A post-flight maintenance report of Air India Phuket-Delhi flight AI2379 on August 4, 2026, which suffered a sudden altitude loss on August 4, has flagged multiple warnings involving faults in the aircraft’s hydraulic and flight-control systems. The maintenance report reviewed by businessline showed that the Airbus A320neo, registered VT-EXO, recorded repeated warnings of low pressure in its hydraulic systems. Around the same time, the aircraft recorded a fault involving the left and right elevators. However, the maintenance report does not establish whether these warnings were linked to the sudden loss of altitude. It also does not indicate whether the hydraulic warnings were caused by an actual loss of pressure or fluid.
