## Discrepancy

DURING INSPECTION, IT WAS NOTED THAT ENGINE NR 1 PYLON AFT FAIRING HEAT SHIELD SKIN NR 8 HAD AN EXISTING REPAIR AT THE AFT LOWER CORNER OF THE EXHAUST GRILL CUTOUT. ACCORDING TO PREVIOUS OPERATOR RECORDS, THIS REPAIR LACKS MATERIAL TRACEABILITY. CONSEQUENTLY, IT WAS REMOVED TO ALLOW A NEW REPAIR IAW SRM REQUIREMENTS. FOLLOWING REMOVAL, A CRACK WAS DETECTED AT THE UPPER CORNER OF THE EXHAUST GRILL CUTOUT. IN LIGHT OF THIS FINDING. DUE TO IT, DETAILS WERE SENT TO EMB AND WAS REPAIRED IAW ETD2026-190-013916 DTD,  AND DOCUMENTED PER COOPESA EO COO-EO-2026-24868-R00.
