A crashed Lion Air jet should have been grounded over a recurrent technical problem before its fatal journey, Indonesian authorities said Wednesday, as details from the new jet's flight data recorder suggested that pilots struggled to control its anti-stalling system.

The preliminary crash report from Indonesia's transport safety agency also took aim at the budget carrier's poor safety culture, but did not pinpoint a definitive cause of the October 29 accident, which killed all 189 people on board. A final report is not likely to be filed until next year. The Boeing 737 MAX vanished from radar about 13 minutes after taking off from Jakarta, slamming into the Java Sea moments after pilots had asked to return to the capital.
