What was found
WHILE C/W UNDER PANEL ITEMS ON ANNUAL CHECKLIST, FOUND ARM ON THE ELEVATOR CONTROL TUBE VERY LOOSE. DISASSEMBLY SHOWED HOLE WHERE ARM MOUNTS TO TUBE VERY ELONGATED. PART REPLACED WITH NEW PART. SUGGEST PHYSICALLY CHECKING EACH ARM FOR UNWANTED MOVEMENT WHEN DOING INSPECTION, NOT JUST VISUAL INSPECTION.
