## Discrepancy

DURING PSV,  NDT INSPECTIONS DETECTED CRACK INDICATIONS IN A TOTAL OF 10 FASTERNER HOLE LOCATIONS ARE DETAILED IN FIG 4 OF ERA 508354-14.  SPLICE PLATES ARE TO BE REPLACED WITH THE 46A5342-26 SPLICE PLATES.  THE SB 737-53-1296 DOES NOT ADDRESS THE CRACKING IN THE LONGITUDAL FLOOR SUPPORT UPPER FLANGES.
