The Air India 787 went down in the north-western city of Ahmedabad with more than 240 people aboard shortly after take-off, authorities said.

This was the first deadly accident since the Dreamliner, as the plane is also called, began flying in 2009, according to data from the Aviation Safety Network.

Boeing shares fell more than four per cent in afternoon trading.

The 787 was notable as the first airliner to extensively utilize lithium-ion batteries, which are lighter in weight, recharge more quickly, and can store more energy compared to other battery types.

In 2013 the 787 fleet was temporarily grounded because of overheating of its lithium-ion batteries, which in some cases sparked fires.

The Max version of Boeing’s best-selling 737 airplane has been the source of persistent troubles for Boeing after two of the jets crashed.

The crashes, one in Indonesia in 2018 and another in Ethiopia in 2019, killed 346.

The issue originated from a sensor giving incorrect readings that forced the nose downward, making it impossible for pilots to regain control. Following the second crash, Max jets were grounded worldwide until a redesign of the system by the company was completed.

Last month, the Justice Department reached a deal to allow Boeing to avoid criminal prosecution for allegedly misleading US regulators about the Max before the two crashes.

Worries about the plane flared up again after a door plug blew off a Max operated by Alaska Airlines, leading regulators to cap Boeing’s production at 38 jets per month.

Boeing posted a loss of $US11.8 billion ($18 billion) in 2024, bringing its total losses since 2019 to more than $US35 billion ($53.6).

The company’s financial problems were compounded by a strike by machinists who assemble the airplanes plane at its factories in Renton and Everett, Washington, which halted production at those facilities and hampered Boeing’s delivery capability.

For the first three months of 2025, Boeing reported a narrower loss of $US31 million ($47.5 billion) compared with the previous year. CEO Kelly Ortberg said Boeing made progress on stabilising operations during the quarter.

The stepped-up government scrutiny and the workers’ strike resulted in Boeing’s aircraft deliveries sliding last year.

Boeing said it supplied 348 jetliners in 2024, which was a third fewer than the 528 that it reported for the previous year.

The company delivered less than half the number of commercial aircraft to customers than its main rival Airbus, which reported delivering 766 commercial jets in 2023.

Still, Boeing’s troubles haven’t turned off airline customers from buying its jets.

Last month the company secured big orders from two Middle Eastern customers.

The deals included a $US96 billion ($147 billion) order for 787 and 777X jets from Qatar, which it said was the biggest order for 787s and wide body jets in the company’s.
