Airbus encountered a small problem with the 225 and yet it still is operated in a few countries.
The 350 has non-crashworthy fuel cells as does the Robbie and they continue to operate.
Do not think for a second the "authorities" care to permanently ground any aircraft that was properly "certified" in the past.
The FAA did ground the Robbie over some blade delaminations and also required special training for the R-22 which some 16,000+ pilots have undergone since the FAA Ruling.
