Plaintiffs lawyers with expertise in airplane crash litigation predict that most of the lawsuits over the Asiana Airlines crash will name both the airline and The Boeing Co., which manufactured the aircraft. Although the first lawsuit was filed on July 15, most plaintiffs attorneys are investigating the roles that Boeing or other manufacturers of the plane and its components may have played in the crash. That’s because, under an international treaty, most of the passengers aboard Asiana Airlines Flight 214 could be barred from suing the South Korean airline in U.S. courts.

But all passengers, regardless of their nationalities, could bring claims in U.S. courts against Boeing, based in Chicago, or any number of unnamed U.S. subcontractors that had a hand in the plane’s manufacture.
