## Discrepancy

JUST PRIOR TO AIRCRAFT BEING INDUCTED FOR 100-HOUR INSPECTION, PILOT INFORMED MAINTENANCE OF ROUGH RT MAG ON RT ENGINE.  INVESTIGATION SHOWED SEVERE CORROSION ON POINTS, GEARS, CAPACITOR, AND BEARINGS.  CHECK REMAINING 3 MAGNETOS AND FOUND IDENTICAL CONDITIONS OF SEVERE CORROSION.  ALL FOUR MAGNETOS WERE CLEANED AND AFFECTED PARTS WERE REPLACED.  PROBLEM BELIEVED TO BE CAUSED BY PRESSURIZED AIR FROM TURBOS.
