What was found
DURING ANNUAL INSPECTION, FOUND RUDDER SPAR CRACKED ON EDGE OF ALUMINUM SPACERS MOUNTED UNDER TOP RUDDER HINGE. CRACK SEEMS TO ORIGINATE FROM EDGE OF ALUMINUM SPACERS POSSIBLY FROM FLEXING IN THIS AREA. THIS IS A VERY HARD AREA TO SEE WELL DURING NORMAL INSPECTION AND MAJORITY OF THE CRACK WAS HIDDEN BY THE EDGE OF THE SPACER. CRACK WAS DISCOVERED WHEN RUDDER WAS REMOVED FOR UNRELATED MAINTENANCE.
