## Discrepancy

DURING MAINTENANCE AN AREA OF CORROSION WAS IDENTIFIED ON THE RIGHT HAND LOWER AFT OUTBOARD SPAR CAP P/N: 5122041-24. THIS CORROSION IS LOCATED BETWEEN RIGHT WING STATIONS 223.21 AND 228.71, AND MEASURES 5.5 INCHES LONG BY .75 INCHES WIDE, AND HAS A MAX DEPTH OF .025 INCHES DEEP. THESE MEASUREMENTS ARE BEYOND THE REPAIRABLE LIMITS ALLOWED FOUND IN MEB 95-11R1. THIS CAP WILL BE REMOVED AND REPLACED WITH A NEW PART.
