The Indian agency investigating last year’s Air India plane crash that killed 260 people has said a draft final report could be ready in October.

The Aviation Accident Investigation Bureau (AAIB) told the Supreme Court in an affidavit filed on Tuesday that it was currently “engaged in the analysis phase” of the investigation, which is expected to conclude in about six weeks.

The affidavit did not say when the report would be made public or reveal any findings related to the crash.

The tragedy occurred on June 12, 2025, when an Air India Boeing 787 Dreamliner heading to London crashed seconds after taking off from Ahmedabad airport in western India.

The plane fell about 6 kilometers (3.7 miles) from the airport, crashing into a building used as accommodation for doctors at a medical school, causing an explosion.

In total, 260 people, 241 on board and 19 on the ground, died in the accident. Only one passenger, Viswashkumar Ramesh, from Leicester, survived.

The AAIB launched an investigation shortly after the accident and published a preliminary report a month later.

An update published on the first anniversary of the crash said “significant progress” had been made in analyzing the evidence, but gave few other details.

In Tuesday’s affidavit, the AAIB said it had taken 49 of 66 mandatory actions to investigate any serious air accident.

This included examining the crash site and wreckage of the plane; collect evidence, including flight recorders; and review relevant records, including crew members’ medical history and training records.

“A review of organizational culture, human factors, and safety practices was conducted. An autopsy and psychological evaluation were performed and the psychologist’s final report was received,” the affidavit says.

A psychological autopsy suggests that investigators asked an aviation psychologist to evaluate the psychological profile of one or more crew members as part of a broader human factors investigation.

The affidavit also stated that he had prepared a transcript of the cockpit voice recorder, but did not reveal any further details.

The preliminary report released last July said that just seconds after takeoff, the fuel control switches were abruptly moved to the “cut-off” position, starving the engines of fuel and causing a complete loss of power.

Cockpit audio recordings captured one pilot asking the other why he did it, and the other responded no. The report did not identify which pilot made any of the statements.

The ambiguity in the report led to speculation about the pilots’ role in the crash, and some foreign media reports said investigators were turning their attention to the lead pilot in the cockpit: Captain Sumeet Sabharwal.

The reports sparked strong reaction from Sabharwal’s father, the pilots’ associations of India and the AAIB, which criticized the coverage.

In the affidavit, filed in response to a complaint by Sabharwal’s father seeking an independent probe into the crash, the AAIB said “media speculation and narratives attributing culpability to the pilots have unfortunately caused some witnesses to become restrictive and unresponsive.”
