FAA 2023-25-02

Requires inspecting the left and right control column mounts to determine if a retaining ring is installed. If a retaining ring is not installed, this AD requires inspecting the bearing in the mount block for the presence of retaining compound, and, depending on the inspection results, installing a retaining ring and applying retaining compound to the bearing, as applicable. Prompted by a report that a bearing fell out of a control column mount during routine handling before installation in an affected airplane and the discovery that a quality escape condition could exist on other airplanes.
