India’s Civil Aviation Ministry informed the Rajya Sabha that advanced OEM-level tests by Boeing on the AI 171 Dreamliner’s fuel control switch and its detents showed no structural abnormalities. The finding narrows the probe’s technical angles while the Aircraft Accident Investigation Bureau continues examining the thrust control module and pilot actions ahead of an October 2026 final report on the fatal Ahmedabad crash.
WITH JUST A COUPLE MONTHS PENDING in release of the final report that would reveal the reason behind the tragic crash of the Air India AI 171 Flight that happened on June 12, 2025, the Centre has given another update regarding the investigation. As the probe enters into its final stage, the Centre has informed the parliament that no fault was found in the Boeing 787-8 Dreamliner aircraft’s fuel control switch or in its locking mechanism.
On Wednesday, July 29, 2026, as the Parliament’s monsoon session was underway, Minister of State for Civil Aviation Murlidhar Mohol said in the Rajya Sabha that advanced tests conducted by aircraft manufacturer Boeing found the fuel control switch to be functioning normally. The fuel control switch was examined at the Original Equipment Manufacturer (OEM) level in Seattle, United States, as part of continued airworthiness checks ordered by the Directorate General of Civil Aviation (DGCA).
The AI 171 flight was a Boeing 787-8 Dreamliner aircraft that crashed 32 seconds after its takeoff from Gujarat’s Ahmedabad airport. The tragic incident happened on June 12, 2025, claiming 260 lives.
Congress MP Jebi Mather Hisham raised questions in the Upper House about the government's delay in publishing the final report of the Aircraft Accident Investigation Bureau (AAIB), the attached office of the DGCA tasked with investigating the reason behind the AI 171 flight crash. In response, Mohol remarked that “no abnormalities” were found in the “structural integrity” of the fuel control switch. However, the investigation into the aircraft’s complete Thrust Control Module is still underway at the Boeing’s facility in Seattle. Mohol said the findings from that inspection are still awaited.
Directorate General of Civil Aviation (DGCA), as part of continued airworthiness, directed Original Equipment Manufacturer (OEM) level testing of Fuel Control Switch Locking Mechanism in Seattle. Detailed examination of Fuel Control Switch including structural integrity of Fuel Control Switch detents was carried out and no abnormality was observed.Murlidhar Mohol, Minister of State for Civil Aviation
MP Mather also raised queries about the government's delay in the release of the AAIB crash report, asking whether pilot conduct was among the factors under scrutiny and whether a concrete public release date could be announced. Mohol maintained the centre’s stance and stated that there is no delay in the release of the report. The minister further said that investigation into major accidents, such as the Air India 171 fight crash, are dependent on several factors and as such a concrete release date cannot be determined.
Mohol said that once the investigation is complete, the final report will be publicly accessible and would be published on the AAIB’s website.
A few weeks after the AI 171 flight crash, the AAIB released a preliminary report of its findings. The report found that the aircraft's fuel control switch was abruptly moved from RUN to CUTOFF a few seconds after takeoff. This prevented fuel flow to the engines and caused their shutdown.

Cockpit voice recording of the aircraft detailed a brief exchange between the airplane’s two pilots, First Officer Clive Kunder and Pilot-in-Command Captain Sumeet Sabharwal. One of the pilots — unclear whether it was Kunder or Sabharwal — asked the other why he moved the fuel control switch, to which the other replied “I did not.” This revelation raised doubts about whether the plane crash happened due to technical difficulties or due to human error.
Mohol said the investigation remains under way and that all possible causes and contributing factors are being examined. “All probable causes and contributing factors leading to the accident are being investigated,” Mohol said in the Parliament.
This update comes weeks after the AAIB, in an affidavit to the Supreme Court, stated that its investigation into assessing the reason behind the AI 171 flight crash is "expected to be completed within six weeks.” The AAIB also stated that the final draft report will be ready by October 2026.
