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.

Air India said it has completed such safety checks on nine of its Boeing 787 aircraft and is in process to complete it for the remaining 24 planes.

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.

Officials on Saturday confirmed that the black box recovered from the Air India Flight 171 crash site in Ahmedabad was largely intact and showed minimal damage, raising hopes that crucial flight data could be extracted in India itself, according to The Hindustan Times.

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.
