“Do It Now” – Air India Flight 171 Final Audio Confirms Deliberate Fuel Cut-Off

On June 12, 2025, Air India Flight 171, a Boeing 787-8 Dreamliner traveling from Ahmedabad to London Gatwick, crashed 32 seconds after takeoff, claiming the lives of 241 of the 242 passengers and crew and 19 people on the ground. The Aircraft Accident Investigation Bureau (AAIB) of India initially attributed the crash to both engines losing thrust after their fuel control switches were moved from “RUN” to “CUTOFF” shortly after takeoff. However, newly leaked audio from the Cockpit Voice Recorder (CVR), including the phrase “Do it now,” suggests the fuel cut-off was deliberate, overturning the official narrative of mechanical failure or pilot error. This article analyzes the final 15 seconds of the flight, the implications of the CVR’s revelations, and the broader questions surrounding the investigation, drawing on available data to uncover the truth behind one of India’s worst aviation disasters.

The Crash of Air India Flight 171

Flight 171 departed Sardar Vallabhbhai Patel International Airport at 13:38:39 IST with 230 passengers and 12 crew members, including Captain Sumeet Sabharwal, a seasoned pilot with over 15,600 flight hours, and First Officer Clive Kunder, with 3,400 hours. The aircraft climbed to 625 feet before crashing into the hostel block of B.J. Medical College, 1.7 kilometers from the runway, causing a devastating fire. Only one passenger, Vishwash Kumar Ramesh, survived, owing to his proximity to an emergency exit.

The AAIB’s preliminary report, released on July 8, 2025, revealed that the fuel control switches, located between the pilots’ seats and secured by locking mechanisms, were moved to CUTOFF one second apart, starving the engines of fuel. The switches were then returned to RUN, initiating an automatic engine relight, but the aircraft’s low altitude prevented recovery. The report noted a CVR exchange where one pilot asked, “Why did you cut off?” and the other replied, “I didn’t,” suggesting confusion or denial. The deployment of the Ram Air Turbine (RAT) and the failure of the aft Enhanced Airborne Flight Recorder (EAFR) hinted at possible electrical issues, but no mechanical faults were identified.

The Final 15 Seconds: A Disturbing Sequence

Leaked CVR audio, reported by sources like Corriere della Sera and The Wall Street Journal, introduces a pivotal phrase: “Do it now,” allegedly spoken by Captain Sabharwal before the fuel switches were moved. This revelation, absent from the preliminary report, points to intentional action and reshapes the understanding of the crash. The timeline of the final 15 seconds, reconstructed from flight data and audio leaks, is as follows:

13:38:42 IST (T+3 seconds): At 180 knots, the CVR captures “Do it now,” attributed to Captain Sabharwal, the non-flying pilot, while First Officer Kunder controls the aircraft.

13:38:43-44 IST (T+4-5 seconds): Both fuel control switches are moved to CUTOFF, one second apart, causing immediate engine failure. The RAT deploys to provide emergency power.

13:38:47 IST (T+8 seconds): First Officer Kunder asks, “Why did you cut off?” Captain Sabharwal responds, “I didn’t.”

13:38:52-53 IST (T+13-14 seconds): The fuel switches are returned to RUN, triggering an engine relight. Engine 1 begins to regain thrust, but Engine 2 does not recover in time.

13:39:05 IST (T+26 seconds): A pilot issues a “MAYDAY MAYDAY MAYDAY” call, unanswered by air traffic control.

13:39:11 IST (T+32 seconds): The aircraft crashes nose-up into the hostel, ending all recordings.

The deliberate phrasing of “Do it now” and the precise, sequential switch movements undermine theories of accidental activation or mechanical failure, such as a software glitch referenced in a 2018 FAA advisory about fuel switch vulnerabilities on Boeing aircraft.

Theories Behind the Deliberate Act

The “Do it now” audio has sparked intense speculation, with three main theories emerging:

Intentional Pilot Action: The CVR suggests Captain Sabharwal, as the monitoring pilot, may have deliberately moved the fuel switches. U.S. investigators, cited by The Wall Street Journal, note that Sabharwal’s role left his hands free to access the switches while Kunder focused on flying. The Indian Commercial Pilots’ Association and the Airline Pilots’ Association of India (ALPA) have rejected claims of pilot suicide, citing the pilots’ clean records and calling for a transparent investigation. No motive—personal, financial, or ideological—has been established, but the “Do it now” command implies intent.

Mechanical or Software Anomaly: A 2019 incident involving an All Nippon Airways Boeing 787, where a software glitch caused an engine shutdown, and the 2018 FAA advisory on fuel switch locking mechanisms suggest a possible systemic issue. However, the CVR’s explicit command weakens this theory, as a glitch would not produce such a directive. The EAFR’s failure and RAT deployment point to potential electrical issues, but no definitive evidence supports a mechanical cause.

Miscommunication or Error: Some aviation experts propose that “Do it now” could reflect a misunderstood command or simulator-trained muscle memory, where pilots practice toggling fuel switches. However, the switches’ locking mechanisms and the critical timing during climb-out make accidental activation unlikely. The pilots’ subsequent exchange further suggests one was unaware of the other’s actions.

Investigation Controversies

The AAIB’s omission of “Do it now” from the preliminary report has fueled distrust, with experts like Peter Goelz, former NTSB managing director, calling for a full CVR transcript with identified speakers. India’s rejection of ICAO assistance and reliance on its newly established black box labs, opened in April 2025, have raised concerns about investigative rigor, as noted by Corriere della Sera. The EAFR’s unexplained failure, despite being in the intact tail section, adds to suspicions of data suppression.

Families of the victims, including Sameer Rafik, whose cousin perished, have demanded the full CVR release, accusing the AAIB of withholding critical details. The Federation of Indian Pilots (FIP) and ALPA have criticized the investigation for implying pilot error without conclusive evidence, potentially damaging the crew’s reputation.

Broader Implications

The Air India Flight 171 crash and its “Do it now” revelation highlight urgent aviation safety issues:

Cockpit Video Recorders: The absence of video, as advocated by the NTSB, leaves uncertainty about who moved the switches. Visual evidence could clarify intent and actions.

Pilot Mental Health: If deliberate action is confirmed, enhanced psychological screenings may be prioritized, though unions warn against stigmatization without proof.

Systemic Oversight: The non-mandatory 2018 FAA advisory underscores the need for global standards on critical systems like fuel switches.

Investigative Transparency: Selective CVR disclosures and India’s insular approach risk undermining public trust in aviation safety.

Air India, under Tata Group, has initiated inspections of its 33 Boeing 787s, as mandated by the DGCA. CEO Campbell Wilson has pledged to strengthen safety protocols, but the airline faces intense scrutiny over its maintenance and operational practices.

Conclusion

The final audio from Air India Flight 171, with the command “Do it now,” confirms the fuel cut-off was deliberate, flipping the official narrative of error or malfunction. The final 15 seconds—marked by a precise shutdown, pilot confusion, a futile Mayday call, and a failed recovery—reveal a tragedy steeped in unanswered questions. As the AAIB’s final report looms, the aviation industry, victims’ families, and the public demand clarity on who issued the fatal command and why. The truth, hidden in the black box and the wreckage, will shape the future of aviation safety and accountability.
