An Air India crash Thursday involved a Boeing 787-8 Dreamliner, which the aircraft manufacturer first delivered 14 years ago.

Air India and Boeing are in the midst of significant turnarounds, but knowing the cause of the crash of Flight 171 will take a lengthy investigation.

Only one passenger onboard the aircraft survived in the tragic accident. These checks are being carried out on the Boeing 787 fleet as they return to India, before being cleared for their next operations, Air India said.

It could take months to fully understand what went wrong in the crash, the first involving a Dreamliner. Officials from India continued the investigation Friday.

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

It’s also the latest disaster to hit the beleaguered American aerospace giant — which has been dogged by a door that blew off a 737 jet, a leaky spacecraft that stranded astronauts on the International Space Station for months, as well as politically damaging delays in outfitting the new Air Force One jets.
