Unknown Apr 02, 2026 800 Views

The Aircraft Accident Investigation Bureau (AAIB) has submitted its preliminary report on the tragic crash of Air India Flight AI-171 to the Ministry of Civil Aviation and other relevant authorities. The report, mandated under ICAO norms within 30 days of an accident, follows the June 12 crash of the Boeing 787 Dreamliner shortly after takeoff from Ahmedabad, which claimed 260 lives, including 241 onboard and 19 on the ground.

Key Developments:

The AAIB recovered both black boxes—Cockpit Voice Recorder (CVR) and Flight Data Recorder (FDR)—on June 13 and 16, respectively, from the crash site near B.J. Medical College.

Data extraction began on June 24 at the AAIB lab in Delhi, with successful downloads completed by June 25.

The preliminary report includes a timeline of the final 32 seconds of flight, pilot control inputs, cockpit conversations, ATC communications, and weather data.

The report does not assign blame or determine the root cause but aims to reconstruct the sequence of events and identify contributing factors.

Investigation Status:

The AAIB formed a multidisciplinary team on June 13, including aviation medicine experts, ATC officers, and representatives from the U.S. NTSB.

Criticism has emerged over delays in formally institutionalizing the probe panel and appointing a lead investigator.

The possibility of sabotage is being examined, alongside mechanical failure, human error, and system malfunction.

Outlook: The final report, expected in several months, will be crucial in shaping global aviation safety protocols, especially for Boeing 787 operations. Meanwhile, the aviation community awaits further clarity as the investigation deepens.
