## Discrepancy

(CAN) THE ENG HAD AN UN-COMMANDED AUTO FEATHER EARLIER TODAY ON THE NR 1 ENG.  TROUBLESHOOTING HAS DETERMINED THE CAUSE TO BE A LOSS OF TORQUE SIGNAL ON THE NR 1 ENG.  THE FDR DATA ANALYSIS REVEALED AN OVER TORQUE.  THE ENG WAS REMOVED & WILL BE SENT FOR REPAIR.  MFG WILL INVESTIGATE TO ESTABLISH ROOT CAUSE & PROVIDE INFORMATION THROUGH SUBSEQUENT SERVICE DIFFICULTY REVIEW MEETING & SUPPORTING DOCUMENTS OR OTHER AGREED UPON COMMUNICATIONS.
