Once the bears stop boarding there is nothing the oil companies nor operators can do.
As a pilot I would be very reluctant to go out and operate a machine with a proven deficiency as long as there are no clear and decisive steps taken to mitigate the risk. I would want proof that my MGB is not about to thrash itself to bits, not just a general assurance that with a bit more monitoring it will be ok. That did not work last time either.
And I speak from personal experience of my type being grounded after a fatal accident caused by technical failure. The first few flights after we were cleared to operate again where still quite scary and all of us were extremely vigilant.
