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.

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

An Air India Boeing 787-8 flight headed for New Delhi returned to Hong Kong shortly after takeoff Monday because of a "technical issue," Indian media reported.
