DESCRIPTION: ON 06-MAY-2025 PRIOR TO FLIGHT UTILIZING AIRCRAFT (A/C) N633JB (MSN: 02671) @ SJU, AN UNKNOWN IMPACT DAMAGE WAS FOUND ON THE REAR FUSELAGE EXTERNAL SKIN (PN: D5348001620000) NEAR THE LAP JOINT @ FR 64-65 & STGR 32L-33L, CAUSING A DENT WITH A GOUGE.  THE DAMAGE WAS LEFT AS IS AND THE DIMENSIONS ARE REPORTED AS 2.65 L X 1.70” W X 0.142” D, THE DEEPEST POINT OF THE DENT LOCATED ~ 1” FROM STGR 32L IN THE DIRECTION TOWARDS STGR 33L, AND 6” FWD OF FR 65.  PER THE REPORT, ALL DAMAGES ARE LOCATED IN THE UNRIVETED AREA.  A 10X MAGNIFIED EXTERNAL DVI WAS ACCOMPLISHED WITH NO FINDINGS.  SEE REF /1/ DAMAGE REPORT AND MAPPING FOR FULL DETAILS. THE SKIN WAS IDENTIFIED USING SRM IDENTIFICATION REF /5/ AND FOUND TO BE 1.6MM (0.063IN) THICK AND MADE OF 2024T3 AL IAW DAN20.  THE DEFECT WAS FOUND TO BE OUT OF LIMITS (OOL) IAW REF /6/ ADL (REFERENCE FIGURE 006 SHEET 3 OF 4) DUE TO BEING IN AN EXCLUDED ZONE LOCATED NEAR THE LAP JOINT.  THE A/C WAS FERRIED FROM SJU TO BHM VIA REF /2/, ECA. AIRBUS WAS CONTACTED FOR DISPOSITION VIA REF /3/ AND ON 5/10/2025 AIRBUS PROVIDED REF /8/ TD ISSUE A TO DO THE NDT INSPECTIONS AND PERFORM THE REPAIR AS PER REF /7/ SRM INCLUDING THE DEVIATION TO USE CCC IN LIEU OF CAA. AIRBUS PROVIDED REF /4/ RDAF ISSUE A TO COVER A DISCREPANCY ON REF /9/ SRI TASK TABLES 1 AND 2 THAT DO NOT LIST ANY INSPECTION REQUIREMENTS FOR WV 017 AND REPAIR INSTRUCTIONS PROVIDED REF /8/ TD. THE REF /4/ TEMPORARY RDAF APPROVAL ALLOWS FOR 200 FLIGHT CYCLES UNTIL THE DESIGN TEAM PROVIDES FATIGUE SUPPORT. EC A24-464-01 REV 02 HAS BEEN ISSUED TO ACCOMPLISH THE REPAIR PER REF /8/ TD WHICH IS APPROVED BY RDAF REF /4/. EC A24-464-02 IS BEING ISSUED TO TRACK THE COMPLETION OF FATIGUE ANALYSIS DUE IN 200 FC AS PER RDAF REF /4/. NOTE- AIRBUS HAVE REFERENCED THE INTERNAL TRM MESSAGE /036 IN THE RDAF REF /4/, TO WHICH WE DO NOT VISIBILITY. A REQUEST HAS BEEN SENT TO AIRBUS VIA TRM MESSAGE /066 TO UPDATE THE RDAF. THIS EC WILL NEED TO BE REVISED ONCE THE UPDATED RDAF RECEIVED. SUBSTANTIATION: THE PERMANENT REPAIR IS PENDING DTA DUE WITHIN 200 FC AND THIS EC IS CLASSIFIED AS OTHER.* REV 01* /10/ AIRBUS RDAF 81587668/002/2025 ISSUE B. ON MAY 10, 2025, AIRBUS PROVIDED REF /10/ RDAF ISSUE B, CORRECTING THE MESSAGE REFERENCE. REF /4/ RDAF ISSUE A HAD REFERENCED MESSAGE /036 OF THE DOSSIER, WHICH WAS AN INTERNAL AIRBUS MESSAGE NOT VISIBLE TO JBU. THE CURRENT RDAF ISSUE B CORRECTLY REFERENCES MESSAGE /042 FOR THE WV 17 APPROVAL FOR SRI TASK 53-41-11-205-103. THIS EC IS BEING REVISED TO ATTACH REF /10/ RDAF ISSUE B ONLY.
