Shares of planemaker Boeing fell as much as 8% in premarket U.S. trading on Thursday after an Air India aircraft with 242 people crashed minutes after taking off from India's western city of Ahmedabad.
Aviation tracking site Flightradar24 said the plane was a Boeing 787-8 Dreamliner, one of the most modern passenger aircraft in service.
The plane was headed to Gatwick Airport in the U.K., Air India said, while police officers said it crashed in a civilian area near the airport, without specifying whether there were any fatalities.
It was not immediately clear what caused the crash. Boeing said in a statement it was aware of initial reports and was working to gather more information.
The news comes as the planemaker tries to rebuild trust related to safety in its jets and ramp up production under new CEO Kelly Orthberg.
Boeing's shares were down about 8% at $196.52 in premarket trading.
"It's a knee-jerk reaction (to the incident) and there's revised fears of the problems that plagued Boeing aircraft and Boeing itself in recent years," said Chris Beauchamp, analyst at IG Group.
