Keystone Air Suspended by Transport Canada

After a Keystone Air flight crash-landed near Thompson, Manitoba, Transport Canada has suspended the airline's operating certificate.

Global News reached out to the airline early Tuesday morning but the company was not available for comment.

Transport Canada suspended Keystone Air on October 9, which prohibits the company from providing commercial air service.

"Keystone Air Services posed an immediate and significant threat to aviation safety, Transport Canada took swift and firm action to protect the public." said Transport Canada.

Keystone Air Service, which has been flying since 1985, may not resume commercial air service until it demonstrates to Transport Canada that it is in full compliance with aviation safety regulations.

Transport Canada said the companies day-to-day safety operations were not in compliance with safety regulations, for example, training of pilots and ensuring unsafe aircrafts stay on the ground.

Keystone Air crashed near the Thompson airport Sep. 15, 2015 - sending eight people to hospital including six government workers. The wrong fuel was said to be put in the plane.

"most of them have gone through some very serious trauma," said Premier Greg Selinger, who recently met with the staff, "some have had physical injuries some have had post traumatic stress disorder."

Back in January 2012, a Piper Navajo -- also operated by Keystone Air Service -- crashed near a remote Northern Ontario community killing four people after it departed Winnipeg.

The pilot and three passengers were killed; one other passenger survived.

And in 2002, a Keystone flight crash landed on a Winnipeg street after it ran out of fuel. One person died from their injures.
