At least four separate flights encountered technical issues or emergencies within days of the Ahmedabad Air India crash, forcing sudden flight diversions and raising fresh concerns.

In the wake of the tragic crash of AI-171—a Boeing 787-8 Dreamliner that exploded into flames moments after take-off from Ahmedabad—Air India has cancelled six international Dreamliner services on Tuesday. The cancellations, involving the same aircraft model, come amid heightened scrutiny of Boeing's flagship 787 series.

All but one of the 242 souls aboard the Boeing Dreamliner 787 perished in the crash, and more than three dozen were killed on the ground.

Both flight data and cockpit voice recordings are crucial to piece together the sequence of events that led to the fatal crash.

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

The accident happened just weeks after the company cut a deal with the U.S. government to avoid taking criminal responsibility for a pair of deadly crashes in 2018 and 2019.
