4 Seconds of No Control on Phuket-Delhi Air India Flight: All 3 Hydraulics Failed Mid-Air, Airbus Confirms

Airbus analysis of the Digital Flight Data Recorder reveals that Air India flight AI2379 briefly lost all three hydraulic systems—green, blue, and yellow—and critical flight controls for approximately four seconds. This failure occurred during a 300-foot altitude drop on August 4 during a Phuket-Delhi flight. Investigators are currently scrutinizing a faulty green hydraulic pressure switch as the cause. The incident involved an A320 aircraft, with the findings shared in an initial report sent to Air India.
