Air India crash latest: Investigators find emergency power likely came on before crash as 66 Dreamliner flights cancelled

Indian aviation regulator finds no major safety flaws in Air India Dreamliners but flags maintenance and coordination issues.

Investigators probing the deadly crash of Air India flight 171 in which more than 270 people were killed have found that the aircraft’s emergency power system was likely active just before impact.

The Wall Street Journal reported that this possibly suggested an engine or hydraulic failure during takeoff, a rare and serious event in commercial aviation.

However, the investigators were yet to determine whether engine, hydraulic, or other system failures activated the emergency power, according to the outlet, which cited people familiar with the probe.

Air India has cancelled 66 Dreamliner flights since the 12 June crash in Ahmedabad, Indian aviation regulator DGCA said on Tuesday.

The airline has also delayed multiple flights serviced by Boeing 787-8. It has attributed the interruptions to grounded aircraft, technical issues, restricted airspace, and heightened safety protocols.

The DGCA, meanwhile, has found no major flaws in Air India’s Dreamliners, but flagged maintenance delays and coordination issues.
