Quick summary
One year after Air India flight AI171 crashed 32 seconds after takeoff from Ahmedabad on 12 June 2025, killing 260 people — including 52 British nationals and 169 Indian nationals — India’s Aircraft Accident Investigation Bureau has still not published its final report. India’s Civil Aviation Minister stated in early May 2026 that the probe is in its final stage and a report would “mostly” be released within one month. Families of victims, many based in Leicester, UK, say they want truth before compensation.
Preliminary findings identified a dual engine fuel cut-off within about one second of each other immediately after takeoff, with no mechanical defects identified. The final report, when released, could trigger safety directives affecting Boeing 787 operations globally.
Twelve months have passed since a Boeing 787-8 operated by Air India fell out of the sky over Ahmedabad. 260 people died — on the aircraft and on the ground — and their families are still waiting for an official explanation.
Flight AI171, bound for London Gatwick, went down on 12 June 2025, less than a minute after wheels-up. The preliminary report from India’s Aircraft Accident Investigation Bureau (AAIB) confirmed that fuel supply to both engines was cut off within approximately one second of each other shortly after takeoff, causing loss of thrust. What it did not confirm was why.
That question — why — is what families in Leicester and across the UK and India are demanding an answer to. Mohammed Shoeb Iproliya, whose wife Nusratjahan Jethara was among those killed, has said publicly he does not want money. He wants the truth about what happened and who is responsible. His wife had called him that morning to remind him to meet her at Gatwick.
India’s Civil Aviation Minister Ram Mohan Naidu said on 8 May 2026 that the investigation is in its “final stage” and that the AAIB’s final report will “mostly” be released within one month. That window is now open. For the families, it cannot close fast enough.
What the investigation has established — and what remains unresolved
The AAIB’s preliminary report, published on 12 July 2025, laid out the accident sequence in stark terms. Both engine fuel switches moved to the cut-off position within about one second of each other immediately after takeoff. Engines lost thrust. The crew had seconds to respond. The aircraft struck buildings near BJ Medical College in Ahmedabad 32 seconds after takeoff, killing 241 of the 242 people on board and 19 people on the ground.
Preliminary findings have indicated no evidence of mechanical or maintenance defects in the aircraft or its engines, no fuel quality issues, and no problems with pilot medical status. That leaves cockpit actions and human factors as the central focus of the continuing investigation — a conclusion that raises as many questions as it answers, and one that families like Sameer Rafik’s find deeply unsatisfying. Rafik, whose cousin Faizan died on the flight, has publicly questioned whether experienced pilots could have caused this and called for a thorough accounting of fault.
The AAIB formally opened its investigation on 12 June 2025 and recovered the flight data and cockpit voice recorders the following day. India’s government also established a separate high-level committee under the Union Home Secretary for an independent inquiry. The investigation operates under ICAO Annex 13 standards, which require a final report “as soon as possible” and, if delayed beyond 12 months, an annual interim statement. That 12-month threshold has now been crossed.
For the full technical sequence, the UK AAIB’s acknowledgment of the preliminary report confirms British involvement in the investigation given the number of UK nationals on board and the UK-based destination. Separately, ATC’s ongoing coverage of the AI171 investigation delay has tracked how engine analysis work in France and the United States has extended the timeline.
| Factor | Detail | Status / significance |
|---|---|---|
| Total fatalities | 260 (241 on board, 19 on ground) | India’s worst aviation disaster in over a decade; first fatal 787 hull loss |
| Nationalities (on board) | 169 Indian nationals, 52 British nationals | UK AAIB involved in investigation; Montreal Convention applies to UK claims |
| Time from takeoff to impact | 32 seconds | Dual fuel cut-off identified; no mechanical defects found |
| Black boxes recovered | 13 June 2025 (day after crash) | FDR and CVR data central to final report |
| Preliminary report published | 12 July 2025 | Confirmed fuel cut-off sequence; cause not determined |
| Final report status | Expected “mostly” within one month of 8 May 2026 | 12-month ICAO Annex 13 threshold passed; interim statement obligation triggered |

Why the report’s delay matters beyond the grief
The gap between a crash and its final investigation report is not just a bureaucratic timeline. It is the period during which the global aviation safety system operates without the full picture. ICAO Annex 13 investigations exist specifically to generate safety recommendations — findings that regulators like India’s DGCA, the FAA, and EASA can translate into mandatory changes to cockpit procedures, checklists, crew training, or hardware. Until the AI171 final report is published, none of that can happen for whatever systemic issue, if any, this accident reveals.
Compensation is a separate track. Under the Montreal Convention, which applies in both India and the UK, carriers face strict liability for proven damages up to 128,821 Special Drawing Rights per passenger, with no cap if negligence is established. Standard EU261/UK261 delay compensation does not apply here — wrongful-death claims proceed under civil aviation and tort law. Families who have been told to wait for the report before pursuing full claims are, in effect, waiting for the legal foundation of their cases.
The forward signal is clear enough: if the AAIB delivers its report on the ministerial timeline, the safety feedback loop closes relatively quickly and Air India’s India–UK operations continue under whatever new directives follow. If the timeline slips again, expect louder parliamentary scrutiny in both India and the UK, and possible pressure from US authorities given Boeing and GE Aerospace‘s involvement.
Steps for families and travelers affected by AI171
The AAIB final report is imminent but not yet published — and its release will set off a sequence of legal, regulatory, and operational consequences that affected families and India–UK travelers need to be ready for.
- Monitor the AAIB and Ministry of Civil Aviation directly. Official updates on the final report will appear on India’s Press Information Bureau site and the AAIB’s own publications. Do not rely on third-party summaries for legal or compensation purposes — the primary document matters.
- Understand your compensation framework before the report drops. For families of victims, claims proceed under the Montreal Convention, not standard passenger rights rules. Liability is strict up to the SDR threshold; negligence claims above that threshold require legal representation. Engage aviation law specialists in India or the UK now, not after publication.
- UK-based families should note UK AAIB involvement. The UK AAIB has been formally engaged given the number of British nationals on board. Their parallel findings may carry weight in UK civil proceedings independent of the Indian AAIB’s final report.
- Travelers booked on Air India India–UK routes should review DGCA and Air India newsroom advisories after the final report is published for any safety recommendations or operational changes that follow. No operational changes are in effect now.
- If the report is delayed beyond the ministerial timeline, ICAO Annex 13 requires an annual interim statement once the 12-month mark passes — that threshold has now been crossed. Families and advocates can cite this standard in demanding accountability.
Watch: The AAIB final report release, expected around mid-2026. If published on schedule, it will determine whether safety directives are issued for 787 operations globally and provide the evidentiary foundation for negligence claims above the Montreal Convention’s strict-liability threshold.
Questions? Answers.
What did the preliminary report say caused the AI171 crash?
India’s AAIB preliminary report, published on 12 July 2025, confirmed that fuel supply to both engines was cut off within approximately one second of each other shortly after takeoff, causing loss of thrust. The report identified no mechanical defects, no fuel quality issues, and no problems with pilot medical status. The final cause has not been determined; human factors and cockpit actions remain the central focus of the continuing investigation.
Are families of AI171 victims entitled to compensation, and when can they claim it?
Yes. Under the Montreal Convention, which applies in both India and the UK, Air India faces strict liability for proven damages up to 128,821 Special Drawing Rights per passenger. If negligence is established, there is no upper cap. Standard EU261 or UK261 delay compensation does not apply to accidents of this nature. Full negligence claims typically require the final investigation report as evidentiary support, which is why families have been advised to await its publication before pursuing the highest-value claims.
Does the AI171 crash affect the safety of current Air India flights to the UK?
No operational changes are currently in effect as a result of the AI171 investigation. The AAIB has not yet issued safety recommendations, and no airworthiness directives specific to AI171 have been mandated by the DGCA, FAA, or EASA. Once the final report is published, regulators may issue directives if systemic issues are identified. Until then, Air India’s India–UK routes operate under existing safety rules.
Why has the final report taken more than a year?
ICAO Annex 13 requires final reports “as soon as possible” but sets no hard deadline. Complex investigations involving multiple jurisdictions — in this case India, the US (Boeing and GE Aerospace), and the UK — routinely take 12–24 months. Analysis of the GE Aerospace engines and associated electronic controls has been conducted in France and the United States, extending the timeline. The 12-month threshold has now passed, triggering an obligation under Annex 13 for an annual interim statement if the final report is further delayed.
