I started experiencing a strong tailwheel shimmy when I land my S1-T (When I initially got the plane, there was no shimmy)
The shimmy does not occur all the times. The typical situation when the shimming occurs is when I land a tad too fast, with the stick not all the way back. As I bring the stick back with the tailwheel already on the ground, I experience a strong shimmy for a second or two,then it goes away, sometime it comes back and then it goes away as the plane slow down. Recently, however, there is shimmy also at lower landing (ground) speeds, when there is a 20 knot wind blowing down the runway. And the shimmy is even stronger.
The geometry of the leaf spring is unchanged and I have already replaced the two lateral springs on the tailwheel, which is the one that Aviat installs on all the Pitts. Everything appears to be normal in the tailwheel. The only thing that has changed is the wear of the tire
Any idea about what could be causing the shimmy and any suggestion about how to eliminate it?
