Air India Flight AI2379 Logs Multiple Warnings During Turbulence Incident

Chandigarh, India Aug 13, 2026 ALN: A recent incident involving an Air India flight from Phuket to Delhi has raised serious safety concerns after the aircraft logged multiple warnings during a turbulent descent. Flight AI2379, an Airbus A320, reported nine critical warnings in a single minute, indicating significant issues with its hydraulic systems and autopilot functionality.

The incident occurred on August 4, when the aircraft unexpectedly lost altitude, dropping approximately 300 feet and injuring 24 individuals on board, including 20 passengers and four crew members. Following the event, the Aircraft Accident Investigation Bureau (AAIB) initiated an investigation to determine the cause of the turbulence and the subsequent warnings. This investigation is crucial as it aims to uncover not only the immediate factors that led to the incident but also any underlying systemic issues that could affect future flights.

According to the Centralised Fault Display System log, the warnings included low pressure in the aircraft's hydraulic systems, specifically the Green, Blue, and Yellow systems, as well as a disconnect of the autopilot and an elevator flight-control fault. These warnings were recorded shortly after the aircraft crossed the Odisha coast, indicating a potential mechanical failure during flight. The hydraulic systems in an aircraft are essential for various critical functions, including controlling the movement of the ailerons, elevators, and rudders, and any failure in these systems can pose a significant risk to flight safety.

Details of the Incident

The log revealed that the warnings appeared at 9:32 AM IST, shortly after the aircraft had been flying over the Bay of Bengal. The warnings indicated low reservoir levels in the Yellow and Blue hydraulic systems, which are critical for the aircraft's operation. Notably, the hydraulic systems rely on pressurized fluid to function effectively, and any disruption can lead to severe operational issues. The fact that multiple hydraulic warnings were logged in quick succession suggests a potential cascading failure that could have jeopardized the safety of the flight.

In addition to the hydraulic warnings, two emergency-exit door sensor warnings were logged shortly thereafter. However, no further warnings related to the hydraulic systems or elevator were recorded for the next 43 minutes, suggesting a temporary issue rather than a sustained mechanical failure. This intermittent nature of the warnings raises questions about the reliability of the aircraft's systems and whether there might be a need for further investigation into the aircraft's maintenance history and operational protocols.

At 10:16 AM, an engine anti-ice fault was noted, followed by another autopilot disconnect at 10:52 AM. Unlike the first disconnect, this second incident was not accompanied by any hydraulic warnings, leaving investigators puzzled about the cause. The lack of correlation between the autopilot disconnects and the hydraulic warnings may indicate a more complex issue at play, possibly involving software or sensor malfunctions that require a detailed examination of the aircraft's systems.

Pilot's Account

In the aftermath of the incident, the pilot underwent a drug screening, which initially returned a “non-negative” result, prompting further testing. The confirmatory test later indicated the presence of cannabis. Reports suggest that the pilot had been asleep for approximately 30 to 35 minutes during the flight, which raises questions about the monitoring of the aircraft during critical phases of the journey. The revelation of the pilot's drug test results has sparked discussions regarding the protocols for pilot fitness and the measures in place to ensure that pilots remain alert and capable during flights.

Witness accounts indicate that the pilot was discussing the air conditioning system with the first officer when the altitude anomaly occurred, resulting in him being thrown to the cockpit floor. The first officer was at the controls while the commander was monitoring the flight. A cabin crew member seated in the observer seat assisted the commander back to his position in the cockpit. This incident highlights the importance of effective communication and teamwork in the cockpit, particularly during unexpected situations where quick decision-making is critical.

The complete sequence of events remains under investigation, as the pilots' accounts could not be independently verified. The incident underscores the importance of rigorous safety protocols and the need for thorough investigations to ensure passenger safety in the aviation industry. The aviation community is closely watching the developments of this case, as it could have implications for pilot training, regulatory oversight, and operational standards across the industry.

Broader Implications

The turbulence incident involving Air India flight AI2379 serves as a stark reminder of the potential dangers associated with air travel. The series of warnings logged during the flight highlights the critical need for ongoing safety assessments and operational checks to prevent similar occurrences in the future. In light of this incident, airlines may need to reevaluate their maintenance and safety protocols to ensure that all systems are functioning optimally before takeoff.

Moreover, the incident raises questions about the broader regulatory framework governing aviation safety. Regulatory bodies worldwide are tasked with ensuring that airlines adhere to strict safety standards, and any lapses in these regulations can lead to catastrophic consequences. This incident may prompt calls for stricter oversight of pilot health and fitness, particularly concerning substance use and fatigue management. The aviation industry has made significant strides in improving safety over the years, but incidents like this remind stakeholders that there is always room for improvement.

Furthermore, the psychological well-being of pilots is becoming an increasingly important topic in aviation safety discussions. The pressures of the job, including long hours and the responsibility of ensuring passenger safety, can take a toll on mental health. Addressing these issues may require a cultural shift within the industry to prioritize mental health alongside physical health, ensuring that pilots are fully equipped to handle the demands of their roles.

As investigations continue, the findings will likely inform future safety regulations and operational standards, not only for Air India but for airlines around the world. The aviation industry must learn from each incident to enhance safety measures and prevent future occurrences. The commitment to safety is paramount, and ongoing vigilance is essential to maintaining the trust of passengers and ensuring the safe operation of flights.

In conclusion, the incident involving Air India flight AI2379 highlights the complexities and challenges associated with aviation safety. The interplay of mechanical issues, human factors, and regulatory oversight underscores the need for a comprehensive approach to safety in the aviation industry. As investigations proceed, the lessons learned from this incident will be vital in shaping the future of air travel, ensuring that safety remains the top priority for all stakeholders involved.
