Simulation of Crashed Air India Jet Puts Focus on Technical Flaw

More than two weeks after the deadly crash of an Air India plane that killed all but one of the 242 people on board, investigators and the airline are studying possible dual engine failure as a scenario that prevented the Boeing Co. 787 jet from staying airborne.

Pilots from the airline reenacted the doomed aircraft’s parameters in a flight simulator, including with the landing gear deployed and the wing flaps retracted, and found those settings alone didn’t cause a crash, according to people familiar with the investigation.
