curious to as if anyone has found their hinge bearings move in their housing as is the subject of a service bulletin of 8/2016 or 2017. mine both have moved apparently from taxiing? there has never been any trauma to my stab in the build or in my hangar. plane is waiting for this to be resolved for its first flight. tomorrow i will follow 5-20 in the maintenance manual to fix this. having a little trouble accepting the fact these bearings moved. it was noticed when the skin on the stab became tight against the fuselege.
