Air India flight had all three hydraulic systems fail: controls did not respond for four seconds, plane dropped 300 feet; 24 injured
Airbus's preliminary probe says an Air India Phuket-Delhi flight briefly lost control after all three hydraulic systems failed, injuring 24 people.
Intelligence analysis by GPT-5.4 Mini

A preliminary Airbus finding shifts the Air India Phuket-Delhi incident away from turbulence and toward a technical failure. The report says all three hydraulic systems failed one after another, leaving the aircraft without control for about four seconds.
A plane is like a huge bike with many parts that help it turn and stay steady. On this flight, the parts that help control it stopped working for a few seconds, so it dropped fast and some people got hurt.
Analysis
Airbus A320
The most important part of this report is not the drop itself, but the explanation for it. Airbus's early finding points to a technical failure on an Air India A320 rather than the turbulence-based explanation that Air India first gave.
That matters because it changes the story from a weather problem into a systems problem. When a manufacturer says the aircraft's behavior came from a mechanical chain reaction, it raises the stakes for maintenance checks, fault analysis, and how quickly crews can diagnose a cascading failure in real time.
Three Hydraulic Systems
The article says the aircraft's three hydraulic systems failed one after the other, which is what left the elevators and ailerons without normal response for about four seconds. In a passenger jet, those surfaces are what let pilots pitch and roll the plane, so a brief failure can still create a violent, sudden motion.
That detail also explains why the incident was treated as more than ordinary rough air. If the spoiler system was also affected, then the crew was dealing with a much wider control problem than a simple bump in the sky. The source says the root cause has not yet been identified, which means the most important technical question is still open.
Bhubaneswar
The aircraft was flying from Phuket to Delhi when the incident happened near Bhubaneswar, and the sudden drop injured 20 passengers and four crew members. The article says some injured passengers were taken out on stretchers, which suggests the force of the event was strong enough to produce real physical harm, not just alarm.
The earlier suspicion that the pilot may have been intoxicated now sits awkwardly beside the new technical finding. That shift does not end the inquiry, but it does show how aviation accidents often move through competing explanations before the evidence settles on a cause. For Air India, the larger issue is trust: passengers will want to know whether this was a one-off failure or a sign of a deeper systems weakness.
Key points
- Airbus's preliminary check says the incident was caused by a technical failure, not turbulence.
- The article says all three hydraulic systems failed one after another.
- The control surfaces did not respond for about four seconds, and the plane dropped sharply.
- The flight was from Phuket to Delhi and the incident happened near Bhubaneswar.
- Twenty passengers and four crew members were injured, while the root cause is still unknown.
If the technical-failure finding holds up, investigators can focus on the aircraft and its maintenance history instead of chasing the wrong explanation. That could lead to stronger safety checks and better fault detection on similar planes. A clearer answer may also help restore confidence, because passengers and regulators will know what actually went wrong and what needs fixing.
If the root cause stays unknown, the same kind of failure could be hard to prevent on future flights. That would leave airlines with an uncomfortable gap between what happened and what they can do to stop it happening again. The conflicting early explanations also risk slowing accountability and keeping public trust under pressure.
