## Discrepancy

PRESSURIZED SLICK MAGNETOS ON CESSNA T210L.  DURING ANNUAL, INSPECTED MAGS INTERNALLY FOR CONDITION.  FOUND SEVERE MOISTURE-CASED CORROSION ALL AROUND INSIDE.  MAGNETO MANUAL CALLS FOR INSPECTION OF 6200 SERIES EACH 100 HOURS, NOTHING FOUND FOR INSPECTION OF 6300 SERIES.  MANUAL SAYS TO CLEAN CORROSION AND RE-INSTALL.  CORROSION SO EXTENSIVE, MAGS REPLACED.  SLICK AD 88-25-04 ADDRESSES THIS PROBLEM, BUT THESE MAGS, 6320 SERIES, ARE NOT IN THE APPLICABILITY SECTION.  SUBMITTER STATED AD SHOULD BE REVISED TO INCLUDE 6300 SERIES PRESSURIZED MAGNETOS.  (X)
