## Discrepancy

WOODWARD RB211-535 CONTROL SN WYG 2328482  RETURNED DUE TO IN-FLIGHT SHUT DOWN (IFSD).  INVEST CONFIRMED AN FFG MALFUNCTION WAS THE CAUSE OF THE IFSD AND MALFUNCTION CAUSED BY DISBONDMENT OF A REPAIR BUSHING WHICH HAD BEEN PERFORMED ON THE FUEL VALVE HOUSING WHEN NEW IN 1991.  THIS EPOXY REPAIR WAS CONSIDERED PERMANENT.  THE CAUSE OF DISBONDMENT IS UNDER INVEST.  TO DATE, A SEARCH OF WOODWARD RECORDS INDICATES ONE OTHER FUEL VALVE HOUSING CONTAINS THIS IDENTICAL REPAIR.  IMMEDIATE CORRECTIVE ACTION WILL BE FOR WOODWARD TO REQUEST 'RETURN FOR INSPECTION' OF OTHER S/N IN ORDER TO FURTHER ASSESS REPAIR.  DETAILS REGARDING INCORPORATION OF A LONG TERM CORRECTIVE ACTION FOR THIS ISSUE WILL BE COORDINATED WITH RR.
