Sikorsky have found issues using HUMS with other operators as well. From what I understand, not all these bearings are being removed for over limit exceedances either. Some have been removed for unexplained trends/spikes/rates that they would like to study and learn from..

With the expense to do the inspection and the $4M+ per seat liability, if a reinstalled bearing fails, no rationale person would ever reuse even a slightly degraded bearing or one that is spitting out "false" fault indications. Replacement bearings are relatively dirt cheap.
Again if you have to dig to see an issue or rely on someone in the ether to make a maintenance call it is not the operator/maintainer at fault. It is a half-ass HUMS which does not meet OGP expectations.
