## Discrepancy

(CAN) DURING INSPECTION NOTICED SMOKING & LOOSE RIVETS AROUND INBOARD SIDE OF LT AND RT ENGINE NACELLE JUST AFT OF FIREWALL. REMOVED LOWER ACCESS PANEL AND FOUND THAT BOTH LT & RT INBOARD NACELLE PLATES P/N 41663-00 (LT) AND 41663-01 (RT) WERE CRACKED FROM L/E OF PLATE TO AFT END. THIS PLATE CREATE A WRAP AROUND L/E SKIN AND ATTACHES NACELLE STRUCTURE TO SKIN. PART REQUIRED TO BE REPLACED SINCE THERE IS NOT MUCH ROOM TO BE REPAIRED.
