About 100 of the 307 people onboard the plane during the crash landing last summer have joined the lawsuit, the Chicago Tribune reported. It was filed Friday in Cook County Circuit Court in Chicago.
In their complaint, the plaintiffs charge Boeing knew the airspeed warning systems and auto-throttle controls on the 777 jet were not adequate and the pilots not properly trained.
Three people were killed when the plane, landing at San Francisco International Airport after a flight from Seoul, hit a seawall. Other lawsuits have already been filed.
