ICA INSTRUCTIONS CALL FOR REMOVING THE SADDLE AND REBONDING AND RECLAMPING THE SADDLE TO THE CROSSTUBE. THE SADDLE WAS REMOVED AND A CRACK WAS FOUND IN THE CROSSTUBE IN THE AREA OF THE OF THE INBD CLAMP. THE CRACK PROGRESSED FROM THE TOP OF THE CROSSTUBE DOWNWARD AND WAS NOT VISIBLE AS IT PROGRESSED UNDERNEATH THE ATTACHMENT CLAMP. THE 2 YEAR INSPECTION CALLS OUT REMOVING THE CLAMPS FOR INSPECTION OF THE CROSSTUBE AND REINSTALLATION OF THE CLAMPS. THE CRACK WOULD HAVE BEEN VISIBLE AT THIS TIME.
