Summary of Why the Air India B787-8 (VT-ANB) Crash Happened – Preliminary Report
Flight: AI171 from Ahmedabad to London Gatwick Date: XX June 2025 Crash Location: XXX NM from runway end at Ahmedabad Fatalities: XXX (all onboard + XX on ground)
⸻
🔧 Key Cause – Accidental Engine Shutdown During Takeoff •Takeoff was normal until liftoff at 08:08:39 UTC, with both engines at takeoff thrust. •Just X seconds after liftoff, both fuel control switches transitioned from RUN to CUTOFF within X second of each other, cutting fuel to both engines. •Both engines shut down mid-air, causing immediate loss of thrust.
One pilot is heard asking, “Why did you cutoff?” The other responded, “I did not.”
This suggests neither pilot intended to shut down the engines, and it may have been accidental or due to a system fault.

🔄 Attempted Recovery (Too Late) •Ram Air Turbine (RAT) deployed automatically, indicating total engine power loss. •Within 5–7 seconds, pilots tried to restart both engines by moving fuel switches back to RUN. •Engines began relight, with Engine X showing some signs of recovery. •However, the aircraft was already too low, lost altitude rapidly, and crashed into nearby buildings.
⸻
🧩 Other Details Supporting the Sequence •Aircraft was well within takeoff weight limits. •Weather was clear, and no bird strike or major mechanical failure was reported. •Throttle levers were physically found in idle (due to impact), but data showed they were in takeoff position until crash. •No autopilot or autothrottle fault reported. •Cockpit audio and data confirm that shutdown was sudden and unintended.
