## Discrepancy

A SMALL 3 BY 5 INCH BULGING SECTION OF THE BELLY SKIN WAS NOTED DURING INSPECTION. SKIN BULGE WAS LOCATED IN THE CENTER WING SECTION ON THE BELLY OF THE ACFT. TWO RIVETS HAD PULLED THROUGH AND THREE ARE PRESENTLY STRESSED. REMOVED ADF ANTENNA AND A BORESCOPE INSPECTION DID NOT REVEAL ANY USEFUL INFORMATION.  AN EDDY CURRENT INSPECTION REVEALED NO CRACKS IN THE SKIN PANEL.  AN ULTRASONIC THICKNESS INSPECTION WAS PERFORMED, ALSO WITH NO USEFUL FINDINGS. THE SKIN PANEL WILL BE REMOVED FOR FURTHER INSPECTION AND REPAIR OF THE UNDER LYING STRUCTURE. OPEN
