## Discrepancy

UPON REMOVAL OF RUDDER, THE UPPER ATTACH BOLT WAS FOUND SEVERELY WORN TO THE POINT FAILURE WAS INEVITABLE.  THIS PROBLEM HAS BEEN NOTED BEFORE ON A R-985 B-MODEL.  THE SUSPECT CAUSE FOR THIS DEFECT WAS LACK OF PROPER INSPECTION.  WITH PROPER INSPECTION AND PREVENTIVE MAINTENANCE, THIS DEFECT WOULD NOT BE A PROBLEM.  SUBMITTER RECOMMENDS THAT EVERY 2,000 HOURS THE RUDDER ATTACH BOLTS BE REMOVED AND VISUALLY INSPECTED.
