Air India A320's Mid-Air Ordeal: Rare Hydraulic Failure Shakes Global Aviation Safety

An Air India Airbus A320, flight AI2379 from Phuket to Delhi, plunged 300 feet on August 4, 2026, after suffering a 'rarest of rare' simultaneous failure across all three of its independent hydraulic systems. This critical malfunction left pilots without control of essential flight surfaces for approximately four seconds, injuring 24 people onboard and triggering a high-stakes international investigation. Airbus's initial assessment of the flight data recorder confirms the multiple hydraulic system losses, impacting the aircraft's elevators and ailerons, which are crucial for stable flight. This incident comes amid revelations that the pilot-in-command tested positive for marijuana and reportedly admitted to struggling with sleep, even sleeping mid-flight. While investigators have not yet linked the pilot's condition to the technical failure, Air India has swiftly responded by mandating psychoactive substance screening for all its pilots, exceeding existing regulatory requirements. India's Aircraft Accident Investigation Bureau (AAIB), with technical support from Airbus and France's BEA, is deeply probing the simultaneous hydraulic system failure to determine if it was a genuine mechanical defect or a faulty sensor signal. The findings will have significant implications not just for Air India but for global aviation safety standards and the widely used A320 fleet, prompting calls for tougher pilot fitness regulations.
