India's AAIB says Air India 171 crash inquiry is in final analysis
India's Aircraft Accident Investigation Bureau says its inquiry into Air India Flight 171 is in its final analysis stage, a year after the Boeing 787-8 crashed shortly after takeoff from Ahmedabad on 12 June 2025. The AAIB preliminary report states that both engine fuel control switches moved from RUN to CUTOFF seconds after liftoff, cutting thrust before the switches were moved back too late for recovery. The report did not assign blame or identify a final cause. Air India, Boeing and international investigators remain under scrutiny as families press for answers, while the Federation of Indian Pilots has challenged the probe's technical breadth and transparency. For Belgian and EU readers, the story is not about immediate local disruption; it is about confidence in global accident investigation, aircraft airworthiness oversight and the information passengers need after a mass-casualty aviation disaster.

About this story
Air India Flight 171 (scheduled Ahmedabad-London service that crashed on 12 June 2025) is the single accident under investigation. Air India (India's flag carrier, owned by Tata Group since 2022) operated the flight. India's Aircraft Accident Investigation Bureau (AAIB, civil aviation accident investigator under India's aviation ministry) leads the safety probe. Boeing 787-8 Dreamliner (long-haul twin-engine aircraft introduced in 2011) was the aircraft type. Sardar Vallabhbhai Patel International Airport (Ahmedabad's main airport in Gujarat) was the departure point. London Gatwick Airport (major airport south of London) was the destination. B.J. Medical College (Ahmedabad medical campus) was struck by the aircraft. Directorate General of Civil Aviation (India's aviation regulator) ordered post-crash checks. Federation of Indian Pilots (Indian pilots' association) is contesting aspects of the inquiry. Vishwash Kumar Ramesh (British passenger and sole onboard survivor) has called for clearer answers.
How to read this story
The history
The AAIB preliminary report places Flight 171 within the established post-crash model of factual findings first and conclusions later. The ICAO Annex 13 framework requires safety investigations to prevent recurrence rather than determine civil or criminal liability. The FAA's 2018 Special Airworthiness Information Bulletin, cited in reporting on the preliminary report, had warned of possible fuel-switch locking issues on some Boeing aircraft but did not make inspection mandatory. Earlier Boeing 787 scrutiny followed battery fires that led regulators to ground the type in 2013; Flight 171 was the type's first fatal hull-loss accident since service entry.
Why now
The story is timely because 12 June 2026 marks the first anniversary of the crash, families are again demanding answers, and India's AAIB says the inquiry is approaching final analysis without a published final cause.
What to watch
Watch for the AAIB final report, any safety recommendations to Air India, Boeing, engine or component suppliers, and any court action linked to families' claims or the pilots' association's demand for a broader probe.
International angle
This is a cross-border aviation story because the route connected India and the UK, the aircraft was made by Boeing in the United States, and international investigators and manufacturers have roles under accident-investigation protocols. The EU angle is indirect but real: European passengers, regulators and airlines depend on prompt sharing of safety-relevant findings from serious accidents anywhere in the connected aviation system.
What this means for you
There is no announced change for passengers in Belgium. The practical takeaway is to follow official regulator or airline notices, not speculation, if a final report produces safety recommendations. Travellers with disrupted or bereavement-related claims should rely on airline, insurer and legal documentation rather than preliminary media interpretations of fault.
What happens next
India's AAIB is expected to move from factual reconstruction to final conclusions, but the timing of publication remains uncertain. Investigators could issue safety recommendations if they identify a design, maintenance, training or procedural hazard. Families may continue civil claims or settlement negotiations, while pilots' representatives may keep pressing courts or aviation authorities for a broader technical review.
Potential consequences
If the final report identifies a mechanical, software or maintenance factor, regulators could require inspections, service bulletins or operational changes affecting Boeing 787 operators globally. If it concludes intentional or crew-related action, attention could shift toward cockpit mental-health screening, crew resource management and access to guarded controls. Either outcome could influence compensation disputes, airline trust and the speed at which accident data is shared internationally.
Opposing perspectives
- India's Aircraft Accident Investigation Bureau
The AAIB position is that the investigation should remain evidence-led until final analysis is complete. Its preliminary account identified the fuel-switch sequence and cockpit exchange but stopped short of blame, consistent with the ICAO safety-investigation model, which separates factual reconstruction from final causal findings.
- Federation of Indian Pilots
The Federation of Indian Pilots argues that the probe has focused too quickly on cockpit action while leaving technical questions insufficiently tested. The federation says encrypted aircraft health-monitoring data, avionics expertise and possible electrical issues should be examined before public debate settles on pilot responsibility.
- Affected families and survivor Vishwash Kumar Ramesh
Families and the sole onboard survivor argue that procedural caution cannot become silence. Their strongest case is that one year without clear answers deepens trauma, complicates compensation and legal choices, and leaves relatives unable to understand whether the disaster reflected human action, system design or oversight failure.

Glossary
- AAIB
- India's Aircraft Accident Investigation Bureau, the authority leading the Flight 171 safety investigation.
- DGCA
- India's Directorate General of Civil Aviation, the national aviation regulator.
- ICAO Annex 13
- International standards for aircraft accident and incident investigations, focused on preventing recurrence rather than assigning legal liability.
- Fuel control switch
- Cockpit control that opens or cuts fuel flow to an engine; on the Boeing 787 it is guarded against accidental movement.
- CUTOFF
- The fuel-switch position that stops fuel supply to an engine, causing loss of thrust.
