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

An Air India plane bound for London Gatwick Airport crashed shortly after take-off on June 12 in Ahmedabad, western India. Flight AI171 was carrying 242 people, including 169 Indian nationals, 53 Britons,

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.

It’s also the latest disaster to hit the beleaguered American aerospace giant — which has been dogged by a door that blew off a 737 jet, a leaky spacecraft that stranded astronauts on the International Space Station for months, as well as politically damaging delays in outfitting the new Air Force One jets.

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.

Investors are looking for answers regarding the Air India Boeing 787 that crashed Thursday, killing more than 240 people.

Air India and Boeing are in the midst of significant turnarounds, but knowing the cause of the crash of Flight 171 will take a lengthy investigation.

Last year, the F.A.A. said it was also investigating claims by a Boeing engineer that parts of the fuselage, or body, of the Dreamliner were improperly fastened together, which the whistle-blower said could cause premature damage to the plane over years of use.

The Air India flight, carrying 242 passengers and crew members, crashed shortly after takeoff from Ahmedabad, India, en route to London Gatwick.

An Air India flight was forced to turn around and return to Hong Kong after an unspecified technical issue was discovered with the aircraft. The Boeing 787-8 Dreamliner— the same craft involved in last week’s devastating crash in Ahmedabad which killed 270 people—was an hour into a flight to New Delhi when the pilot suspected a problem and turned around.
