If MGB design/production is to be blamed (again) than NH90 MGB
/ with civil cert. may be considered like one of quick patch up solution...
NH90 fleet have reached 100.000 f/h without known MGB issues.
Regarding HUMS that is for sure way to prevent or reduce such kind
of major structural failure but producers and operators must open the
data access to rest of the industry. Today's single board computers are
powerful enough to perform near real time computing and indication
of something major is about to go wrong.
RIP to all poor souls and sincere condolences to all involved.
