An investigation into an A320neo flight incident reveals that the aircraft experienced a rare, near-simultaneous failure of all three hydraulic systems at 36,000 feet. The report confirms the event caused an altitude upset and injuries, though the root cause remains under investigation.
Why it matters
This incident is significant for aviation safety, as the loss of all hydraulic systems is considered a critical failure that challenges standard flight control protocols.
MUMBAI: Aircraft Accident Investigation Bureau's preliminary report has confirmed what pilots and engineers call an exceptionally rare event, the near-simultaneous loss of all three hydraulic systems on the A320neo aircraft at 36,000 feet. Hydraulic systems are the fluid-pressure circuits that physically move an aircraft's wing and tail surfaces. The green, blue and yellow systems dropped out within seconds of each other, triggering an autopilot disengagement, a stall warning and a brief altitude upset that injured 24 flyers.The accident occurred when the eight-year-old A320neo (VT-EXO) carrying 145 people had just been cleared to climb from 34,000 feet to 36,000 feet after entering the airspace controlled by Kolkata ATC.
