NOSE GEAR. Rubber Bumper Modification. Original Part

After several landings, the steel face in contact with the nose gear strut on the original rubber shock bends inward compressing the rubber and diminishing its shock absorbing properties. This creates a gap between the rubber shock and the strut, while on the air (unloaded). Upon lowering the nose on landing, this gap closes and the strut hits hard against the deformed metal face of the bumper with very little, if any, shock absorbing action. This results in a somewhat rough nose gear drop and taxiing. In addition, some pilots have experienced significant shimmy a few times with properly-torqued nose gear washers that they have attributed, at least in part, to this condition. The fix from the factory was to add an aluminum plate between the rubber shock and the strut to eliminate the gap.
