## Discrepancy

DURING A-CHECK INSPECTION, LEFT FUSELAGE SKIN WAS FOUND TO HAVE A FREE FLOATING HORIZONTAL CRACK MEASURING 9.07 MM, 0.35", WITH A 3.47 MM, 0.13", CRACK TRAVELING UP FROM IT AT FRAME 75 ABOVE STRINGER 2L.  MAINTENANCE REMOVED THE DAMAGED SECTION OF SKIN AND PERFORMED A TRIPLER REPAIR IAW EC5330-02353, AND THE ACFT WAS APPROVED FOR RETURN TO SERVICE.
