## Discrepancy

DURING RUN-UP BEFORE TAKEOFF, THERE WAS EXCESSIVE RPM DROP ON RT ENGINE, RT MAGNETO.  REMOVED RT MAGNETO.  REMOVED BACK COVER AND MAG HAD A BURNED ELECTRICAL ODOR.  REMOVED COIL AND FOUND TO BE ARCING TO CASE.  LOOKS LIKE THERE WAS A SMALL CRACK IN COIL HOUSING.  INSTALLED NEW MAGNETO AND RETURNED ACFT TO SERVICE.
