## Discrepancy

EMERGENCY RETURN TO FIELD:  INSPECTION REQUIREMENTS FOR MAGNETO (PN 6320) ARC NOT ADEQUATE TO INSURE PROPER VENTING (PRESSURIZED MAG).  SB2-80C SPECIFIES ONLY EXTERNAL INSPECTION IS REQUIRED EVERY 100 HOURS AND AN INTERNAL INSPECTION AFTER 500 HOURS.  THE SUBECT MAGNETOS WITH 525 AND 438 CONTAINED MOISTURE AND EXCESSIVE CORROSION INTERNALLY BECAUSE THE PREVIOUS REQUIREMENTS TO TEST PRESSURIZED MAGNETOS CONTAINED IN SB 1-88A DO NOT APPLY TO THE 6300 SERIES MAGNETOS.
