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.

Boeing stock was wavering on Tuesday as investors awaited more information about the 787 crash in India.Shares of the commercial jet maker gained 0.2% to $202.09 in midday trading, while the S&P 500 and Dow Jones Industrial Average fell 0.

India’s aviation safety regulator has said it has found no “major safety concerns” during inspections of Air India’s Boeing 787 aircraft following Thursday’s fatal crash of a flight from Ahmedabad to London.
