## Discrepancy

DURING THE REPEAT DETAILED VISUAL INSPECTION OF PART 2 OF EO4471A069 IT WAS FOUND THAT THERE WAS ADDITIONAL DAMAGE FOUND TO THE RIGHT CORE COWL.  A TIME LIMITED REPAIR WAS ACCOMPLISHED ACCORDING TO REVISION A OF THIS SAME EO & FAA 8110-3 DATED 28FEB11.  REPEAT INSPECTIONS WERE REDUCED FROM 15 FLIGHT CYCLES TO 5 FLIGHT CYCLES.  AN INTERIM REPAIR IS REQUIRED AT THE NEXT A CHECK AND A PERMANENT REPAIR IS REQUIRED AT THE NEXT D CHECK.
