What was found
THE LEFT NOSE TRUNNION SUPPORT BRACE HAD A STRESS CRACK AT THE TRUNNION MOUNT EAR. THE CRACK FINALLY CAUSED A FAILURE ON TAKEOFF AT KACT ON 10/25/2017. THIS FAILURE IN TURN CAUSED THE RIGHT TRUNNION SUPPORT TO FAIL AND ULTIMATELY COMPLETE NOSE GEAR COLLAPSE. DUE TO THE FRACTURE BEING 90% OLD AND THE LAST 10% CAUSING THE ULTIMATE FAILURE. IT IS RECOMMENDED THAT THE LEFT AND RIGHT NOSE TRUNNION SUPPORTS RECEIVE ADDITIONAL INSPECTIONS REQUIRING REMOVAL AT ANNUAL INSPECTIONS.
