At this year's annual inspection, we indicated to Chris Jacobs that we had the occasional shimmy issue. Chris elected to take off and stripped the nose wheel strut, rebuilt and re-shimmed it. This service would fix the issue for a short time unforetunately the shimmy returned.
The group chose to equip GGNQ with a more rugged shimmy damper. Click on the link to review a write up by Dave McFarlane regarding nose wheel shimmy.
