Air India AI-171 Probe Nears Completion, Says Minister

Finalizing the AI-171 Investigation

The investigation into the Air India AI-171 crash has reached its final stage, according to Union Civil Aviation Minister Kinjarapu Ram Mohan Naidu. The AAIB (Aircraft Accident Investigation Bureau) is currently finalizing its report regarding the June 12, 2025, disaster involving a Boeing 787-8 Dreamliner. The crash, which occurred shortly after take-off from Sardar Vallabhbhai Patel International Airport (AMD), resulted in 260 total fatalities, including 241 people on board and 19 individuals on the ground. Only one passenger survived the incident.

Minister Naidu emphasized that the investigation is proceeding in strict accordance with international protocols. "Our effort has always been to understand what happened, why it happened, and how it happened, rather than simply looking at the accident," the Minister stated. The bureau is adhering to the Aircraft (Investigation of Accidents and Incidents) Rules, 2017, as well as the standards and recommended practices under ICAO (International Civil Aviation Organization) Annex 13.

Judicial Scrutiny and Transparency

The investigation remains under the active oversight of the Supreme Court of India, which is currently hearing Writ Petition (Civil) No. 628/2025. This legal action stems from petitions seeking an independent, court-monitored inquiry into the crash. Victims' families and legal representatives have raised significant concerns regarding the transparency of the process, pushing for a comprehensive safety audit of the Air India fleet. The government has committed to submitting a final draft report in a sealed cover to the Supreme Court during the first week of October.

Technical Context and Preliminary Findings

A preliminary report released on July 12, 2025, documented that the aircraft's engine fuel control switches moved from the 'RUN' position to 'CUTOFF' shortly after take-off, leading to a loss of engine thrust. While this established a factual timeline, it did not identify a root cause. The probe has since involved complex simulation testing and analysis of the FADEC (Full Authority Digital Engine Control) systems. Analysts note that identifying whether the failure was systemic or human-induced remains the critical challenge for the final report.

Industry Trends and Regulatory Impacts

In the wake of the tragedy, the DGCA (Directorate General of Civil Aviation) mandated urgent inspections of 34 Boeing 787 aircraft in the Indian fleet. Furthermore, the Civil Aviation Ministry is now considering a proposal to increase mandatory annual pilot testing from 10% to 100% to bolster passenger safety standards. Historically, the 2010 Air India Express Flight 812 crash in Mangalore served as a precedent for such structural reforms, leading to the creation of the Civil Aviation Safety Advisory Council.

Pending Milestones

The Supreme Court has scheduled the next hearing for October 13, 2026. The court has decided to await the formal findings of the statutory investigation before determining if further inquiry, such as an independent committee, is required. The AAIB has urged patience, noting that the technical and international dimensions of the disaster require a rigorous, non-hurried process.

Why This Matters for Aviation Stakeholders

For Air India, the final report carries significant implications regarding potential liability under the Montreal Convention and long-term reputational risk. Simultaneously, the investigation into the 787-8's engine systems remains a high-stakes matter for Boeing and GE Aerospace, as any identified technical fault could trigger global airworthiness directives. For the broader industry, the outcome of this probe will likely set the tone for future regulatory oversight and pilot training requirements in India.
