## Discrepancy

DURING ROUTINE INSPECTION, LT MAGNETO WOULD NOT TIME, REMOVED, OPENED TO CHECK POINTS, FOUND SEVERE ARCHING FROM BRUSH TO THE POINT OF BEARING BAR FAILURE. SN FROM BOTH MAGNETOS AFFECTED BY SB3-08A, BOTH MAGNETOS FAILED INSP AND REPLACED. DOWN SIDE, REPLACEMENT (NEW) MAGNETOS ARE STILL AFFECTED, REQUIRING INSPECTION WITHIN 25 HRS. (K)
