## Discrepancy

NR 2 MAIN JOURNAL THROUGH-BOLT WAS BROKEN AT TOP OF NR 2 CYLINDER.  NO OTHER DEFECT NOTED.  PILOT DID NOT STATE ABOUT ANYTHING TO CAUSE THIS, ALL OTHER ASSOCIATED ATTACH POINTS INSPECTED OK.  ENGINE ONLY HAS 146.6 TSMOH AT FACTORY.  PER SB 97-6, THROUGH-BOLTS ARE NOW REPLACED WITH NEW.
