What was found
THE RIGHT MAIN GEAR IDLER BELL CRANK ASSY BROKE IN HALF. THE BREAK CAUSED THE INNER GEAR DOOR TO HANG FREE. THE POINT OF FAILURE HAD RUST IN THE CRACK. THE GEAR DOOR APPEARS TO HAVE CAUGHT ON THE FAIRING WHILE OPENING AND THAT IS WHAT ADDED THE STRESS TO THE BELL CRANK AND LEAD TO ITS FAILURE. THE GEAR/GEAR DOOR TENSIONS/ RIGGING HAD BEEN VERIFIED AT LAST ANNUAL INSPECTION 34 OPERATION HOURS PRIOR AND WAS WITHIN LIMITS.
