Years ago, flying Lynx, I encontered unusual vibrations in flight while collective down only. It turns out to be a missing part in the collective control chain, but under lift, there was no vibs.
HUMS picks up vibrations and frequencies that could NEVER be felt or heard by humans- that's the beauty of it. The problem is interrogating and deciphering all the data into something meaningful. Cue the authority to take a proactive role for a change.
