## Discrepancy

DURING STRUCTURAL INSPECTION, THE CUSTOMER FOUND AN EXTERNAL REPAIR DOUBLER AT FR74 + 105 MM AND STR 24L + 85 MM, REPORTEDLY INSTALLED IN ACCORDANCE WITH EMB IC2009-190/05358C DATED 09-JUL-2009. ONCE THE AVAILABLE DOCUMENTATION LACKED ESSENTIAL INFORMATION, THE REPAIR WAS REMOVED, EXPOSING AN EXISTING SKIN CUTOUT BENEATH THE DOUBLER. A NEW REPAIR WAS ATTEMPTED FOLLOWING SRM 53-23-01, REPAIR 62, BUT THE REQUIRED DOUBLER FOOTPRINT EXTENDED INTO THE NONREPAIRABLE “GREY ZONE” IDENTIFIED IN FIGURE 205 OF SRM 53-23-01. TO RESOLVE THIS, A NEW REPAIR SKETCH WAS DEVELOPED USING THE CRITERIA OF SRM 53-23-01 AND SRM II 51-75-00, APPLYING THE “NO-FINGER” METHOD DEFINED IN SRM 51-75-17. THIS CONDITION REPORTED WAS REPAIRED IAW ETD2026-190-001344 DTD JAN 27 2026 AND DOCUMENTED UNDER COOPESA EO COO-EO-2026-23824-R00. JOB A1Q328 ITEM 21-30
