## Discrepancy

DURING INSPECTION, A CRACK WAS FOUND AT THE LEFT LOWER FUSELAGE SKIN AT BS -5.375 WHERE THE FUSELAGE SKIN ENDS AT THE FIREWALL AREA.  THE CRACK EMANATED FROM THE EDGE OF THE SKIN, EXTENDED THROUGH A RIVET HOLE AND BACK OUT, ANGLING BACK TOWARDS THE SKIN EDGE AGAIN.  THE CRACK WAS APPROXIMATELY 1.5 INCHES LONG WHEN DISCOVERED.  A PROPER SKIN REPAIR WAS ACCOMPLISHED.  RECOMMEND A CLOSE LOOK IN THIS AREA DURING SCHEDULED INSPECTIONS.   NO DEFINITE CAUSE WAS FOUND TO HAVE CAUSED THIS PARTICULAR DEFECT.  (X)
