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 Thursday’s crash of an Air India plane.

India’s government is urgently inspecting all Boeing 787s after a devastating Air India crash that claimed at least 270 lives this week, the aviation minister said on Saturday, adding that the authorities were investigating all possible causes.

As the investigation continued Friday into the horrific Air India Boeing 787 Dreamliner crash that killed at least 290 people, the sole survivor is doing well but is "psychologically disturbed."

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.

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.

The crash in India of a Boeing 787-8 passenger jet carrying 242 people bound for London has resurfaced concerns about safety in the skies. WSJ's Andrew Tangel answers audience questions over the crash and aviation safety.

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.
