Hear what you say TenTon, but surely it's just a matter of time, albeit a few years, before HUMS info is indeed analysed - at least in part - in real time and cockpit warnings are provided for the most serious anomalies. But maybe this already happens to an extent? Also be interesting if the CVR picked up any observations from the most basic HUMS device - the crew - of any increase in vibration levels before failure.
