## Discrepancy

DURING A ROUTINE 100 HOUR INSPECTION IT WAS NOTED THAT THE ELECTRODE WAS MISSING FROM THE IGNITER PLUG.  FURTHER INVESTIGATION REVEALED THAT IT HAD CAUSED DAMAGE TO THE NG NR 1 BLADE WHEN IT BROKE LOOSE AND SEPARATED FROM THE IGNITER.  FURTHER ANALYSIS IS REQUIRED TO DETERMINE ACTUAL CAUSE OF THE FAILURE.
