## Discrepancy

OPENED PRESSURIZED MAGNETO TO INSPECT FOR CORROSION DURING ANNUAL INSPECTION.  DETECTED A LARGE AMOUNT OF OIL IN AFT CASE OF MAGNETO.  FURTHER INVESTIGATION REVEALED THAT IT IS DIELECTRIC FLUID FROM CAPACITOR.  TESTED CAPACITOR WITH A SIMPSON METER AND WAS FOUND TO HAVE FAILED.  SUBMITTER FEELS THAT MAGNETO FAILURE WAS EMINENT DUE TO OIL CONTAMINATION TO POINTS AND DISTRIBUTOR.  SUBMITTER SUGGESTS INSPECTION OF ALL MAGNETOS CONTAINING THS PN CONDENSOR BEFORE FURTHER FLIGHT.
