It’s estimated that pulling the planes from the runway will cost SAS up to US$62 million for the rest of the year.
The grounding comes after a series of incidents caused by landing gear malfunctions. Plane manufacturer Bombardier are refusing to comment on the decision by SAS, but add that many other airlines have been using the planes, without problems.
But Claude Proulx, an analyst at BMO Capital Markets told news agency Reuters that the problems might be specific to SAS because of the type of conditions in which the aircraft are operated by the airline, such as frequent flights over salt water in a cold climate.
