212man, I hear you and would like to be convinced that the way the S-92s have been operated over here has not contributed to the stud failures. Would a detailed examination of various sources of S-92 HUMS data not give us a feel for common/abnormal inherent vibration issues at the MGB? Just wondering when we're going to find out the root cause failure mode for the titanium studs so that we can move forward with confidence that the replacement steel studs cannot suffer from the same fate. I'm assuming that there is now increased maintenance/inspection frequency on these studs, perhaps even change out of the studs every time the filter housing is removed. Can Horror box or someone else in the maintenance crews confirm this?
