For what it's worth, in Canada it would be harder to prove liability on the part of Cessna than in the US. Years ago American courts adopted a standard of strict liability in products liability cases, which makes it much easier for plaintiffs to recover in the event of an accident like this one. In Canada in the event of a lawsuit the plaintiffs would have a much more difficult time of it, given the current state of the law which requires a plaintiff to prove negligence on the part of the manufacturer.
