    THE INSTRUMENT WAS RETURNED AND EVALUATED. PER THE CUSTOMER REPORTED COMPLAINT, FAILURE ANALYSIS FOUND THE INSTRUMENT'S GRIP TIPS TO BE BENT. ONE GRIP WAS BENT WHICH CAUSED SIDE TO SIDE MISALIGNMENT OF THE GRIP. THERE WAS A 0.150 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. FAILURE ANALYSIS WAS UNABLE TO CONFIRM THE CUSTOMER REPORTED COMPLAINT OF WIRE BROKE. THE INSTRUMENT WAS INSPECTED UNDER A DIGITAL MICROSCOPE AND NO BROKEN WIRES WERE NOTICED. FAILURE ANALYSIS INVESTIGATION ALSO FOUND THE INSTRUMENT'S MAIN TUBE HAD SCRATCH MARKS/ABRASIONS. IN ADDITION, 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. THE INSTRUMENTS AND ACCESSORIES USER MANUAL SPECIFICALLY STATES: GENERAL PRECAUTIONS AND WARNINGS HANDLE INSTRUMENTS WITH CARE. AVOID MECHANICAL SHOCK OR STRESS THAT CAN CAUSE DAMAGE TO THE INSTRUMENTS. THE CUSTOMER REPORTED COMPLAINT DOES NOT IN ITSELF CONSTITUTE A MDR REPORTABLE EVENT; HOWEVER; THE VARIOUS SCRATCH MARKS ON THE MAIN TUBE WITH LIGHT MATERIAL REMOVAL FOUND DURING FAILURE ANALYSIS IF TO RECUR COULD CAUSE OR CONTRIBUTE TO AN ADVERSE EVENT.
