S76Heavy
"I'm a bit confused about the issue of when to ground a type, but if it's a main blade spar, it seems generic enough for me."
Now you are talking with hindsight. Your original statement referred to grounding the S76 when absolutely nothing was known about the possible cause of the accident.
Let's see what the press release says and hope that common sense will prevail thereafter.
I'm a pilot as well and would also like to know that I can confidently expect to be home after work each day!! Provided that suitable rectification and/or control measures are put in place by the right people, I would be happy to fly in any S76 again.
