The head of Boeing Commercial Airplanes, Stephanie Pope, met the chairman of Air India on Monday in India, two sources said, as the companies seek to find the cause of last week's fatal crash involving a Boeing 787 Dreamliner.

At least 270 died when the Air India flight crashed into the campus of a medical college in Ahmedabad shortly after takeoff on Thursday.

Boeing shares fell more than 4% in afternoon trading.
