## Discrepancy

LEFT ENGINE IDG (INTEGRATED DRIVE GENERATOR)  LIGHT STARTED FLICKERING AND THEN CAME ON STEADY ABOUT 20 MINS LATER.  IDG WAS DISCONNECTED.  SUPPLEMENTAL DATA UPDATE FOUND INTEGRATED DRIVE GENERATOR (IDG) FAILED.  INTERNAL LEAK WAS DUE TO WARN BLOCK FACES OF IDG, RESULTING IN LOW IDG PRESSURE.  REPLACED LEFT INTEGRATED DRIVE GENERATOR (IDG).
