    THE INSTRUMENT WAS RETURNED AND EVALUATED. FAILURE ANALYSIS FOUND THE INSTRUMENT'S PITCH CABLE TO BE BROKEN AT THE PROXIMAL CLEVIS HUB. THE CLEVIS DID NOT EXHIBIT ANY WEAR. BROKEN STRANDS WERE OBSERVED TO BE STICKING OUT AT THE WRIST OF THE INSTRUMENT. THE OTHER CABLES AT THE WRIST OF THE INSTRUMENT WERE UNDAMAGED. FAILURE ANALYSIS INVESTIGATION ALSO FOUND THE FOLLOWING DAMAGES: THE INSTRUMENT'S GRIP TIPS WERE BENT. ONE GRIP WAS BENT WHICH CAUSED SIDE TO SIDE MISALIGNMENT OF THE GRIP. THERE WAS A 0.011 OFFSET AT THE TIPS. THE BENT GRIP EXHIBITED SEPARATION OF THE YAW PULLEY AND PULLEY COVER AT THE GLUE JOINT, INDICATING LIKELY CAUSE OF BENDING REMAINS OVERLOADING AT THE TIP. FAILURE ANALYSIS CONCLUDED THAT THE BENT DAMAGE MAY BE DUE TO MISHANDLING/MISUSE. IN ADDITION, THE INSTRUMENT'S MAIN TUBE HAD SCRATCH MARKS/ABRASIONS. THE DISTAL END OF THE MAIN TUBE HAD VARIOUS SCRATCH MARKS WITH LIGHT MATERIAL REMOVAL. THE SCRATCHES WERE NOT ALIGNED WITH THE TUBE AXIS. NO OTHER DAMAGE WAS FOUND.
