## Discrepancy

DURING AIRCRAFT C5 CHECK,   MAINTENANCE DISCOVERED CRACK INDICATIONS ON THE RT INNER FRAME AT STA 903.5 WHILE ACCOMPLISHING AN HFEC SURFACE SCAN IAW REF D.  AN OPEN HOLE HFEC WAS COMPLETED IAW REF D WHERE IT WAS DISCOVERED THAT THE UPPER MOST FASTENER HOLE HAD BEEN OVERSIZED BY 1/32¿ (DIA 0.2728¿). REF /E/ WAS ISSUED TO PERFORM THE REPAIR ANGLE INSTALLATION IAW REF /C/. DURING ACCOMPLISHMENT, IT WAS DISCOVERED THAT THE REPAIR ANGLE INSTALLATION DID NOT PROVIDE ALLOWANCE FOR A FASTENER HOLE DIAMETER OF 1/32¿ GREATER THAN NOMINAL. BOEING WAS CONTACTED TO PROVIDE A PROPOSED REPAIR WHICH WAS THEN SENT TO IAI FOR FINAL APPROVAL AND TO PROVIDE THE FAA FORM 8110-3 AND AMOC FOR COMPLIANCE OF REF /B/. REPAIRED IAW ABX-REA-5350-66228-00/ ABX-EA-5300-0052-101.
