DURING AN INSTRUMENT DESCENT FROM CRUISE, THE ELEVATOR TRIM CABLE FAILED. THE CREW EXPERIENCED INCREASING NOSE DOWN PITCH REGARDLESS OF INPUT. A SAFE LANDING WAS ACCOMPLISHED BY BOTH PILOTS PULLING AFT ON THE YOKE TO OVERCOME PRESSURE, AND LOWERING FLAPS AND LANDING GEAR 50 AND 20 KNOTS ABOVE THEIR RESPECTIVE OPERATING SPEEDS TO REDUCE THE TRIM FORCES AND HELP SLOW THE AIRPLANE. INSPECTION REVEALED THAT THE TRIM CABLE HAD BEEN INCORRECTLY ROUTED AROUND A CABLE GUIDE DURING INITIAL PRODUCTION, AND HAD NOT REACHED THE FIRST REQUIRED INSPECTION WHICH WOULD HAVE ALLOWED THE DISCREPANCY TO BE DISCOVERED.
