## Discrepancy

THE FUSELAGE HORIZTONAL PRESSURE DECK PANEL WAS FOUND WITH TWO CRACKS APPROX .75 INCH LONG EACH.  THE CRACKS ARE LOCATED AT RBL 102, JUST AFT OF STA 378, AND EXTEND DIAGONALLY INBOARD/ AFT AND OUTBOARD/ AFT FROM THE FORWARD EDGE OF THE PANEL AT THE EXISTING FRAME CUTOUT.  ONE OF THE CRACKS EXTENDS TO THE LOWER INTEGRAL PANEL STIFFENER AT APPROX RBL 102.  THESE CRACKS WILL BE REPAIRED WITH A DOUBLER.
