## Discrepancy

DURING SCHEDULED MAINTENANCE A SMALL AREA OF SURFACE CORROSION WAS VISUALLY IDENTIFIED ON THE RIGHT WING UPPER AFT WING FITTING. (OEM PN: 0822550-46). THIS CORROSION MEASURES APPROX. 1.25" LONG WITH A MAX DEPTH OF APPROX. .009" AND IS CONSISTENT WITH OTHER CORROSION FOUND ON THESE FITTINGS IN THE PAST. THIS FITTING WILL BE CHANGED USING NEW PARTS.
