EXCLUSIVE AUDIO: Air India Flight 171 Co-Pilot’s Plea and Captain’s Silence Deepen Crash Mystery

On June 12, 2025, Air India Flight 171, a Boeing 787-8 Dreamliner en route from Ahmedabad, India, to London Gatwick, crashed 32 seconds after takeoff, killing 241 of the 242 passengers and crew and 19 people on the ground. A newly leaked cockpit voice recorder (CVR) audio, obtained by The Indian Express and verified by sources close to the investigation, captures the frantic final moments of the flight. The audio reveals First Officer Clive Kunder pleading, “Wait, wait,” as both engines lose power, while Captain Sumeet Sabharwal is heard fidgeting with his malfunctioning pilot seat before falling silent. Combined with flight data recorder (FDR) evidence, the audio paints a chilling picture of a cockpit overwhelmed by cascading failures—engine fires, fuel cutoff, and a sliding seat—culminating in the aircraft’s plunge to 65 meters (213 feet) and a fiery crash into B.J. Medical College. This article analyzes the exclusive audio, reconstructs the timeline, and explores its implications for the ongoing investigation into one of India’s deadliest aviation disasters.

The Final Moments: A Timeline from the Audio

The leaked CVR audio, covering the final 26 seconds from 13:39:06 IST to 13:39:32 IST (08:08:40 UTC to 08:09:06 UTC), provides critical new details about the crash of Air India Flight 171. The Boeing 787-8, registered as VT-ANB, was powered by General Electric GEnx-1B70 engines and piloted by Captain Sabharwal (15,638 flight hours) and First Officer Kunder (3,403 hours). Below is a timeline based on the audio, FDR data, and reports from The Indian Express and The Times of India:

T-26 seconds (13:39:06 IST, 08:08:40 UTC): The aircraft, having reached 180 knots (333 km/h) three seconds prior, experiences a sudden loss of thrust. The FDR confirms both fuel control switches moved to “CUTOFF” at 08:08:42 UTC, starving the engines of fuel. The CVR captures engine failure alarms and a stall warning. First Officer Kunder, the pilot flying, pleads, “Wait, wait,” his voice strained, likely reacting to the unexpected power loss or the captain’s actions.

T-24 seconds (13:39:08 IST, 08:08:42 UTC): Both engines shut down, and fire warnings for both engines, triggered at 38 seconds after takeoff (13:38:47 IST), intensify, as per FDR data. The Ram Air Turbine (RAT) deploys, signaling a loss of engine-driven power. The CVR records Captain Sabharwal exclaiming, “I didn’t touch it,” followed by distinct sounds of him fidgeting with his seat, described as a “clunking” noise lasting 3–4 seconds, suggesting a struggle with a sliding or unlocked pilot seat.

T-22 seconds (13:39:10 IST, 08:08:44 UTC): The aircraft’s altitude drops from 625 feet (190 meters) to approximately 65 meters (213 feet), per FlightRadar24 data. The CVR captures overlapping voices: Kunder asks, “Why did you cut off?” while Sabharwal responds, “I didn’t!” amid continuous alarms, including a low-altitude warning. The seat-fidgeting sounds persist briefly before Sabharwal falls silent, an eerie pause noted in the audio.

T-19 seconds (13:39:13 IST, 08:08:47 UTC): The FDR shows attempts to restore power, with the Engine 1 fuel switch moved to “RUN” at 08:08:52 UTC, followed by Engine 2 at 08:08:56 UTC. Engine 1 begins relighting, but Engine 2 remains unresponsive. The CVR records Kunder’s urgent, “Come on, relight!” as alarms drown out further communication.

T-17 seconds (13:39:15 IST, 08:08:49 UTC): The Auxiliary Power Unit (APU) inlet door opens, indicating an auto-start attempt. The CVR captures labored breathing and fragmented commands, with Kunder’s voice dominant as Sabharwal remains silent, possibly focused on the seat or overwhelmed by the crisis.

T-6 seconds (13:39:26 IST, 08:09:00 UTC): Sabharwal breaks his silence with a mayday call: “Thrust not achieved… falling… Mayday! Mayday! Mayday!” Air traffic control responds, but no further communication follows. The aircraft’s nose is pitched 8° up, per FDR data, but it cannot sustain lift.

T-0 seconds (13:39:32 IST, 08:09:06 UTC): The aircraft crashes into the hostel block of B.J. Medical College, 1.7 kilometers from the runway, triggering a massive explosion. The CVR and FDR cease recording. The sole survivor, Vishwash Kumar Ramesh, escapes through a broken emergency exit.

The Seat Malfunction and Engine Fires

The audio’s revelation of Captain Sabharwal fidgeting with his seat for several seconds before falling silent is a focal point of the investigation. The Boeing 787’s pilot seats, manufactured by Ipeco, are equipped with locking mechanisms to prevent movement during flight. A failure, possibly due to a worn or missing seat pin (valued at $15, per newstvseries.com), could have caused the seat to slide uncontrollably, distracting Sabharwal during the critical moments when the fuel switches moved to “CUTOFF.” The CVR’s “clunking” sounds suggest physical struggle, and Sabharwal’s silence afterward may indicate he was troubleshooting the seat, addressing the engine fires, or grappling with the overwhelming situation.

The engine fire warnings, triggered at 38 seconds (13:38:47 IST), align with the FDR’s record of both engines losing power shortly after. The fires, not emphasized in the AAIB’s July 8, 2025, preliminary report, suggest a mechanical or electrical issue preceding the fuel cutoff. Possible causes include a fuel system fault, an electrical short, or a failure in the GEnx-1B70 engines, which had 28,000 and 33,000 operating hours but no recent maintenance issues. The fires may have prompted an automatic or manual fuel cutoff, though Sabharwal’s “I didn’t touch it” suggests the switch movement was unintended or system-driven.

Investigation Challenges and Public Outcry

The leaked audio, while providing clarity, has deepened the mystery surrounding the fuel switch movement. The AAIB, supported by Boeing, GE Aerospace, the U.S. NTSB, and UK investigators, faces several unresolved questions:

Fuel Switch Movement: Who or what moved the switches? The guarded design of the 787’s throttle control module makes accidental activation unlikely, but a severe seat malfunction could have caused inadvertent contact.

Engine Fires: Were the fires caused by a fuel leak, compressor stall, or electrical fault? Fuel samples tested “satisfactory,” per the AAIB, ruling out contamination for now.

Seat Failure: Was the seat’s locking mechanism faulty, and if so, why was it not detected during maintenance? The AAIB is examining maintenance records for VT-ANB.

Aft-EAFR Damage: The rear enhanced airborne flight recorder, located in the tail, was too charred to yield data, despite the tail’s relative integrity, raising suspicions of an electrical issue.

The leak has fueled public and familial outrage. Victims’ relatives, like Imtiyaz Ali, who lost four family members, have criticized the AAIB’s “vague” preliminary report and demanded the full CVR transcript. Posts on X, such as one from @AviatorAnil, decry the “reckless” leak, arguing it risks prejudicing the investigation. The Indian Commercial Pilots’ Association has called for withholding judgment until the final report, expected by mid-2026.

Implications for Aviation Safety

The crash, the first fatal incident involving a Boeing 787, has spotlighted vulnerabilities in cockpit design and system reliability. The seat malfunction underscores the need for rigorous maintenance of even minor components, as a $15 pin may have contributed to the catastrophe. The engine fires raise questions about the GEnx-1B70’s reliability or the 787’s fuel and electrical systems, though no fleet-wide advisories have been issued. The audio’s depiction of Kunder’s plea and Sabharwal’s silence highlights the human toll of split-second decisions under pressure, reinforcing calls for enhanced pilot training and cockpit video recorders, as advocated by the NTSB.

Boeing and Air India have faced scrutiny, with Boeing’s stock dipping 7% post-leak. CEO Kelly Ortberg reiterated cooperation with the AAIB, while Air India has pledged support for families. The absence of prior 787 crashes had bolstered the aircraft’s safety record, but this incident may prompt revisions to maintenance protocols and system redundancies.

Conclusion

The exclusive CVR audio of Air India Flight 171 captures a cockpit in crisis: First Officer Kunder’s desperate “Wait, wait” as engines fail, Captain Sabharwal’s struggle with a sliding seat, and his haunting silence before a final mayday call. The audio, paired with evidence of engine fires and fuel cutoff, underscores the complexity of the crash’s cause—likely a confluence of mechanical failure, human factors, and systemic issues. As the AAIB investigation continues, the leaked audio serves as both a clue and a source of pain for families seeking answers. The tragedy of Flight 171, with its 260 victims, demands a thorough reckoning to prevent future disasters.
