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.

The assurance comes even as more than 66 Air India flights scheduled to operate with the Dreamliner aircraft were cancelled.

Aviation watchdog DGCA on Tuesday said surveillance of Air India’s Boeing 787 fleet did not reveal any major safety concerns in the wake of the fatal plane crash in Ahmedabad last week

In response to heightened safety concerns, DGCA confirmed that comprehensive surveillance of Air India’s Boeing 787 Dreamliner fleet revealed no significant safety deviations.

The head of Boeing Commercial Airplanes, Stephanie Pope, met the chairman of Air India on Monday in India, two sources said, as the companies seek to find the cause of last week's fatal crash involving a Boeing 787 Dreamliner.

The investigation into Air India flight 171 crash opens up questions into the many concerns surrounding Boeing's 787.

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.
