## Discrepancy

DELAMINATION OF LEFT WING INBOARD AFT FLAP TRAILING EDGE WAS ORIGINALLY FOUND TO BE WITHIN LIMITS SO SPEED TAPE WAS APPLIED AS A TEMPORARY REPAIR AND THEN PLACED ON CARRY OVER.  THE FLAP WAS MONITORED UNTIL THE CONDITION DETERIORATED BEYOND LIMITS SO IT WAS RECOMMENDED BY MAINTENANCE CONTROL TO REMOVED AND REPLACED IT.
