The Aircraft Accident Investigation Bureau (AAIB) told the Supreme Court on Tuesday that a draft final report into the June 12, 2025 Air India flight AI‑171 crash is expected in October, court submissions and news reports show. Investigators say they have completed or advanced major technical work — including preparation of a cockpit voice/data‑recorder transcript and human‑factors reviews — and have moved into the final stages of the probe. Families of victims have publicly pressed the AAIB for simulator testing and clearer deadlines, while government lawyers and the Civil Aviation Ministry maintain the investigation is proceeding as per procedure.
Where the investigation stands
AAIB officials told the Supreme Court the probe has entered its final phase after analysts prepared cockpit‑recorder transcripts and completed human‑factors reviews, court filings and news organizations reporting from those filings say. The agency is working to finalize technical analyses and draft conclusions before assembling the draft final report.
AAIB published interim paperwork and a preliminary factual report earlier in the probe, but the full draft that typically contains analysis, probable cause and safety recommendations remains under preparation. Investigators have described several external dependencies that could affect timing as they coordinate with foreign authorities and outside experts.
Families and legal challenges
Relatives of those killed in the crash and pilot groups have sought more transparency and additional investigative steps, including simulator tests to reconstruct the sequence of events. Petitioners in the Supreme Court have asked the court to oversee aspects of the probe, while other parties have urged the AAIB to consider independent analyses submitted by outside experts.
Those demands have increased public scrutiny and pressured investigators as timetables shifted. AAIB and government lawyers have opposed calls for a separate judicial inquiry, saying the statutory investigation remains the appropriate forum for technical findings.
Timeline questions and what to watch next
The October timing was described in court submissions and reported by multiple outlets as an expected or target month for a draft final report; reporting varies on whether that date is a firm deadline or an operational estimate dependent on outstanding technical work.
Key public milestones include whether AAIB files a formal court document or transcript that fixes an exact delivery date; whether the agency discloses whether simulator tests were conducted and, if so, who ran them; and whether AAIB releases or summarizes primary records such as CVR/FDR transcripts, ATC recordings or maintenance logs.
Publication of the draft report — even in sealed form to the court — or a new interim statement would substantially reduce current uncertainty.
