remember this is a RUMOUR network!
so we are probably not getting anything like the full story. No doubt FH are on top of it, the appropriate specialists (none of whom are on this forum) will have the full picture
UK are still flying and I don't believe that any other EH101/AW101 are grounded so this suggests not a fleetwide/design problem
At some point all will be made clear I am sure
anyway congrats to the pilot for getting safely down
