An Air Canada flight bound for Paris on Jun 5 experienced an alleged ‘compressor stall‘ on departure from Canada’s busiest airport. AC872 had just taken off from Toronto Pearson International Airport (YYZ) runway 23, bound for the French capital, Paris Charles de Gaulle (CDG). Loaded with 400 passengers, the flight on Wednesday night quickly returned to the ground in Toronto, where emergency services and maintenance teams met it. Passengers were re-accommodated onto an alternative aircraft, and there were no reports of any injuries sustained onboard.
