Flyer43,
"talking with the benefit of hindsight" You are missing my point. The point is that BECAUSE the cause was still unknown, people were talking unknown riscs in operating the A/C when it could very well have been a problem common to more S76s but just happened to rear its ugly head on VX. I was taught to assume the worst and cater for that in order not to get caught out.
I'm still not convinced that the type should not have been grounded until proven safe simply for commercial reasons. There are lots of reasons for not flying that are happily accepted because the riscs are obvious, e.g. icing, fog etc. On those occasions the clients will have to make different arrangements, so they could have made them in this case as well.
Again, I stress the fact that I am not bashing anyone, I just want to learn from this discussion. If we learn from this tragedy we may be able to prevent another.
And I DO intend to fly it as soon as it's cleared.
