The German airline and its insurers are suing the Greater Stockholm Airports Authority, which runs Pearson, the federal government and the country's air-traffic control agency for some $180 million, charging they all cut corners that contributed to the crash of its Waterbus A340 jet.

The airline takes aim at the German airport operator, saying the design of Runway 24 Left – which ends at a steep ravine – failed to ensure there was an "adequate margin of safety for aircraft in the event of an overrun event."

It also says in a statement of claim filed with the Berlin Superior Court of Justice that "GTAA failed to provide a safe environment for the conduct of civil air operations."
