## Discrepancy

UPON INSPECTION OF THE L/H SPONSON UPPER CENTRAL ATTACHMENT POINT (FS 361) WE HAD EVIDENCE OF LOOSE HARDWARE. UPON REMOVAL OF HARDWARE, WE FOUND THE BOLTS CORRODED AND CORROSION WITHIN THE BUSHING OF THE HOLE. THERE IS NO EVIDENCE OF FRETTING OR MUD WHERE THE SPONSON ATTACHES TO THE AIRFRAME WITH THE SPONSON INSTALLED.  UPON REMOVAL OF SPONSON CORROSION WAS FOUND ON THE MOUNTING PAD REQUIRING REPAIR BEYOND SRM LIMITATIONS.
