Quick summary
One year after Air India flight AI171 crashed 32 seconds after takeoff from Ahmedabad on June 12, 2025, killing all 260 people on board and on the ground, India’s Aircraft Accident Investigation Bureau has still not published its final report. On the crash anniversary, the AAIB issued a second interim update confirming the probe remains in its “final analysis stage” with no definitive conclusions reached. Families of the 52 British nationals and 169 Indian nationals killed are publicly demanding answers over compensation.
India’s Civil Aviation Minister said in early May 2026 that the report would “mostly” be released within one month — that window has now closed. The only confirmed technical finding so far: both engine fuel control switches moved to CUTOFF within about one second of each other immediately after liftoff.
Twelve months after Air India flight AI171 went down into the BJ Medical College hostel complex in Ahmedabad, the families of 260 dead are still waiting for an official explanation. The Boeing 787-8, operating the Ahmedabad–London Gatwick route, lost power from both engines roughly 32 seconds after takeoff on June 12, 2025 — and the investigation that was supposed to tell the world why has yet to produce a final report.
On the first anniversary of the crash, India’s Aircraft Accident Investigation Bureau issued a second interim update. The AAIB confirmed the probe is in its “final analysis stage” and urged restraint on speculation. That is not the same as answers.
Mohammed Shoeb Iproliya, whose wife Nusratjahan Jethara was killed on the flight, told media he does not want money. He wants to know why it happened and who is responsible. That sentiment is shared across Leicester, where multiple families lost relatives on a flight that was supposed to land at Gatwick that afternoon.
The preliminary AAIB report established that both fuel control switches moved from RUN to CUTOFF within about one second of each other shortly after liftoff, cutting fuel to both GE GEnx-1B engines. One engine briefly showed signs of recovery before impact. No design flaw in the Boeing 787 or its engines was identified. What caused the switches to move — and whether that question has a definitive answer — remains officially unresolved.
What the investigation has — and hasn’t — established
India’s AAIB opened the formal investigation on the day of the accident under the Aircraft (Investigation of Accidents and Incidents) Rules, 2017, aligned with ICAO Annex 13 standards. The framework is methodical by design: safety-focused, non-punitive, and built to identify causes rather than assign criminal blame. Accredited representatives from the United States — via the NTSB and FAA — and the United Kingdom have participated alongside Indian investigators.
The preliminary report, released in July 2025, was detailed on sequence but silent on cause. Both fuel control switches moved to CUTOFF. Both engines lost power. One briefly recovered. The aircraft did not. What the preliminary report could not say — and what the AAIB still cannot say — is why the switches moved. Human factors, operational error, and mechanical interaction are all still on the table, at least publicly.
India’s Civil Aviation Minister stated in early May 2026 that the final report would “mostly” be released within one month. That timeline pointed to mid-June. The anniversary came and went. The AAIB’s second interim update, issued on the anniversary itself, confirmed the investigation is ongoing with no final conclusions ready — and the official government statement on the crash anniversary made no new commitment on timing.

Why the delay matters beyond the families
The AAIB’s rules require a preliminary report within 30 days and a final report “as soon as possible” — but for complex cases, there is no hard statutory deadline. Major accident investigations routinely run 12 to 24 months. By that measure, AI171 is not yet an outlier. The problem is the gap between official expectations and delivery: a minister’s public one-month commitment, now missed, raises questions that a procedural explanation does not fully answer.
For travelers, the practical consequence is a feedback loop that hasn’t closed. The preliminary report ruled out a 787 or GEnx-1B design flaw — that matters, because it means no airworthiness directive has been issued grounding or restricting similar aircraft. But without a final root-cause finding, regulators like the DGCA and FAA cannot mandate targeted fixes to training protocols, cockpit procedures, or specific operational practices. The system is designed to wait for that final report before acting. The report hasn’t come.
Sameer Rafik, whose cousin Faizan Rafik died on AI171, put it plainly: he wants to know whether thermal issues alone could have caused the crash, or whether something else was at fault. That is not an unreasonable question. It is, in fact, the central question the investigation exists to answer — and it remains open.
Steps for affected families and concerned travelers
The investigation remains open, the final report is overdue against the Minister’s own stated timeline, and families have no official channel through which to compel publication — which makes proactive monitoring and legal awareness the only practical tools available right now.
- Monitor AAIB and PIB directly: India’s Aircraft Accident Investigation Bureau publishes updates through the Ministry of Civil Aviation and the Press Information Bureau. Check both for any new interim statements or a final report release — do not rely on media summaries alone, which may lag or mischaracterize technical findings.
- UK families — follow the UK AAIB: The UK Air Accidents Investigation Branch participates as an accredited representative in the AI171 probe. Any safety recommendations affecting UK-registered aircraft or UK operations will be published on the UK AAIB site. Cross-reference with Indian AAIB updates.
- Understand the compensation framework: Standard passenger rights regimes — EU261/2004, UK261, US DOT delay rules — do not apply here. This was a fatal accident, not a delay or denial of boarding. Compensation claims for families fall under the Montreal Convention and carrier liability, pursued through Air India and civil courts under Indian law, with UK civil claims available for British victims.
- Consult aviation law specialists: Families seeking accountability beyond Air India’s stated support commitments should engage solicitors with specific experience in international aviation accident claims. The Montreal Convention sets liability frameworks, but civil litigation timelines and outcomes vary significantly by jurisdiction.
- Context on Air India’s current safety standing: For travelers weighing future bookings, understanding how safety investigations interact with airline certification is worth reading — the relationship between crash investigations and regulatory status is less straightforward than most assume, as covered in how aviation safety oversight actually works.
Watch: The formal publication of AAIB’s final AI171 report — if it arrives in late June or July 2026 as the Minister’s timeline implied, it will define the accepted cause and determine whether DGCA or FAA issue safety directives affecting 787 operations. If it slips again, expect sharper pressure from UK families and overseas regulators for an independent timeline commitment.
Questions? Answers.
What did the preliminary report actually find about why AI171 crashed?
India’s AAIB preliminary report, released in July 2025, found that both engine fuel control switches moved from RUN to CUTOFF within approximately one second of each other shortly after liftoff, cutting fuel to both GE GEnx-1B engines. One engine briefly showed signs of recovery before impact. The preliminary report did not identify a design or mechanical fault with the Boeing 787-8 or its engines. The cause of the switch movement — whether human factors, operational error, or another mechanism — has not been officially determined.
Is the Boeing 787 considered safe to fly following the AI171 crash?
No airworthiness directive has been issued restricting or grounding Boeing 787 aircraft as a result of the AI171 investigation. The preliminary AAIB report found no design flaw with the 787 or its GEnx-1B engines, and no manufacturer-specific safety recommendations were issued. Regulators including the FAA and EASA have not imposed operational restrictions on the type. The final report, when published, will determine whether any mandatory safety actions are required.
Can families of AI171 victims claim compensation under EU or UK passenger rights rules?
No. EU261/2004 and UK261 apply to flight delays, cancellations, and denied boarding — not to fatal accidents. Compensation for families of AI171 victims falls under the Montreal Convention and carrier liability frameworks, pursued through Air India and civil courts. UK-based families of British victims can also pursue civil claims in UK courts. Indian government ex gratia payments and support schemes are determined case-by-case by Indian authorities.
When is the final AAIB report on AI171 expected?
India’s Civil Aviation Minister stated in early May 2026 that the final report would “mostly” be released within approximately one month — a window that pointed to mid-June 2026. That deadline has passed without publication. On the crash anniversary, the AAIB confirmed the probe remains in its “final analysis stage” with no final conclusions reached. No new official publication date has been given. Based on the Minister’s statement, late June to early July 2026 remains the most recent official expectation.
