## Discrepancy

DURING ACCOMPLISHMENT OF EO E17X-57AD-001.1, A BUSHING FROM PRODUCTION WAS DISCOVERED IN A SB 170-57-0053, REWORKED FASTENER HOLE.  SINCE THE DAMAGE IS NOT COVERED IN THE SB, A REPAIR WAS REQUESTED FROM MFG AND PROVIDED BY ETD2013-170-037735A AND APPROVED BY FORM 8110-3.  BECAUSE THIS STRUCTURE IS PSE, ACCOMPLISHMENT OF THIS EO HAS BEEN CLASSIFIED AS A MAJOR ALTERATION FOR THE ACCOMPLISHMENT OF SB 170-57-0053 AND A MAJOR REPAIR FOR THE ELIMINATION OF THE COLD WORKING PROCESS ON 1EA SUBJECT FASTENER HOLE THAT HAD A BUSHING INSTALLED AT PRODUCTION.  THE ACCOMPLISHEMENT OF THIS REPAIR WAS ON EO E17X-57AD-001.6.
