AFTER CORROSION REMOVAL, THE MATERIAL REDUCTION MEASURED APPROXIMATELY 2.265 INCHES LONG BY 1.165 INCHES WIDE TO A MAXIMUM DEPTH OF 0.014 INCHES DEEP, WHICH IS DEEP AND EXTENSIVE ENOUGH TO NECESSITATE THE REPLACEMENT OF THE PART. THE PART WILL BE REPLACED PER EMBRAER PRODUCTION DRAWINGS AND SRM CHAPTER 51 PRINCIPLES. NO FOLLOW UP INSPECTIONS ARE REQUIRED DUE TO DIRECT REPLACEMENT OF THE PART. COMPASS HAS CLASSIFIED THIS AS A MINOR REPAIR. WORK ORDER 2456860222
