Air India AI‑171 Final Report Delayed as Engine Analysis Continues

Investigators will publish an interim status update because specialized testing of the aircraft’s engines and engine‑management electronics in overseas facilities is not yet finished.

Overview

  • The London‑bound Boeing 787 that crashed after takeoff from Ahmedabad on June 12, 2025 killed about 260 people and left one survivor, and investigators say the one‑year deadline for a final report cannot be met.
  • India’s Aircraft Accident Investigation Bureau is withholding a final report and plans an interim statement because GE Aerospace engine parts and the engine‑management unit are still being examined in U.S. and French facilities.
  • The AAIB’s July 2025 preliminary report recorded both engine fuel‑control switches moving from RUN to CUTOFF seconds after takeoff and a brief cockpit voice exchange; RUN means fuel flows to the engines and CUTOFF means fuel supply is stopped.
  • The Federation of Indian Pilots and relatives of the captain have demanded a judicial or independent probe and urged authorities not to release partial findings that they say risk fueling speculation about pilot action versus technical or electrical failure.
  • The delay highlights wider capacity strains in India’s safety system because many serious‑incident final reports remain pending and under ICAO rules investigators must issue yearly progress updates when a final report exceeds 12 months, leaving families waiting for full answers and safety recommendations.
