## Discrepancy

AFTER ENGINE SHUTDOWN, WHITE SMOKE(FUEL VAPOUR) ERUPTED FROM EXHAUST NOZZLE. TECHNICIAN NOTICED IT AND MADE A TEST RUN, FOUND THAT FIRE OUT OF EXAUST NOZZLE AND LH ENGINE WAS NOT ABLE TO BE SHUTDOWN BY PULLING BACK THROTTLE LEVER, . FINALLY AFT THROTTLE CABLE OF LH ENGINE WAS FOUND TOTALLY BREAKEN AT PYLON FIREWALL POSITION, THERE IS NO SIGNS OF WEAR ON THROTTLE CABLE, IT SEEMS LIKE FATIGUE BREAK.
