Jim, maybe the questions SAS is posing is valid for all those failures too. If we just sit back and accept it as part of the wallpaper of life then where, when and how do we progress.
There are stories about things going wrong at the factory that only come out years later. The saga of how the S76 tail rotor problems were suddenly solved overnight with a piece of kit that must have taken months to develop, the spindle saga, Bells combining gearboxes. Are they being straight with us or what?
When the Bell 412 gearbox (epicyclics) seized a couple of years back they managed an autorotation - why not the S92 and the 332L2?
