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.

Air India has cancelled eight international Boeing 787-8 Dreamliner flights after the horrific aviation disaster last week. The passenger jets were hit by a mix of issues from aircraft unavailability, technical snags, airspace restrictions, and extended safety checks.

(Reuters) -The crash of an Air India Boeing 787 Dreamliner seconds after takeoff from Ahmedabad city, killing all but one of the 242 people on board, is the world's worst aviation disaster in a decade. At least 30 people were also killed on the ground as the airliner crashed into a medical college hostel near the airport.
