REFLECTOR: Front Vibration

[Jack Sheehan]

I have had a similar problem but only at high speed over 190kts 
indicated. I know you checked the main gear doors. In my case 
although the gear doors looked to be tight on the ground after a 
little time the system would allow them to sag ever so slight and a 
noise and vibration would appear. I was able to make the noise go 
away by just tapping the gear reset button for an instant ( I know 
the warning says do not push reset in the gear up position) After 
that discovery I checked the main gear cable tension and on the 
ground in the gear down position the cables were just a little loose 
so an adjustment to tighten the cables fixed the problem. On a recent 
flight after about three hours and in decent it did it again so the 
cables seem to stretch or other things loosen up a little( pulleys 
etc). My noise and vibration did seem to be more from the engine area 
not the canard but did not seem to be from the gear doors and I was 
surprised at the very little adjustment that fixed it.
Good luck
