that is no longer happening with modern types. Take the Mi-8/17, which have been produced in very large numbers compared to most types. The number of accidents is large, though not very large in relation to the number built, but when you get to many thousands of fatalities and then can't keep count, it's quite chilling, and the contrast with modern types could not be greater.

From what I can tell of the figures from the North Sea the numbers for helicopter safety the numbers are far from encouraging ...
  • In the first five years of NS ops there were 18 helicopter related fatalities
  • In the most recent five year period there were also 18 helicopter related fatalities
  • The safest period of operation 1987-1996 had not a single fatality despite this being the period of peak activity.
  • In the first 20 years (1975 - 1995) there were around 76 helicopter related fatalities over four accidents
  • In the last 20 years (1997-2018) there have been around 62 helicopter related fatalities over ten accidents
So in what way are things safer?

Also we need to debunk the myth that most accidents are pilot related. Of course, in aviation in general that is true. But in the NS the vast majority of these 144 deaths were attributed as having a primary mechanical cause.

So why has the Puma been singled out;
  • It's the most common type so unsurprisingly has been involved in more incidents
  • The workers and unions have lost confidence as the accident rate increased
  • AH have failed to win them over
  • The Puma is an older design which is smaller and arguably less comfortable than the new machine (S92)
  • Despite a nasty scare the S92 has yet to have a fatal accident in the North Sea
  • The specific causes of the epicyclic related accidents is similar but remains unattributed awaiting the final report - so doubts remain

Slight correction, there were fatalities in the period 1987 to 1996, Cormorant Alpha 1992, Brent Spar 1991, to name a couple of fatal accidents.
