An Air India A320 cruising at 36,000 feet experienced a rare cascading hydraulic system failure (all three systems lost within 4 seconds) on an August 4 flight from Phuket to New Delhi, triggering a stall warning and violent pitch movements that injured 24 passengers. The incident was triggered while seatbelt signs were off. Investigators found the captain tested non-negative for psychoactive substances, adding to scrutiny following Air India's fatal 2025 Boeing 787 crash. India is now considering mandatory annual drug testing for all pilots, and Airbus has flagged the systemic hydraulic loss as a serious concern requiring priority regulatory action.
