Scientists Finally Solved The Air India 171 Crash Mystery, And It’s Not What You Think

On June 12, 2025, Air India Flight AI171, a Boeing 787-8 Dreamliner, took off from Ahmedabad’s Sardar Vallabhbhai Patel International Airport en route to London Gatwick. Just 32 seconds later, at 1:39 pm local time, the aircraft plummeted into a densely populated area, crashing into the Byramjee Jeejeebhoy Medical College and Civil Hospital. The disaster claimed 241 lives on board, 19 on the ground, and left only one survivor, Vishwash Kumar Ramesh. For months, the mystery of what caused this catastrophic crash baffled investigators, aviation experts, and the public. Initial theories ranged from mechanical failure to pilot error, but recent findings have revealed a truth far more complex and unsettling than anyone anticipated. This article delves into the latest revelations, piecing together the evidence to uncover what really brought down Flight AI171.

The Tragic Timeline

Flight AI171, piloted by Captain Sumeet Sabharwal and First Officer Clive Kunder, was a routine international flight carrying 229 passengers and 12 crew members. The weather was clear, with no storms or turbulence reported. The aircraft, a state-of-the-art Boeing 787 Dreamliner, was equipped with GE engines and had no prior maintenance issues. Yet, within seconds of takeoff, the pilots issued a desperate Mayday call as the plane reached a mere 625 feet before losing altitude and crashing into a doctors’ accommodation and student canteen. The explosion was catastrophic, scattering debris and leaving investigators with a daunting task: to determine what caused such a sudden and violent failure.

Early Theories and Speculation

In the immediate aftermath, speculation ran rampant. Some pointed to potential mechanical failures, such as dual engine failure or a fuel system malfunction. Others questioned whether bird strikes could have incapacitated both engines, though no evidence of bird activity was found at the crash site. The possibility of pilot error also surfaced, fueled by the plane’s rapid descent and the pilots’ final transmission reporting “no thrust” and “losing power.” Social media platforms, including posts on X, reflected public sentiment, with some users suggesting a system malfunction rather than human error, while others called for a deeper investigation into Boeing’s design.

The Aircraft Accident Investigation Bureau (AAIB), supported by the U.S. National Transportation Safety Board (NTSB) and Boeing, launched a multi-agency probe. Both black boxes—the flight data recorder (FDR) and cockpit voice recorder (CVR)—were recovered, despite fire damage, and became critical to unraveling the mystery. Early clues pointed to the aircraft’s Ram Air Turbine (RAT), an emergency power system, deploying just before the crash, suggesting a significant electrical or hydraulic failure.

The Breakthrough: The 10-Second Mystery

In July 2025, the AAIB released a preliminary report that shifted the focus to a critical 10-second window in the cockpit. According to the report, both engine fuel control switches were moved from the “RUN” to “CUTOFF” position within one second of each other, approximately 42 seconds after takeoff. This action starved the engines of fuel, causing an immediate loss of thrust. The CVR captured a perplexing exchange: one pilot asked, “Why did you cut off?” to which the other replied, “I did not do so.” The switches were reset to “RUN” after a 10-second delay, but the aircraft was too low and slow to recover. At impact, one engine was regaining thrust, but it was too late.

This revelation sparked intense debate. The fuel cutoff switches, equipped with spring-loaded locking mechanisms, require deliberate action to move, making accidental activation unlikely. The CVR’s indication of confusion between the pilots—Captain Sabharwal with 15,638 hours of experience and First Officer Kunder with 3,403 hours—raised questions about human factors, such as miscommunication or sensory overload. However, the report explicitly stated that no conclusions had been drawn, ruling out mechanical failure, maintenance issues, or fuel quality problems.

A New Perspective: Systemic and Human Factors

As investigators dug deeper, a more nuanced picture emerged. Aviation experts, including Peter Goelz, a former NTSB managing director, emphasized the need for voice identification to clarify the CVR exchange. The pilots’ confusion suggested a possible “startle effect,” a psychological response to sudden alarms that can momentarily impair decision-making. The deployment of the RAT, observed in video footage showing a “protrusion on the belly of the aircraft,” indicated a massive electrical or hydraulic failure, possibly triggering the fuel cutoff as a secondary effect.

Some experts hypothesized an uncommanded shutdown, where the engines stopped without deliberate pilot action, potentially due to an electronic or mechanical glitch not yet identified. A 2019 FAA bulletin noted issues with Boeing 737 fuel control switches disengaging unintentionally, though Air India’s subsequent inspections of its 787 fleet found no such faults. This raised the possibility that the fuel cutoff was a response to an underlying system failure rather than the primary cause.

Sandeep Choudhary, President of the India Chapter of Save Earth Mission, claimed to have “decoded” the crash in just three minutes by analyzing key data points. At the Global Vision Unveiling event on July 3, 2025, he promised to reveal a truth that went beyond the official narrative, though his findings remain unverified and have been met with skepticism by aviation authorities. His announcement, trending under #SandeepDecodedAI171, fueled public speculation about a possible cover-up.

The Survivor’s Account

Vishwash Kumar Ramesh, the sole survivor, provided a chilling perspective. From his hospital bed, he recounted that “within five to ten seconds [after takeoff], it felt like [the plane] was stuck in the air. Suddenly, the lights started flickering green and white. The aircraft wasn’t gaining altitude and was just gliding before it suddenly slammed into a building and exploded.” His account of flickering lights aligned with expert analysis suggesting the aircraft’s generators were malfunctioning, possibly switching to backup systems.

Ramesh’s escape was miraculous. He forced his way past a broken emergency door and walked away from the wreckage, assisted by locals. His testimony has been pivotal, supporting the theory of an electrical system failure linked to engine malfunction. Aviation specialist David Learmount noted that such flickering lights could indicate a power system switching to backups, a symptom of deeper issues.

Implications for Aviation Safety

The Air India Flight AI171 crash has prompted significant action. The Directorate General of Civil Aviation (DGCA) ordered enhanced inspections of Air India’s Boeing 787 fleet, focusing on fuel monitoring systems, electronic engine controls, and hydraulic systems. Simulator tests are ongoing to recreate the flight’s configuration, and experts are advocating for cockpit video recorders to provide visual evidence of pilot actions.

The tragedy has also reignited debates about pilot training for emergency scenarios. The 10-second delay in resetting the fuel switches, combined with the “startle effect,” suggests that even experienced pilots can struggle under extreme pressure. The Indian Commercial Pilots’ Association has pushed back against premature blame, arguing that systemic issues, such as potential flaws in the Boeing 787’s fuel control system, must be thoroughly investigated.

A Mystery Not Fully Solved

While significant progress has been made, the Air India Flight AI171 crash remains an enigma. The preliminary report rules out mechanical failure but highlights human factors and potential systemic issues. The truth likely lies in a complex interplay of electrical or hydraulic failure, uncommanded engine shutdown, and cockpit confusion. The ongoing investigation, expected to conclude within a year, will rely on further analysis of the black boxes, wreckage, and simulator data.

What is clear is that the crash was not the result of a single, obvious cause like pilot error or a bird strike. Instead, it appears to stem from a rare and catastrophic chain of events that overwhelmed the crew and aircraft systems. The findings could have far-reaching implications for the aviation industry, potentially leading to design changes in the Boeing 787 and revised training protocols.

Conclusion

The Air India Flight AI171 disaster is a stark reminder of the fragility of air travel, even with advanced technology and experienced crews. The latest revelations—centered on the 10-second cockpit mystery, the survivor’s account, and the RAT deployment—point to a truth far more intricate than initial theories suggested. As the world awaits the final report, the focus remains on ensuring such a tragedy never happens again. For now, the story of Flight AI171 serves as both a puzzle and a call to action for safer skies.
