## Discrepancy

DURING MX, THE LEFT OTBD FLAP, OTBD TRACK WAS BLEEDING RUST. UPON DISASSEMBLY, THE TRACK WAS FOUNDED CORRODED. THE CORROSION WENT BEYOND THE CMM LIMITS.  MFG ENGINEERING ISSUED AN REA TO FURTHER CLEAN THE CORROSION WITH ADDITIONAL LIMITS ESTABLISHED. THE CORROSION WAS REMOVED, PART WAS INITAL ETCHED, FMPI INSPECTED, SHOT PEENED AND CAD PLATED. THE TRACK WAS REINSTALLED AND THE FLAPS RIGGED. THE ITEM WAS RETURNED TO SERVICE.
