Mid-Flight Change of Plans
Eight hours into its flight, while cruising at an altitude of 33,000 feet over the Black Sea, the decision was made to turn the aircraft around. The crew proceeded to fly nearly four additional hours, ultimately diverting to London Heathrow Airport due to an unexpected maintenance issue. The aircraft conducted a fuel dump at FL320 before beginning its approach to the airport.
Landing and Flight Cancellation
The Boeing 777-200LR landed safely on runway 27L at London Heathrow and reached gate B36. The total flight time was 12 hours and 38 minutes. Following the diversion, passengers disembarked without incident.
Due to unresolved maintenance concerns—potentially related to electrical or hydraulic components—the airline cancelled the flight. Air Canada stated that the necessary repairs would require more time than could be accommodated by a reasonable flight delay.
