Satcomm - I think you're making quite a large jump there. I'd say the footnote on page 4 more or less clarifies the ananlyis tool was available to view, just missed by whoever was inspecting it.
"The IMD-HUMS includes the use of additional stand-alone mechanical diagnostic software tools for the HUMS
Ground Station (GS) that help assess the condition of a number of specific components, one of which is the Tail
Gearbox Bearing Energy Analysis software tool; however, these require the user to visually inspect the data and
search for exceedances. The helicopter manufacturer now offers an alternative GS analysis system which offers
a number of enhancements to IMD-HUMS, including more advanced algorithms and the automatic alerting of all exceedances on receipt of new HUMS data."
