At least four separate flights encountered technical issues or emergencies within days of the Ahmedabad Air India crash, forcing sudden flight diversions and raising fresh concerns.

NEW DELHI (Reuters) -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.

The Air India flight fell from the sky on Thursday and killed at least 270 people in Gujarat state, officials said Saturday.

The crash of a Boeing 787 passenger jet in India minutes after takeoff on Thursday is the latest incident that adds to woes at the troubled U.S. planemaker.

The crash happened just weeks after the company cut a deal with the U.S. government to avoid taking criminal responsibility for a pair of deadly crashes in 2018 and 2019.

An Air India crash Thursday involved a Boeing 787-8 Dreamliner, which the aircraft manufacturer first delivered 14 years ago.

Indian authorities have ordered what they called “extended surveillance” of all Boeing 787 aircraft in the country’s fleet while they investigate the cause of the Air India crash.
