Passengers would be more confident in the fixes if the huge effort AH has put into analyzing these accidents had allowed them to reproduce the MGB failures that occurred. Without that, concern remains that the fixes are not addressing the problem.
I don't know if the other crashed aircraft had the same bearings, but in case it had, then this is taken care of by removing these bearings from service, as the other ones never had an issue. Additional safety on the MGBs that never had an issue in the first place, is then subsequently provided by increasing inspections, reducing lifetime and better chip detectors. This should take care of the problem... again, 100% guarantee? No. But if you want 100% one should just stay where humans belong: with 2 feet on the ground...
