## Discrepancy

T/R TURNNION P/N 109-0131-05-111 TT: 2360.8. THE TRUNNION SHOWED SIGNIFIGANT WEAR AT DISSASSEMBLY AFTER THE PILOT NOTED A HIGH FREQUENCY VIBRATION. THE AGUSTA T/R ASSY IS SUBJECT TO BECOMING STIFF, WHEN THIS OCCURS THE T/R HUB SHOULD BE COMPLETELY DISSASSEMBLED AND INSPECTED FOR WEAR. I WOULD SUGGEST AGUSTA INSTITUTE A SCHEDULED INSPECTION PRIOR TO THE 2400 HR. INSPECTION THAT IS NOW IN PLACE.
