## Discrepancy

THE ENGINE SHUT DOWN ON FINAL APPROACH.  IT WILL NOT BE KNOWN UNTIL THE ENGINE IS APART ON WHAT EXACTLY FAILED.  IT IS SUSPECTED THAT THE TORQUE SENSOR FAILED.  THE FAILURE OF THIS UNIT CAUSED THE ACCESSORY DRIVE FOR THE ENGINE DRIVEN FUEL PUMP TO STOP ROTATION,  LOOSING FUEL TO THE ENGINE.  THE OCCURANCE WAS ON SEPT 16, 2003.
