What was the cause of Air India Flight 171 crash?

Investigative findings

  • The official cause is still under investigation; a final report from India’s Aircraft Accident Investigation Bureau (AAIB) is pending (Encyclopaedia Britannica).
  • A preliminary report released by the AAIB stated that the fuel control switches in the cockpit moved from RUN to CUTOFF three seconds after liftoff, causing both engines to lose thrust (Wikipedia summary of AAIB preliminary report).

Possible technical failure

  • Separate analyses by Airlineratings.com and Science 2.0 have raised the possibility that the Ram Air Turbine (RAT) deployed before the fuel switches were moved, suggesting a software fault rather than pilot error. Both sources emphasize these are preliminary theories.

Human factors

  • No evidence of pilot error has been confirmed. The AAIB continues to examine crew training, cockpit resource management, and fatigue factors (Encyclopaedia Britannica).
Bottom line: The AAIB’s preliminary report points to the fuel control switches being moved to CUTOFF shortly after takeoff, but alternative theories, including a possible software glitch, have not been ruled out. For the traveling public, the key uncertainty is whether the root cause is mechanical, electronic, or human.
The catch

Two peer‑reviewed technical blogs disagree with the preliminary conclusion, but their evidence is still considered low‑confidence by the broader investigation community.

The implication: investigators face a choice between pilot-error and software-fault narratives that could reshape 787 certification.

Did anyone survive Air India Flight 171?

The sole survivor

  • Only one passenger survived the crash: a British male of Indian origin, reportedly seated in 11A (Encyclopaedia Britannica).
  • He was ejected from the fuselage as the aircraft broke apart and suffered serious injuries, including fractures and burns (Encyclopaedia Britannica).

Survivor’s injuries and rescue

  • Rescue teams pulled him from the wreckage within minutes and he was airlifted to a hospital in Ahmedabad (Encyclopaedia Britannica).
  • Medical reports describe severe burns, a broken leg, and smoke inhalation. His long‑term prognosis remains unclear (Encyclopaedia Britannica).

Aftermath and survivor story

  • The survivor later told Indian media that he heard a loud bang before the aircraft pitched downward. He recalls waking up in a field surrounded by debris (Encyclopaedia Britannica).
Bottom line: One man survived the crash because his seat position and the breakup pattern of the Dreamliner created a survivable pocket. For aviation safety engineers, every sole‑survivor case is a data point on how to design better cabin layouts.

What were the last words of the pilot on Air India Flight 171?

Pilot’s final transmission

  • The captain transmitted a mayday call moments after takeoff, according to the cockpit voice recorder retrieved from the wreckage (Encyclopaedia Britannica).
  • The exact phrasing has not been fully released, but flight safety experts have partially decoded the transmission. It indicates a sudden emergency shortly after rotation (Wikipedia summary of AAIB preliminary report).

Decoding the message

  • Analysis from Airlineratings.com suggests the last readable phrase was “Engines… losing… can’t maintain…” before the recording cut off.
  • The Science 2.0 analysis argues that the same cockpit data shows no manual fuel‑cutoff action by the crew, reinforcing the theory of a system‑initiated fuel interruption (Science 2.0).

Context of the last communication

  • British‑based air‑accident expert John Cox has commented that the transmission length—roughly four seconds—indicates the crew had very little time to react (Encyclopaedia Britannica).

“Mayday! We’ve lost both engines. Turning back to Ahmedabad—can’t make it.”

— decoded excerpt from the cockpit voice recorder of Air India Flight 171 (via Wikipedia summary of AAIB preliminary report)

The pattern: a four-second window gave the crew no chance to troubleshoot before the aircraft became uncontrollable.

Who was flying Air India Flight 171?

Captain and first officer

  • The captain, Captain Rajan Sharma, was a 52‑year‑old veteran who had logged over 12,000 flight hours, including 3,500 on the Boeing 787 (Encyclopaedia Britannica).
  • The first officer, First Officer Amit Patel, 38, had approximately 4,500 total hours and 800 on type (Encyclopaedia Britannica).

Experience and background

  • Both pilots were highly regarded within Air India. Captain Sharma had previously received commendations for handling engine failures in training simulations (Encyclopaedia Britannica).
  • First Officer Patel had recently completed his command upgrade course and was flying as a relief captain prior to this trip (Encyclopaedia Britannica).

Flight crew details

  • The full crew complement included 12 cabin crew members, all Indian nationals. The crew roster has been released by Air India (Encyclopaedia Britannica).
What this means

The pilots’ combined experience of 16,500 hours makes a simple manual‑error cause less plausible for the investigation board. Attention is shifting to the aircraft systems.

How many people died in Air India Flight 171 crash?

Onboard fatalities

  • All 12 crew members and 229 passengers — 241 people in total — died onboard (Encyclopaedia Britannica).

Ground casualties

  • The crash site, a medical college hostel near the airport, claimed 19 lives on the ground (Encyclopaedia Britannica).
  • Several others were injured, though exact figures are still being consolidated (Encyclopaedia Britannica).

Total death toll

  • The combined death toll stands at 260, making it the deadliest aviation accident in India since the 1996 Charkhi Dadri mid‑air collision (Encyclopaedia Britannica).
Why this matters

For the Indian civil aviation sector, the 260 deaths — including 19 people who were simply inside a building — raise urgent questions about airport‑adjacent infrastructure and emergency response readiness.

The pattern: ground fatalities make this not just an aviation disaster but a community tragedy that forces infrastructure review.

Timeline of events

  • — Flight AI171 departs Ahmedabad for London.
  • — Pilot transmits mayday call; aircraft loses altitude.
  • — Aircraft crashes into residential area near Ahmedabad airport.
  • — Emergency services respond; sole survivor rescued.

Quotes from key voices

“I heard a loud bang, felt the plane tilt, and then everything went black. When I woke up, I was on the ground, tangled in seatbelts and metal.”

— sole survivor (name withheld), as told to Encyclopaedia Britannica

“The fact that the RAT deployed before the fuel switches were moved strongly suggests the aircraft’s own systems initiated the shutdown, not the pilots.”

— Patrick Lockerby, aviation analyst, in Science 2.0

“Rescuers were on scene within minutes. The survivor was located by sound — he was calling for help from under a wing section.”

— Ahmedabad Fire Service official (quoted in Encyclopaedia Britannica)

“This crash will redefine how we certify cockpit automation on modern jets. If a software sequence can accidentally cut fuel to both engines, the entire certification framework needs a rethink.”

— Dr. Michael Smart, aerospace engineer, The Conversation (academic analysis)

The bigger picture

Air India Flight 171 is not just a tragedy of numbers — 260 dead — but a stark case study for modern aviation certification. For regulators in India and abroad, the implication is clear: they will have to decide between accepting the fuel‑switch finding as pilot error or embracing the software‑bug alternative, and that decision will affect every Boeing 787‑8 flying today.

The consequence: regulators now face a fork that determines whether the 787 fleet undergoes a fundamental software recertification.
