Why Air India Flight 171 Could Not Send a Full Emergency Signal: Unraveling a Tragic Mystery

On June 12, 2025, Air India Flight 171, a Boeing 787-8 Dreamliner bound for London Gatwick from Ahmedabad, India, crashed just 32 seconds after takeoff, claiming the lives of 241 of the 242 passengers and crew, along with 19 people on the ground. The sole survivor, Vishwash Kumar Ramesh, escaped through a shattered emergency exit, but the catastrophe left a haunting question: why could the pilots only transmit a brief mayday call without a full emergency signal? The preliminary report by India’s Aircraft Accident Investigation Bureau (AAIB), released on July 8, 2025, points to a catastrophic sequence involving the aircraft’s fuel control switches, but gaps in the communication timeline deepen the mystery. This article explores the crash’s details, the failed emergency signal, the ongoing investigation, the human toll, and the broader implications for aviation safety in an era of heightened scrutiny.

The Crash: A 32-Second Tragedy

Air India Flight 171 took off from Ahmedabad’s Sardar Vallabhbhai Patel International Airport at 13:38:39 IST, carrying 230 passengers and 12 crew members. Piloted by Captain Sumeet Sabharwal, a veteran with 15,638 flight hours, and First Officer Clive Kunder, with 3,403 hours, the flight was cleared for a full-length takeoff on runway 23 under clear weather conditions—light winds at 6 knots and visibility of 6 kilometers. The aircraft reached a maximum altitude of 625 feet before disaster struck. According to the AAIB report, three seconds after liftoff, both fuel control switches transitioned from “RUN” to “CUTOFF,” starving the engines of fuel and causing a total loss of thrust. The ram air turbine (RAT), an emergency power source, deployed automatically five seconds later, but the plane began a rapid descent, crashing into the B.J. Medical College hostel 1.7 kilometers from the runway at 13:39:11 IST.

The mayday call, issued nine seconds before impact, was chillingly brief: “MAYDAY MAYDAY MAYDAY… no thrust, losing power, unable to lift.” Air traffic control (ATC) requested the flight’s call sign for identification, but no response followed. The cockpit voice recorder (CVR) and flight data recorder (FDR) ended six seconds later, leaving investigators with incomplete data on why the full emergency signal—a standard protocol detailing the nature of the crisis—was never transmitted. The crash, the first fatal accident involving a Boeing 787 since its 2011 debut, killed all but one onboard and 19 on the ground, making it India’s deadliest aviation disaster since 1996.

The Failed Emergency Signal: A Puzzle in the Cockpit

The inability to send a full emergency signal is central to the mystery. In aviation, a mayday call typically includes the flight’s call sign, position, nature of the emergency, and intentions, allowing ATC to coordinate a response. The AAIB report reveals that the pilots’ communication was cut short, with only a partial distress call transmitted. Several factors likely contributed, rooted in the rapid sequence of events:

Fuel Control Switch Anomaly: The AAIB found that both fuel control switches moved to “CUTOFF” within one second of each other, an action typically performed only after landing or in emergencies like an engine fire. The cockpit voice recording captures one pilot asking, “Why did he cut off?” with the other responding, “I did not,” though it’s unclear who spoke. The switches, equipped with spring-loaded locking mechanisms to prevent accidental movement, returned to “RUN” 10 and 14 seconds later, triggering automatic engine relight attempts. One engine partially regained thrust, but the other failed to recover. This 14-second window of chaos likely consumed the pilots’ attention, leaving little time for a detailed signal.

Time Constraints and Workload: The crash occurred 32 seconds after takeoff, with the mayday call at 23 seconds. This left the pilots with less than 10 seconds to assess the dual engine failure, deploy the RAT, attempt engine restarts, and communicate with ATC. Aviation expert Amit Singh, quoted in The Hindu, noted: “In such a rapid cascade, prioritizing aircraft control over communication is instinctive.” The CVR suggests the pilots were troubleshooting the switches, with one possibly manipulating controls while the other issued the call, fragmenting their focus.

System Limitations: The RAT, which deployed to provide emergency hydraulic and electrical power, supports only critical systems like flight controls, not full communication arrays. While the Boeing 787’s advanced systems should maintain radio functionality, a complete power loss may have degraded signal clarity or range, as speculated in a Reddit thread on r/aviation. The AAIB report confirms the FDR and CVR stopped six seconds after the mayday, suggesting a total electrical failure as the plane hit the ground, severing further communication.

The brief call—“no thrust, losing power”—conveyed the core issue but lacked specifics, hindering ATC’s immediate response. The controller’s request for the call sign, unanswered, reflects the chaos in the cockpit, as BBC News reported. The mystery deepens with the switches’ movement: Was it human error, a mechanical fault, or an external factor? The AAIB’s preliminary findings rule out bird strikes, fuel contamination, or adverse weather, narrowing the focus to the cockpit or aircraft systems.

The Investigation: Searching for Answers

India’s AAIB, joined by the U.S. National Transportation Safety Board (NTSB) and the UK’s Air Accidents Investigation Branch, is probing the crash. The recovered black boxes—enhanced airborne flight recorders combining CVR and FDR—provide critical data, though heat damage from the post-crash fire posed challenges. The AAIB report, released July 8, 2025, notes the fuel switches’ transition to “CUTOFF” at 13:38:42 IST, with the RAT deploying at 13:38:47. The first switch returned to “RUN” at 13:38:52, the second at 13:38:56, and the mayday call followed at 13:39:05. The crash occurred six seconds later, leaving a 23-second window from switch movement to impact.

Investigators are focusing on several leads:

Human Error: The CVR’s exchange suggests one pilot may have inadvertently moved the switches, though their locking mechanisms make this unlikely. A 2018 FAA advisory, cited by The Guardian, noted some Boeing 737 fuel switches had disengaged locks, a design also used in the 787-8. Air India’s failure to inspect these, as it was advisory, not mandatory, is under scrutiny.

Mechanical or Software Glitch: The switches’ near-simultaneous movement raises questions about a potential system fault. Al Jazeera reported speculation about a software issue, though the AAIB found no evidence of this. The full authority digital engine control (FADEC) attempted automatic restarts, but the rapid descent limited recovery time.

Pilot Dynamics: Sabharwal, monitoring, and Kunder, flying, were both experienced and rested, passing pre-flight breathalyzer tests. The CVR’s ambiguity—who said what—complicates assigning blame, with The Wall Street Journal suggesting Sabharwal may have moved the switches, though unnamed U.S. pilots argued Kunder’s focus on flying made this unlikely.

The investigation, expected to conclude with a final report by June 2026 per ICAO rules, faces pressure to clarify these gaps. The Indian Commercial Pilots Association, quoted in Al Jazeera, decried speculation about pilot suicide as “reckless,” urging patience for verified findings.

The Human Toll and Survivor’s Tale

The crash’s devastation was profound. The Boeing 787 smashed into a medical college hostel, killing 19 on the ground and injuring 67, with the aircraft destroyed in a fiery explosion. Vishwash Kumar Ramesh, a 40-year-old British citizen seated by an emergency exit, survived when his section detached, as reported by Wikipedia. Treated for minor injuries, Ramesh attended his brother’s funeral a day later, a poignant reminder of the personal tragedies within the larger disaster.

The response was swift: over 300 firefighters, 60 vehicles, and 20 ambulances deployed, with roads closed to aid rescue efforts. The Central Industrial Security Force and Indian Army assisted, while Ahmedabad’s airport suspended operations briefly. The sole survivor’s story, alongside the loss of figures like former Gujarat Chief Minister Vijay Rupani, underscored the crash’s far-reaching impact.

Cultural and Industry Implications

The Air India 171 crash, India’s worst since 1996, has reignited debates about aviation safety. The Boeing 787’s flawless record until this incident, as noted by The Air Current, raises questions about design vulnerabilities, particularly the fuel switch locks. The FAA’s 2018 advisory, not enforced on Air India’s fleet, has prompted calls for mandatory inspections, with India’s DGCA ordering one-time checks on all Boeing 787s post-crash. Social media, with X posts like @VishnuNDTV demanding the full CVR transcript, reflects public frustration with incomplete answers.

The incident parallels 2025’s trend of high-profile tragedies, like Ozzy Osbourne’s death, where public mourning meets scrutiny of human error. The brief mayday call, hauntingly incomplete, fuels speculation akin to viral scandals, with Reddit threads debating pilot intent versus system failure. The crash’s aftermath, including 150 ambulances and municipal support, mirrors society’s collective response to loss, blending urgency with grief.

Looking Ahead: Lessons and Accountability

The AAIB’s final report will shape aviation protocols, potentially mandating switch redesigns or stricter maintenance checks. For Air India, the tragedy—its first fatal crash since 1985—demands transparency to rebuild trust. The mystery of the failed signal, tied to the rapid 32-second descent, underscores the need for enhanced pilot training and system redundancies. As families mourn and Ramesh rebuilds, the crash remains a stark reminder: in aviation, seconds can mean everything.

In conclusion, Air India Flight 171’s incomplete emergency signal is a haunting puzzle within a devastating tragedy. The fuel switch anomaly, cockpit chaos, and fleeting mayday call reveal the fragility of even advanced aircraft. As investigators probe and the world mourns, the quest for answers drives a deeper reckoning, ensuring the 260 lives lost are honored through safer skies.
