Air India Flight 171 Crash: Investigation Sparks Controversy

A year since Air India Flight 171 crashed, India's investigation sparks controversy, with questions over pilot conduct, electrical failure, and corporate influence.

Air India Flight 171 crashed a minute after take‑off from Ahmedabad, killing 260 people. The Indian aircraft accident investigation bureau (AAIB) released a preliminary report that hinted at fuel‑cutting errors, but experts and families argue the real cause lies in a complex electrical failure. The report sparked intense backlash from safety campaigners, advocacy groups and the airline industry, raising doubts about the integrity of the inquiry and about Boeing's 787 Dreamliner safety record.

On 12 June 2025 a Boeing 787‑8 dreamliner destined for London plunged into the atmosphere less than a minute after leaving Ahmedabad airport, killing 260 of the 230 passengers on board and 19 people on the ground. The Indian Aircraft Accident Investigation Bureau (AAIB) released a 15‑page preliminary report that revealed the fuel‑cut switches were pulled seconds after take‑off and that the cockpit voice recorder captured a conversation suggesting an “unknown cockpit mishap.” The report’s silence about concrete causes, however, triggered a fierce backlash.

Safety advocates and pilot‑union officials argued that attributing blame to a dead captain deflects responsibility from aviation manufacturers and senior airline management. In response, the AAIB publicly condemned earlier media commentary that “exaggerated or misrepresented” the findings, urging the public to wait for the final report.

Competing explanations emerged. Some experts point to a major electrical failure that rebooted the aircraft’s flight‑management computer a few seconds after lift‑off, potentially making the engines think the aircraft was still on the ground and prompting an automatic fuel shutdown. Others maintain that the fuel‑cut switches were physically pulled, perhaps deliberately, as part of a pilot‑suicide theory that has generated accusations of homicide‑suicide.

A further wrinkle involves the Ram Air Turbine (RAT), an emergency propeller that began operating “within five seconds” of the fuel‑switch event, per the preliminary data. Simulations, however, suggest such rapid deployment is impossible and would normally occur 14–18 seconds after take‑off, implying the RAT may have engaged even before the engines were fully out of the air.

The airline and the Boeing 787 programme are both under scrutiny. Boeing has no history of major mis‑results for the 787, but the Evergreen Line has faced alarming reports of electrical faults and manufacturing defects. The Indian investigative board must publish an interim report by the anniversary and is under pressure from families, regulators, airlines and international bodies that increasingly demand clearer, more independent investigations.

While Boeing, the AAIB, and the Indian aviation authorities contend that the investigation is ongoing and transparent, the controversy points to a broader crisis: investigations in aviation accidents are still guided by decades‑old procedures that may not be adequate for today’s complex aircraft systems or the geopolitical environment that can influence findings. The debate continues as animation, survivor testimony, and expert analysis are being made public, reflecting the deep uncertainty over what truly caused the despair‑inflicted crash of Air India Flight 171.
