**New Delhi: **A preliminary investigation by the Aircraft Accident Investigation Bureau into an incident involving an Air India flight from Phuket to Delhi has found that a sudden failure of the aircraft’s hydraulic systems contributed to a significant loss of altitude during the flight. The preliminary report has also raised concerns over the conduct of the pilot who was operating the aircraft at the time of the incident.

> The Airbus A320neo was flying at an altitude of around 36,000 feet when all three of its hydraulic systems reportedly became inoperative within a matter of seconds. According to the investigation, the sudden loss of hydraulic functionality resulted in an “altitude upset”, a condition involving an unexpected deviation in an aircraft’s altitude or flight attitude. There were 137 passengers on board the aircraft at the time.

The report states that the pilot in command did not directly handle the primary flight controls during the incident. It also notes that the results of two tests conducted on the co-pilot were negative.

In addition to examining the technical problems faced by the aircraft, the investigation has highlighted concerns relating to compliance with aviation safety standards. The investigation team has recommended strict action against the pilot if the findings regarding the pilot’s conduct are established through the appropriate regulatory process.

The report has also called for urgent action by the Directorate General of Civil Aviation (DGCA) over the alleged serious lapse on the part of the pilot. The findings are expected to draw further attention to cockpit safety, crew fitness requirements and the importance of maintaining strict operational standards in commercial aviation.

The incident has once again highlighted the critical role of aircraft hydraulic systems in maintaining flight-control functionality and the need for immediate and effective responses when multiple aircraft systems fail simultaneously.

As the investigation progresses, aviation authorities are expected to examine both the technical failure and the human factors associated with the incident before determining final responsibility and any regulatory action.
