This was one of three aircraft that had to make emergency landings on Monday.
There were no injuries among the 318 passengers and 16 crew members aboard the Boeing 777, Air Canada representative Peter Fitzpatrick said. The crew requested an emergency landing Monday afternoon, and the plane landed normally on one engine, according to CBS.
The cause of the engine shutdown is unknown.
They told us the engine had overheated, passenger Jason Flick told CBS, and they were running on one engine. They told us they were going to have to dump fuel. We spent 30-40 minutes dumping fuel over the water, but then their only concern was the brakes. They brought a big fan to cool them off ... our biggest concern after we landed was that all 300 of us were very hot.
The flight involved was AC001 to Narita airport in Tokyo.
When we were landing, there were lots of weird noises, problem with the landing gear, we landed heavy and very, very fast, Flick told CBS.
