Air India Flight Crash – Flight 171 Cause, Survivor & Report

Air India Flight 171, a Boeing 787-8 Dreamliner registered as VT-ANB, crashed on June 12, 2025, just 32 seconds after takeoff from Ahmedabad’s Sardar Vallabhbhai Patel International Airport. The aircraft, bound for London Gatwick, struck a hostel building at the B.J. Medical College campus approximately 1.7 kilometres from the runway. The incident resulted in the deaths of 241 of the 242 people aboard, along with 19 individuals on the ground, making it the deadliest aviation disaster of the 2020s.

The crash triggered one of India’s largest emergency responses in recent aviation history. Emergency services arrived at the scene within minutes, where the aircraft had burst into flames after impact. One passenger survived the disaster, according to multiple sources documenting the incident. The Aircraft Accident Investigation Bureau launched an immediate inquiry, with authorities examining the aircraft’s maintenance history, flight data, and cockpit recordings.

This was the first hull loss involving a Boeing 787 since commercial operations began in 2011, and it represented Air India’s deadliest incident since the 1985 bombing. The Tata Group, which acquired Air India in 2022, subsequently offered compensation to affected families while the investigation continued to examine multiple possible causes.

What is the latest update on the Air India Flight 171 crash?

The Aircraft Accident Investigation Bureau released its preliminary report on July 12, 2025, presenting initial findings based on data from the aircraft’s enhanced flight recorders. The document traced the aircraft’s final moments, documenting critical switch positions and engine responses during the departure phase from Ahmedabad. Investigators confirmed they had recovered both black boxes from the wreckage and were analysing cockpit voice recordings alongside digital flight data.

• The aircraft had accumulated 41,868 airframe hours since its delivery to Air India in January 2014.
• Both GE GEnx-1B67 engines had been installed less than three months before the crash, with 28,000 and 33,000 hours respectively.
• The plane went down 32 seconds after becoming airborne, at 13:39 IST (08:09 UTC).
• A single passenger survived the crash, making this an extraordinarily rare outcome.
• The empennage detached during impact, with the aircraft striking a campus mess area.
• Preliminary technical assessments ruled out mechanical failure as the primary cause.
• Air India suspended 83 wide-body flights for six weeks following the accident.

What caused the Air India Flight 171 crash?

The AAIB preliminary report, published on July 12, 2025, documented a sequence of events that began just three seconds after takeoff. Both engines lost thrust after their fuel control switches transitioned from RUN to CUTOFF, according to data from the front enhanced airborne flight recorder. This finding represented the first major clue regarding what brought the aircraft down so shortly after departure from Ahmedabad airport. Aviation safety experts have noted that modern aircraft like the Dreamliner incorporate sophisticated automated systems that monitor and control engine functions, raising questions about potential electronic failures in the fuel control architecture.

Black box findings and cockpit recordings

The cockpit voice recorder captured dialogue between the pilots during the emergency. One crew member asked why the fuel supply had been interrupted, receiving the reply “I did not do so.” This exchange suggested confusion about the origin of the switch movement. Investigators examined whether the position changes occurred through deliberate action, a system malfunction, or an undetected mechanical fault.

In February 2026, Italian newspaper Corriere della Sera cited Western sources claiming that Captain Sumeet Sabharwal had intentionally moved the fuel switches to CUTOFF. These reports suggested a possible link to prior depression, though the Indian aviation authorities have not endorsed or confirmed this characterisation. An aviation expert interviewed on video proposed an alternative explanation, suggesting a chip malfunction could have triggered the switch movement without pilot involvement.

Official investigation status

The AAIB serves as the primary investigative body, with the DGCA conducting a parallel inquiry. The Directorate General of Civil Aviation had ordered enhanced inspections of Air India’s entire 787 fleet on June 13, covering fuel systems, engine controls, and oil checks. A preliminary technical assessment ruled out conventional mechanical failure, though investigators continued to examine electronic and automated systems as potential contributing factors.

Political considerations reportedly influenced the timing of any formal announcement, with pilot associations having protested earlier leaks that appeared to assign blame to cockpit crew. The Tata Group, owner of Air India since 2022, offered compensation of 1 crore INR (approximately $115,000) per victim family while seeking no-sue settlement agreements.

Who survived the Air India Flight 171 crash?

One passenger survived the crash of Air India Flight 171, making this outcome statistically exceptional given the scale of the disaster. The individual was found among the wreckage and transported to medical facilities where treatment began immediately. Detailed information about the survivor’s identity, condition, or the specific circumstances that allowed them to survive has not been widely reported in available sources.

The survival of even a single passenger from an incident of this magnitude represents a rare occurrence in aviation history. Among 242 people aboard the Boeing 787, only this one individual escaped the immediate consequences of the impact and post-crash fire. Ground casualties included 19 fatalities and 67 injuries, according to documentation from the crash site.
