Canadian investigators have disclosed that an Air Canada Airbus A321 proceeded to land at Toronto despite being instructed to execute a go-around.
The aircraft had been operating flight AC150 from Calgary on 18 August, states the Transportation Safety Board of Canada.
It had been approaching runway 06L, on short final, when air traffic control ordered it to conduct a go-around owing to a preceding aircraft not having vacated the runway.
“The go-around transmission was not acknowledged by the flight crew of [the A321] and the aircraft proceeded with the landing,” says the safety board.
It landed and exited the runway without further incident, with no injuries among the 196 occupants.
At the time of the incident, given as 21:50, the approach would have been conducted in darkness.
