"ACTV ADAHRS VIBRATION" message

[Dragnet12]

On a Zenith Cruzer the ADAHRS is mounted on the floor of the cabin just aft of the baggage compartment and the belly access panel. Has been working well, but recently started getting message saying "ACTV ADAHRS VIBRATION". Nothing loose, nothing different as far as I can tell. Dynon user guide just says to "troubleshoot" and "fix" the problem.

Does anyone have any ideas on just how to do that? Should I use a dampener of some type? Thanks.

Well, here's one way *not* to do it. Yes, this was actually someone's installation, found by someone over at VAF during an inspection...

I had an issue with vibration when I first bought my aircraft that had 300 hours on it so don’t know why it had not been fixed. My fix was to strengthen and stiffen the mount the adahrs was on. I was tempted to use rubber mounts but it was not necessary and probably not advisable either.

Thanks. This seems to be the consensus.

Well, it would have done *something* . I guess it depends on what your definition of "work" is LOL!
