Just days apart, two separate incidents involving Air India's Boeing 787 Dreamliner aircraft have put the spotlight firmly on the airline's operations and, more broadly, on the reliability of this popular wide-body jet.

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 deadly crash of Air India Flight 171 last week has centered renewed scrutiny on the airplane's manufacturer, Boeing, and this time it's the 787 Dreamliner in investigators' sights. The accident, which killed over 270 people, was the first fatal crash for the Dreamliner since the model began flying in 2011.
