Air India Crash: How US Golden Chassis Helped Recover 49-Hour Flight Data, 2-Hour Audio
Last Updated: The Air India-171 crash report was released on Saturday, revealing the cause of the crash on June 12. A Golden Chassis from the United States played a key role in downloading 49 hours of flight data from one of the black boxes of the ill-fated Air India-171 plane, which crashed on June 12, killing all but one on board. After the crash in Ahmedabad, the Aircraft Accident Investigation Bureau (AAIB) retrieved two black boxes and brought them to New Delhi on June 24 for decoding purposes. Usually, to get data from damaged flight recorders, investigators borrow a 'Golden Chassis" and the needed download cables from other agencies that handle air crash investigations. In the ongoing investigation, AAIB said on Saturday that the Golden Chassis, or the identical EAFR unit, and download cables, which were needed to download data from Enhanced Airborne Flight Recorders (EAFRs) were sourced from the US National Transport Safety Board (NTSB). The data download from the front EAFR was tried at the AAIB Lab in the national capital on June 24. The Crash Protection Module (CPM) was taken out of the forward EAFR and was found to be in good condition. 'The CPM was mounted on the Golden Chassis, and the raw data was downloaded from the EAFR. The downloaded flight data contained approximately 49 hours of flight data and 6 flights, including the event flight. The recovered audio was two hours in length and captured the event. Initial Analysis of the recorded audio and flight data has been done," AAIB said in its preliminary probe report released yesterday. The report said that the aft EAFR was significantly damaged and could not be downloaded using conventional methods. The CPM was opened to check out the memory card, which suffered extensive damage. Meanwhile, Sanjay Kumar Singh has been named the Investigator-in-Charge, and Jasbir Singh Larhga is the Chief Investigator. Vipin Venu Varakoth, Veeraragavan K, and Vaishnav Vijayakumar are part of the investigation team. To support the investigation, experts in flying, aircraft engineering, aviation medicine, aviation psychology, and flight recorder analysis have also been brought in.

Air India Ahmedabad plane crash: U.S. Golden Chassis helped AAIB download raw data from black box
A Golden Chassis from the United States helped download 49 hours of flight data from one of the black boxes of Air India's ill-fated Boeing 787-8 aircraft that crashed last month. After the fatal accident that destroyed the aircraft and killed 260 people on June 12, the Aircraft Accident Investigation Bureau (AAIB) retrieved the two black boxes or Enhanced Airborne Flight Recorders (EAFRs) and brought them to the national capital on June 24. Generally, data from damaged flight recorders is downloaded after sourcing Golden Chassis and relevant download cables from other accident investigation authorities. In the current investigation, AAIB on Saturday (July 12, 2025) said the Golden Chassis or the identical EAFR unit and download cables required to download data from EAFR were sourced from the U.S. National Transport Safety Board (NTSB). The download from the FWD EAFR was attempted at the AAIB Lab in the national capital on June 24 and the Crash Protection Module (CPM) was retrieved from the forward EAFR and found to be in good condition. "The CPM was mounted on the Golden Chassis and the raw data was downloaded from the EAFR. The downloaded flight data contained approximately 49 hours of flight data and 6 flights, including the event flight. "The recovered audio was two hours in length and captured the event. Initial Analysis of the recorded audio and flight data has been done," AAIB said in its preliminary probe report on the plane accident. According to the report, the aft EAFR was substantially damaged and could not be downloaded through conventional means. The CPM was opened to inspect the memory card. The damage was extensive, it added. Meanwhile, Sanjay Kumar Singh has been appointed as the Investigator-in-Charge, while Jasbir Singh Larhga is the Chief Investigator. Vipin Venu Varakoth, Veeraragavan K and Vaishnav Vijayakumar are the Investigators. Experienced pilots, engineers, aviation medicine specialists, aviation psychologists and flight recorder specialists have been taken on board as subject matter experts to assist in the probe.

Air India crash report: 49 hours of raw data retrieved from black box using US ‘Golden Chassis'
A 'Golden Chassis' sourced from the United States enabled the successful download of 49 hours of flight data from one of the black boxes of Air India's Boeing 787-8 aircraft that crashed in Ahmedabad on June 12, claiming 260 lives. Wreckage of Air India Flight 171, a Boeing 787-8 Dreamliner aircraft, one month after the crash in Ahmedabad.(PTI) The Aircraft Accident Investigation Bureau (AAIB) had retrieved the Enhanced Airborne Flight Recorders (EAFRs), commonly referred to as black boxes, and transported them to New Delhi on June 24. Typically, when flight recorders are damaged in an accident, investigators rely on a Golden Chassis—an identical recording unit—and compatible download cables sourced from other international agencies to extract data. In this case, the AAIB confirmed on Saturday that the 'Golden Chassis' and the necessary download cables to access data from the EAFR were provided by the US National Transportation Safety Board (NTSB). The data extraction from the forward EAFR was attempted at the AAIB laboratory in New Delhi on June 24. Investigators found the Crash Protection Module (CPM) intact and in good condition. 'The CPM was mounted on the Golden Chassis, and the raw data was downloaded from the EAFR. The downloaded flight data contained approximately 49 hours of flight data and 6 flights, including the event flight,' AAIB said in its preliminary probe report on the crash. 'The recovered audio was two hours in length and captured the event. Initial Analysis of the recorded audio and flight data has been done,' the report added. The report noted that the aft EAFR had suffered significant damage and could not be accessed using standard procedures. Investigators opened the CPM to inspect the memory card but found the damage to be extensive. The investigation is being led by Sanjay Kumar Singh, who has been appointed as the investigator-in-charge. Jasbir Singh Larhga is serving as the chief investigator. The investigation team also includes Vipin Venu Varakoth, Veeraragavan K, and Vaishnav Vijayakumar. To support the technical and operational aspects of the probe, the AAIB has roped in experienced pilots, engineers, aviation medicine specialists, aviation psychologists, and flight recorder experts as subject matter specialists.

Air India plane crash report: How 'Golden Chassis' helped AAIB get raw data from black box
A Golden Chassis is a specialised tool used to recover data from damaged flight recorders. It consists of an identical, undamaged unit of the same model as the affected recorder and is used to interface with its internal memory read more The tail of an Air India Boeing 787 Dreamliner plane that crashed is seen stuck on a building after the incident in Ahmedabad, India, on June 12. In the aftermath of the crash, Air India continues to cancel several flights. Reuters A highly specialised tool from the United States known as a Golden Chassis helped Indian investigators retrieve critical data from one of the black boxes of Air India's Boeing 787-8 aircraft that crashed last month, killing 261 people. The Aircraft Accident Investigation Bureau (AAIB) said Saturday (July 11) that the tool enabled the recovery of approximately 49 hours of flight data and two hours of cockpit audio, including information from the crash itself. STORY CONTINUES BELOW THIS AD The aircraft, bound for London, came down seconds after take-off from Ahmedabad on June 12. Investigators retrieved the two Enhanced Airborne Flight Recorders (EAFRs) and transported them to New Delhi on June 24. The forward black box, or EAFR, remained sufficiently intact for a download attempt at the AAIB lab. The aft recorder, however, was too badly damaged to yield data by conventional methods. How the Golden Chassis works A Golden Chassis is a specialised tool used to recover data from damaged flight recorders. It consists of an identical, undamaged unit of the same model as the affected recorder and is used to interface with its internal memory, known as the Crash Protection Module (CPM). When a recorder is too damaged to power up or connect directly, investigators remove the intact CPM and mount it onto the Golden Chassis. This allows for safe extraction of flight and cockpit voice data. In this case, the required chassis and cables were sourced from the US National Transportation Safety Board (NTSB). Once the forward CPM was mounted onto the Golden Chassis, flight and audio data from six flights, including the doomed one, were successfully downloaded. 'The recovered audio was two hours in length and captured the event. Initial analysis of the recorded audio and flight data has been done,' the AAIB said in its preliminary report. Ongoing investigation The aft EAFR was found to be too extensively damaged to yield any data using standard procedures. The CPM from the aft unit was removed, but the memory card was also found to be severely compromised. The AAIB has appointed Sanjay Kumar Singh as Investigator-in-Charge, with Jasbir Singh Larhga named Chief Investigator. Additional investigators include Vipin Venu Varakoth, Veeraragavan K and Vaishnav Vijayakumar. STORY CONTINUES BELOW THIS AD A team of subject matter experts, including experienced pilots, engineers, aviation medicine specialists, aviation psychologists, and flight recorder specialists, has also been assembled to assist with the inquiry.
