UPDATE: TSB Report #A21P0117: C-GUAJ, a Cargojet Airways Ltd. Boeing 767-300, was operating as CJT555 from Edmonton Intl, AB (CYEG) to Vancouver Intl, BC (CYVR) with pilots on board. While on descent into CYVR, the flight crew saw a MAIN CARGO FIRE annunciation on the Engine Indicating and Crew Alerting System (EICAS), as well as fire warnings and the fire bell. When the Master Warning was cancelled, all other indications of a fire ceased. The flight crew advised air traffic control of the main cargo fire warning and that it had extinguished, but requested priority handling and the Aircraft Rescue and Fire Fighting (ARFF) unit on standby as a precaution. The airplane was stopped on the runway to have ARFF personnel inspect for any signs of smoke or fire. Once given the all-clear, fire vehicles escorted the flight to the ramp. Company maintenance determined that this defect appeared to have some history and there was ongoing troubleshooting. They discovered an electrical short circuit in the wiring between the loop 1 main alarm and the loop 2 main alarm.
