## Discrepancy

(CAN) DURING A SPECIAL INSPECTION AFTER FINDING DAMAGE ON ANOTHER AIRCRAFT, (SDR 20050829003) THE SAME TWO AREAS OF THE AFT PRESSURE BULKHEAD WERE FOUND CHAFED BY THE TWO INTERCOSTALS ADJACENT TO THE TAIL ACCESS DOOR. NDT WAS COMPLETED AND THERE WERE NO CRACKS FOUND. THE INTERCOSTALS WERE TRIMMED BACK TO MAINTAIN A CLEARANCE WHEN THE AIRCRAFT IS PRESSURIZED AND PREVENT FURTHER CHAFING AND POSSIBLE CRACKING. WE HAVE SET UP A FLEET CAMPAIGN TO INSPECT ALL OF OUR AIRCRAFT AS THEY COME DUE FOR THEIR NEXT PHASE INSPECTION.
