## Discrepancy

CORROSION OR DAMAGE HAS BEEN DISCOVERED ON THE FWD CARGO (FWD P/N 170-67115-001) AND/OR
(AFT P/N 170-67115-002) FINGER DOUBLERS ON SEVERAL COMPASS AIRCRAFT DURING BASIC CHECK. SINCE EMBRAER
CLASSIFIES THESE FITTINGS AS PSES, COMPASS HAS CLASSIFIED REPLACEMENT OF THESE FITTINGS AS A MAJOR REPAIR. IN LIEU OF
CONTINUING TO WRITE INDIVIDUAL EOS FOR EACH AIRCRAFT, THIS EO IS BEING ISSUED TO PROVIDE INSTRUCTIONS FOR THE ON
CONDITION REPAIR OF CORRODED OR DAMAGED FWD CARGO (FWD AND AFT FINGER DOUBLERS) BY PART REPLACEMENT
(TABLE 2). THE REPLACEMENT IS ACCOMPLISHED USING THE EMBRAER PRODUCTION DRAWINGS AND SRM CHAPTER 51
PROCEDURES. SINCE THE DAMAGED STRUCTURE IS BEING REPLACED WITH NEW PARTS PER THE PRODUCTION DRAWINGS, THE AIRCRAFT
STRUCTURE REMAINS IN ITS ORIGINAL CONFIGURATION; NO CHANGES TO THE EXISTING INSPECTION PROGRAM ARE REQUIRED.W.O.2739004467
