# Air India A320 lost all controls for 4 seconds after triple hydraulic failure 2026-08-14T11:10:47+00:00 | Governance | Indian Opinion Desk Corroboration: 3 independent outlets An Airbus A320neo operating Air India flight AI2379 from Phuket to Delhi on August 4 temporarily lost the use of its elevators and ailerons for nearly four seconds after all three hydraulic systems failed in quick succession, according to a preliminary Airbus assessment reviewed by Reuters. The aircraft dropped about 300 feet (91 metres) and 24 people were injured before hydraulics recovered and pilots landed safely in Delhi. India's Aircraft Accident Investigation Bureau (AAIB) is investigating, with technical help from Airbus and France's BEA. The cause of the pressure losses remains unknown. Airbus has asked Air India to test hydraulic systems, sensors and wiring and inspect for structural stress. Separately, the captain tested positive for marijuana in a confirmatory drug test, but authorities say no link has been established to the technical event. ## Coverage - indiatvnews.com - airdatanews.com - english.mathrubhumi.com Tags: AAIB, Air India, Airbus A320, DGCA Canonical: https://indianopinion.org/air-india-flight-lost-all-controls-for-4-seconds-after-triple-hydraulic-failure/ License: Summary and commentary (c) Indian Opinion, reusable with attribution.
