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.

Air India flight AI171, a Boeing 787-8 carrying 242 people, crashed after taking off from Ahmedabad on its way to London.

It could take months to fully understand what went wrong in the crash, the first involving a Dreamliner. Officials from India continued the investigation Friday.

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.

The event, which runs from June 16 to June 20, is the industry's largest trade show, where many aircraft orders are typically placed by airlines.

Boeing Co. Chief Executive Officer Kelly Ortberg finds himself in a painfully familiar role as he faces another crisis, this time over a crash involving the company’s marquee 787 Dreamliner jet in India that killed more than 240 people.

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.

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.

President Donald Trump swiftly addressed the incident, calling it “terrible” and “one of the worst in aviation history.” He said the US was ready to provide any necessary assistance, stating, “Anything we can do, we’ll be over there immediately.”
