## Discrepancy

PILOT REPORTED AN EXCESSIVE MAGNETO DROP ON LT AND RT MAGNETOS.  UPON FURTHER INSPECTION FOUND THE MAGNETOS FULL OF CORROSION AT HARNESS CONNECTION AND IN THE AREA WHERE POINTS ARE LOCATED.  THIS AIRCRAFT HAD NOT BEEN FLOWN IN A WHILE AND HANGARED FOR MOST OF THAT TIME.  THIS AIRCRAFT HAS PRESSURIZED MAGNETOS AND BELIEVE THIS COULD BE THE SOURCE OF THE MOISTURE.
