The first lawsuits have been filed against The Boeing Co., manufacturer of the Asiana Airlines jet that crashed on July 6 while landing at San Francisco International Airport.

The first two lawsuits brought over the crash, which killed three passengers and injured about 180 others, were filed against Asiana Airlines Inc. in federal court in San Francisco on behalf of three passengers of Flight 214. Residents of the United States, and foreign passengers who purchase their tickets in the United States or whose final destination is the United States, are entitled to damages against Asiana, based in South Korea, under an international treaty called the 1999 Montreal Convention. Each of the suits, filed by Bowles & Verna in Walnut Creek, Calif., seeks $5 million.
