There have been accidents in that 6 million hours though, including Shell's last fatalities in UK and US.
I suspect the last US incident you refer to was as a result of a cause not within the boundaries of the OEM to control, so hardly the OEM or platform to blame and as for the UK incident, would that not be down to human and/or maintenance error and not certification or type?
In spite of the very latest and greatest safety and certification standards, Rotorheads records numerous AW139 sorties that ended in tragedy – or very nearly so - with only a fraction of the S-76's fleet hours, so I’m not so sure that pedestal you preach from has sure footings.
