Air India flight 171 crash fuels dispute over cause

In 2025 a Boeing 787 Dreamliner departed from Ahmedabad airport for London and crashed within a minute of take‑off, killing 260 people on board and 19 on the ground. The official investigation by India’s Aircraft Accident Investigation Bureau has sparked controversy ranging from claims of pilot misconduct to allegations of manufacturing flaws.

Preliminary findings suggest deliberate pilot action

The flight data recorder shows the fuel cutoff switches moving from the run to the cutoff position shortly after the aircraft began its climb. A cockpit voice recording, albeit without transcript, reveals a pilot questioning the other about the switch, with the answer indicating no action was taken by the questioned pilot. Some media outlets have leveraged this to argue that the captain intentionally shut the engines.

Electrical‑failure theory offers alternate explanation

Safety campaigners argue that a sudden reboot of the aircraft’s main flight computers could mis‑interpret the plane as being on the ground, prompting an emergency sequence that cuts the fuel supply. They also point to a rapid deployment of a Ram Air Turbine that would normally take 14–18 seconds, yet was observed within five seconds of the fuel‑cut action, indicating it may have deployed earlier than expected.

Industry and regulatory response

Boeing, which supplied the aircraft and its engines, has advised India’s investigators gather all available data before making conclusions. The manufacturer maintains that the 787 has an excellent safety record, while critics worry that high‑profile accidents erode public trust.

India’s civil aviation minister announced that the final investigation will be released on the anniversary of the crash, yet many observers doubt that the report will reconcile the diverging theories.

Broader implications for investigative processes

The Air India crash highlights long‑standing concerns about political influence in national investigations and the possibility of manufacturers defending against liability. Recent changes to ICAO Annex 13 will allow countries to delegate investigations to external bodies, but it remains to be seen whether this will address the deep mistrust seen in this case.
