# The crash of Air India Flight 171 was deliberate, or its true cause is being covered up **No verdict.** The crash is real and its cause is not yet established: the official investigation is ongoing, with a draft final report due around October 2026. The preliminary report documented that both engine fuel-control switches moved to CUTOFF seconds after takeoff and recorded a brief cockpit exchange about the cutoff, but it did not determine why the switches moved and named no cause. The theories rated here, that the crash was deliberately caused or that the real explanation is being concealed, are unproven; allegations that a specific pilot deliberately downed the aircraft are unproven claims against deceased individuals, not findings, and India's pilots' associations have publicly rejected them. Category: Unsolved Crimes & Disappearances · Era: 2020s · First circulated: June 2025 · Believed by: Suspicion that the public is not being told the full story is widespread, sharpened among victims' families by the confidential cockpit voice recorder and the delayed final report. What is rated here is not the fact of the crash, which is undisputed, but the deliberate-cause and cover-up claims, which remain unproven while the investigation continues. URL: https://theconspiratory.com/theory/air-india-171-crash-theories ## Summary On 12 June 2025, Air India Flight 171, a Boeing 787-8 Dreamliner bound from Ahmedabad to London Gatwick, crashed about half a minute after takeoff into a medical college hostel, killing 260 people: 241 of the 242 aboard and 19 on the ground. One passenger survived. India's Aircraft Accident Investigation Bureau (AAIB) released a preliminary report in July 2025 documenting that both engine fuel-control switches moved to the CUTOFF position seconds after liftoff, and recording a brief cockpit exchange in which one pilot asked why the fuel had been cut off and the other said he had not done so. The report did not establish why the switches moved and reached no conclusion on cause. Into that gap, and hardened when the AAIB told India's Supreme Court in July 2026 that the draft final report would not be ready until around October 2026 and that the full CVR transcript would stay confidential, poured theories that the crash was deliberate or that its true cause is being hidden. This file separates what the investigation has documented from what it has not, and treats every claim that a named, deceased pilot deliberately crashed the aircraft strictly as an unproven allegation, never as fact. ## The claim That the crash of Air India Flight 171 was not an unexplained accident still under investigation, but was deliberately caused, and that authorities know the true explanation and are concealing it, pointing variously to the confidential cockpit voice recorder, the delayed final report, and the ambiguous fuel-switch detail in the preliminary report. ## Origin and timeline - 2025-06-12: Air India Flight 171, a Boeing 787-8 Dreamliner registered VT-ANB, takes off from Ahmedabad at about 13:39 local time bound for London Gatwick with 242 people aboard. Roughly half a minute later it crashes into the hostel of B. J. Medical College, about 1.7 kilometres from the runway. - 2025-06-12: The crash kills 260 people: 241 of the 242 on board and 19 on the ground. A single passenger, seated by an emergency exit, survives. It is the first fatal accident and hull loss of a Boeing 787 since the type entered service. - 2025-06: Both flight recorders are recovered and the AAIB leads the investigation under international accident-investigation rules, with participation from Boeing, GE, the US NTSB and the UK AAIB. Speculation about the cause circulates worldwide within days. - 2025-07-12: The AAIB releases its preliminary report. It documents that the two engine fuel-control switches moved from RUN to CUTOFF about a second apart, seconds after liftoff, and that both engines lost thrust. It records a cockpit exchange in which one pilot asks why the fuel was cut off and the other replies that he did not do so. The report does not identify which pilot spoke, does not establish why the switches moved, and reaches no conclusion on cause. - 2025-07-14: Indian regulators order airlines to inspect the fuel-switch locking mechanism on Boeing aircraft, referencing a 2018 US FAA advisory that had flagged the switch-lock feature. The advisory was not mandatory, and the question of whether the switches moved by hand, by fault, or by some other path remains open. - 2025-07: Indian pilots' bodies, including the Indian Commercial Pilots' Association, the Airline Pilots' Association of India and the Federation of Indian Pilots, publicly reject what they call a reckless insinuation of pilot suicide, criticise the secrecy around the probe, and press for full simulator recreation before any conclusion. International outlets nonetheless name a pilot in speculation the report does not support. - 2026-06-12: On the first anniversary, the final report is still pending and the cause remains formally undetermined. Coverage notes that a year on, investigators have documented what the engines did but not established why. - 2026-07: The AAIB tells the Supreme Court of India that the draft final report is expected around October 2026 and that the CVR transcript will remain confidential under the applicable accident-investigation rules. The court declines to order the transcript's release, reviving cover-up and deliberate-cause theories. ## The evidence, claim by claim - Claim: The fuel-control switches moving to CUTOFF and the cockpit exchange about the cutoff prove that a pilot deliberately shut down the engines. Evidence: This is the claim the record does not support. The preliminary report documents that the switches moved to CUTOFF and that one pilot asked why the fuel was cut off while the other said he had not done it, but it does not identify who spoke, does not say why the switches moved, and reaches no conclusion on cause. Investigators have not ruled out mechanical, electrical or system explanations, a 2018 FAA advisory had flagged the switch-lock feature on Boeing jets, and the possibility of an inadvertent or fault-driven movement remains open. A recorded cutoff and a recorded question about it are documented facts; they are not a finding of intent, and treating them as one convicts deceased people the investigation has not blamed. India's pilots' associations have rejected the suicide theory outright, and this file reports allegations against either pilot strictly as unproven claims. - Claim: Keeping the cockpit voice recorder transcript confidential proves the authorities are hiding the truth. Evidence: CVR confidentiality is the international norm, not an anomaly. Accident-investigation frameworks, including ICAO Annex 13 and India's own Aircraft (Investigation of Accidents and Incidents) Rules, restrict release of cockpit recordings to protect the safety investigation and the privacy of the crew, and the Supreme Court declined to order the transcript's release under that framework rather than to bury it. Withholding a raw transcript while the probe is open is standard practice on major crashes worldwide. It is consistent with a cover-up and equally consistent with a routine, rules-bound investigation, so on its own it proves neither. - Claim: The final report being pushed to around October 2026 shows the cause has been found and is being suppressed. Evidence: A delayed final report is the ordinary tempo of a complex crash inquiry, not evidence of concealment. The preliminary report appeared within a month, as the rules envisage; final reports on major accidents commonly take well over a year while wreckage, recorder data, engine components and manufacturer systems are analysed. Notably, the loudest push for more work has come from the pilots' side, which has demanded full simulator recreation of the sequence before any conclusion is drawn. A timeline that critics say is too slow to satisfy them is hard to reconcile with a finished answer being hidden. - Claim: The preliminary report was selectively written to steer blame onto the pilots while omitting warnings and system data. Evidence: This is a real critique of process, and it is not the same as proof of a deliberate crash. The Federation of Indian Pilots and other bodies argued that relevant cockpit warning and system data appeared to be missing from the interim document and called for detailed simulation before conclusions. The AAIB has stressed that the preliminary report is interim and that findings will come in the final report. That an interim document is incomplete, and contested by pilots, is an argument for waiting on the full investigation, not a demonstration that the crash was intentional or that a specific cause is being covered up. - Claim: The crash was sabotage, a bomb, or an external attack that is being kept from the public. Evidence: No investigating authority has reported any evidence of sabotage, an explosive device or external interference, and the documented sequence centres on the loss of engine thrust after the fuel-control switches moved to CUTOFF. The single confirmed survivor and numerous witnesses described an ordinary takeoff followed by a rapid loss of lift, not an in-flight explosion. Absent any such finding, the sabotage theory rests on the general secrecy of the process rather than on anything in the record. ## Why people believe it - The core facts are genuinely shocking and true: a modern wide-body crashed within about half a minute of takeoff, into a building full of people, killing 260. When a catastrophe is this stark, a still-open investigation can feel like an evasion rather than an honest lack of answers. - The fuel-switch detail is ambiguous in a way that invites the darkest reading. A recorded movement of both switches to CUTOFF and a recorded question about who cut the fuel are documented, but their cause is not, and a public straining for an explanation tends to fill that gap with intent rather than with an unresolved fault. - The confidential CVR transcript and the delayed final report read, to grieving families and a suspicious public, like withholding. Confidentiality that is routine to investigators looks like secrecy to people who have been given no cause and no closure. - Early information was contested and, critics said, incomplete, and Indian pilots' bodies openly accused commentators of a rush to blame the crew. Once one set of experts says the story is being told unfairly, distrust of the whole account spreads. - A deliberate act or a cover-up supplies what an unexplained accident withholds: an agent, a motive and a resolution. A fault no one has yet pinned down offers grief without an answer, and a plot at least offers a shape and someone to hold responsible. ## Open questions - Why did the fuel-control switches move to CUTOFF seconds after takeoff? The preliminary report documented the movement but not its cause, and whether it was a hand action, a mechanical or electrical fault, a system behaviour, or something else has not been publicly established. - What does the full cockpit voice recorder contain, and who said what? The report quoted a brief exchange without identifying the speakers, and the complete transcript is being kept confidential, leaving the fuller context unresolved outside the investigation. - What will the final report conclude, and will it satisfy the pilots' bodies that demanded full simulator recreation of the sequence? Until the draft final report expected around October 2026, the official cause remains formally undetermined. - Did the 2018 FAA advisory about the fuel-switch locking feature, or the inspections later ordered, have any bearing on this aircraft? Whether a hardware factor contributed has not been publicly resolved. ## Latest developments - 2026-07-15T00:00Z: The AAIB told the Supreme Court of India that the draft final report into the crash is expected around October 2026 and that the cockpit voice recorder transcript will remain confidential under the applicable accident-investigation rules. The court declined to order the transcript's release. The cause remains formally undetermined, and cover-up and deliberate-cause theories resurged in response.
