## Discrepancy

DURING APPROACH, THE T/E FLAPS ASYMMETRY LIGHT TURNED ON WHEN FLIGHT CREW SELECTED FLAPS 5 GRADE, DISCONNECTING THE YAW DAMPER; SO THE FLIGHT CREW PERFORMED THE QRH 9.28 AND 9.40 PROCEDURES, LANDING WITH T/E FLAPS UP. DURING MX REVISION, THE FIM PROCEDURES 27-51 TASKS 801, 836 AND 847;  27-81 TASK 806 IN FSEU WERE PERFORMED AND THE FAILURE CODE WAS NOT PRESENTED AND AS A PRECAUTIONARY ACTION, THE T/E FLAPS BY PASS VALVE WAS REPLACED IAW MM 27-51-02. DURING OVERNIGHT CHECK WAS DETECTED 27-52260 CODE IN THE FSEU; SO THE RIGHT FLAPS POSITION TX WAS REPLACED IAW MM 27-58-01; ALSO THE FIM PROCEDURES 27-51 TASK 801; 27-88 TASK 820 AND 27-51 TASK 836 WERE PERFORMED, ALL CORRECT.
