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.

The Air India plane that crashed in Ahmedabad on June 12 was a Boeing 787 Dreamliner aircraft. As per a report, Air India had 34 Boeing 787 airframes in its fleet before the crash.

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

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.
