Narrative:

Engine #4 flamed out at idle thrust during approach to hkg at 4500 ft MSL at 180 KTS. Light rain no turbulence. Restarted ok. Callback conversation with reporter revealed the following information: reporter indicated in the callback the maintenance department found that within the fuel control the hydraulically operated valve that allows or sends a signal to the stator vanes to modulate had failed. The application of power at the time of the flameout was following an extended idle descent. Restart was accomplished and engine operated normally throughout the rest of the approach and landing, including reversing and taxi.

Title: ACR HAS FLAMEOUT AT INITIAL APCH FIX. ENG RESTARTS.

Narrative: ENG #4 FLAMED OUT AT IDLE THRUST DURING APCH TO HKG AT 4500 FT MSL AT 180 KTS. LIGHT RAIN NO TURB. RESTARTED OK. CALLBACK CONVERSATION WITH RPTR REVEALED THE FOLLOWING INFO: RPTR INDICATED IN THE CALLBACK THE MAINT DEPT FOUND THAT WITHIN THE FUEL CTL THE HYDRAULICALLY OPERATED VALVE THAT ALLOWS OR SENDS A SIGNAL TO THE STATOR VANES TO MODULATE HAD FAILED. THE APPLICATION OF PWR AT THE TIME OF THE FLAMEOUT WAS FOLLOWING AN EXTENDED IDLE DSCNT. RESTART WAS ACCOMPLISHED AND ENG OPERATED NORMALLY THROUGHOUT THE REST OF THE APCH AND LNDG, INCLUDING REVERSING AND TAXI.
