Hi list.

I had flutter all last flying season. It started occasionally and got
worse over time.
It's like Ed describes it. The immediate remedy is intuitive. You start
steering and the flutter disappears.
My flutter started at speeds above 110 MPH.
I knew it's the play in the controls. I just did not know where exactly.

Now, after pulling the wings for the Center section inspection (yes, we
found corrosion), I found ALL!!!! elements of the right aileron control
worn.
I replaced all rod ends and also the expensive bearings in the outer
aileron bellcrank.
In case I ever get the plane back into flying condition I will see if
the flutter is gone.
But I am pretty sure of it. By the way. I had the flutter at almost all
of my last flights and got pretty much used to the annoying washboard
feeling. I had time to experiment a bit and can assure that the wing
does not fall off the moment you're experiencing it , nor does the
aileron. So no panic, do some gentle turns and slow down. That's all to
be out of it.
