## Discrepancy

INFLIGHT, BROUGHT BACK THE THRUST LEVERS TO IDLE, THE LANDING GEAR INTRANSIT RED LIGHT AND CONFIG HORN CAME ON.  COULD SILENCE WITH HORN CANCEL BUTTON.  ONLY HAPPENED WITH GEAR UP.  ALL CONDITIONS NORMAL WITH GEAR DOWN.  REMOVED AND REPLACED ADAU, P/N ON/OFF HC396H0485-008, S/N ON ULT-0097-98, S/N OFF ULT-010-98.  ALL CHECKS GOOD.
