I’ve noticed a few posts talking about nosewheel shimmy and thought I’d give you some background info on the issue. I don’t ever remember seeing it on the 20 but on one early 22 high speed taxi test I thought the nose gear was going to break off because it shook so badly. We worked diligently to get the shimmy out but I left before the 22 was certified so I don’t know what the final configuration consisted of. The good news was that after that particular test the nose gear and associated hardware were no worse for the wear. No one likes to have any shimmy (and I’m not trying to dismiss it) but I would say IMHO that I don’t think there should be any immediate concern on hurting you or the airplane if experiencing a small amount of shimmy on occasion.
