Toronto-bound Air Canada flight due to make emergency landing in Madrid

An Air Canada flight bound for Toronto is set to make an emergency landing in Madrid on Monday after experiencing engine issues shortly after taking off.

Flight AC837 was travelling from Madrid to Toronto with 128 passengers on board, Air Canada said in a statement.

Along with the engine issues, Air Canada's statement said a tire also reportedly ruptured on takeoff. The tire is one of 10 on the plane.

"The aircraft, a Boeing 767-300, is designed to operate on one engine and our pilots are fully trained for this eventuality," Air Canada said.

"Nonetheless, an emergency was declared in order to obtain landing priority."

Request for emergency landing 30 minutes after takeoff

Spain's port operator AENA says the aircraft departed from the Adolfo Suarez-Barajas international airport earlier in the day.

An AENA spokesperson said the airline had requested a slot for an emergency landing some 30 minutes after the takeoff. The official, who was not authorized to be named in media reports, said the she couldn't elaborate.

Spain's main union of pilot workers, SEPLA, said in a tweet that the plane lost some pieces of its landing gear during takeoff and that the aircraft needs to fly in circles to burn off fuel before landing.

Citing airport sources, Spain's El Mundo newspaper reported that the plane lost a wheel during takeoff.

Madrid residents posted videos online showing a plane flying unusually low over the Spanish capital's centre and suburbs.
