## Discrepancy

IAH - FLT 3671 - DURING DESCENT FROM 12,000 FEET, A LOUD POP WAS HEARD FROM NR 1 ENGINE FOLLOWED BY A DECREASE IN TEMPERATURE, TORQUE, AND ENGINE SPEED.  IGNITION LIGHT CAME ON BUT ENGINE DID NOT RE-LIGHT.  THE CREW FOLLOWED THE ENGINE FAILURE CHECK LIST AND LANDED WITH NR 1 ENGINE SHUT DOWN WITHOUT ANY FURTHER INCIDENT.  EXTENSIVE TROUBLESHOOTING BY MAINTENANCE SHOWED FUEL MANAGEMENT PROBLEMS.  THE HMU WAS REPLACED AND A COMPLETE CONTROL RIGGING AND ADJUSTMENT WAS ACCOMPLISHED.  OPS CHECK AND LEAK CHECK WERE GOOD.  THE AIRCRAFT PERFORMED A FUNCTIONAL CHECK FLIGHT WITH SATISFACTORY RESULTS.  (X)
