AAIB Delays Final Report on AI‑171 Crash as Engine Tests Continue

Investigators say detailed overseas tests of engines, including engine‑management systems, must finish before a final report is issued.

Overview

  • The crash, which occurred on June 12, 2025, killed 260 people when a Boeing 787‑8 lost thrust seconds after takeoff from Ahmedabad and struck a hostel; one passenger survived.
  • AAIB will not publish a final report on the one‑year mark because forensic teardown and specialist analysis of GE engines and engine‑management units in US and French facilities remain incomplete.
  • AAIB’s July 2025 preliminary findings showed both engine fuel‑control switches moved to CUTOFF within about one second and recorded a brief cockpit exchange questioning why fuel had been cut, findings that have not produced a definitive cause.
  • Pilot groups and some relatives reject a focus on crew action and have sought a judicial probe while Air India and Tata have made interim payments to most families but face ongoing demands for black‑box transparency and fuller accountability.
  • The probe’s technical complexity and cross‑border testing mean a final report is now expected months away and could reshape regulatory, legal and reputational outcomes for Air India, Boeing and GE.
