## Discrepancy

(CAN) DURING THE CONTINUING AIRWORTHINESS STRUCTURAL INSPECTION CHAFFING DAMAGE WAS FOUND ON THE AFT SIDE OF THE AFT PRESSURE BULKHEAD. THE LOWER CENTER AND THE LOWER RT INTERCOSTALS RUBBING ON THE BULKHEAD DURING PRESSURIZATION CAUSED THE DAMAGE. FURTHER INVESTIGATION (EDDY CURRENT) FOUND THAT THE BULKHEAD WAS CRACKED AT THE CENTER INTERCOSTAL LOCATION.
