Duty of Care
Interesting contrast here between the response of the USN and the UK MoD to a known flight safety-critical structural concern on one of its airframes. USN - scientifically work out all those airframes that could be at risk and ground them for repair. MoD - employ expensive contractors to carry out a risk analysis and then continue ops unabated, with 'all is ok here' press releases after 1 fatal and several near-disastrous incidents.
