The black boxes will provide cockpit conversations and data related to the plane's engine and control settings to investigators and help them in determining the cause of the crash.

The crash could renew scrutiny of Boeing, which suffered a major blow to its reputation after 2018 and 2019 crashes involving its 737 Max planes.

India's aviation safety watchdog said on Tuesday surveillance conducted on Air India's Boeing 787 fleet did not reveal any major safety concerns, days after one of its jets crashed, killing at least 271 people.
