## Discrepancy

DURING AIRCRAFT DESCENT AT 30000 FT, ENGINE NR 3, NR 4 FLAMED OUT WHILE ENCOUNTERING HEAVY RAIN AND MODERATE TURBULENCE.  BOTH ENGINES WERE BACK TO NORMAL AFTER RESTART.  THIS CASE IS BEEN DETERMINED AS WEATHER CAUSED IFSD (IN-FLIGHT SHUT DONE) AT OCT/2004.   MFG IS GOING TO REVISE THE FADEC VBV SCHEDULE TO OPEN VBV TO PREVENT SEPARATED ICE FROM GETTING INTO HPC/COMBUSTOR AT 1Q/2005.
