## Discrepancy

AIRCRAFT RETURNED OF FLIGHT DUE TO DURING CLIMB, THE LEFT FIRE DETECTION SYSTEM FAULT LIGHT TURNED ON. MAINTENANCE PERSONNEL PERFORMED LEFT ENGINE FIRE DETECTION TEST IAW AMM 26-10-00, DETECTING LOOP B OF LEFT ENGINE WITH FAULT; SO THE CIRCUIT BREAKERS A24, A21 ON PANEL P6-2 WERE RESEATED IAW AMM 26-11-00 AND THE WIRING IN CONNECTOR DJ2501 WAS FIXED IAW WDM 26-11-11 AND BOTH CORE FIRE DETECTOR WERE REPLACED IAW AMM 26-11-01, TESTED CORRECT.
