Abstract : The failure history of the FFE mode of the XM509/M577 system is reviewed together with the results of the investigations which lead to a workable solution to the problem. Since there is some evidence that structural vibrations are causing the malfunctions, an in-depth study of the structural responses of the XM509/M577, M483/M577 and M106/M577 system, together with an associated test program, is recommended in order to provide a more complete understanding of the phenomona.
