Would have saved a number of Lives and them an economic disaster.
Agreed, but again we seem to be relying on HUMS as an airworthiness assurance tool, rather than the reliability tool is was designed as. If you can't say that the bearing will last for 3 hours, it shouldn't be flying.
HUMS didn't find the EC225 Epicyclic failure...
