Probable cause
A worn component within each engine integrated drive generator (IDG) resulted in the loss of electrical power supplied to several flight deck displays and systems while on approach to landing. The component, a fixed cylinder block, had significant wearing of its reworked brass liners resulting in the IDGs producing a frequency output outside of their specified design limit.
