I agree that is the basic difficulty here and unless the reason can be established and the problem definitively resolved it will be close to impossible to get this back in the NS O&G sector. Even then the damage may already have been done.
I understand the sentiment, but what if the next rotor to detach is the other brand of gearbox with a TTIS of 35hrs?
They have taken steps they think
might mitigate the likelihood of a reoccurrence, but if they don't know why it happened, they can't know if their recommendations will have any mitigating effect whatsoever.
