Extraction and evaluation of information from the black containers of the ill-fated Air India Boeing 787-8 plane that crashed in Ahmedabad on June 12 is being completed on the Plane Accident Investigation Bureau’s (AAIB) new state-of-the-art laboratory in Delhi, in accordance with the Ministry of Civil Aviation (MoCA). The black containers are essential in plane accident investigations as they supply information on scores on parameters and plane techniques, serving to the investigators establish the most definitely causes of an accident.
MoCA additionally stated that the AAIB “promptly initiated” an investigation and constituted a multi-disciplinary crew following the tragic crash of Air India flight AI171 in Ahmedabad. This crew, constituted as per worldwide protocol, is led by AAIB Director Normal GVG Yugandhar, and contains an aviation drugs specialist, an air visitors management officer, and representatives from the US Nationwide Transportation Security Board (NTSB). The NTSB is helping the AAIB within the probe because the plane was designed and manufactured within the US by an American firm—Boeing.
“On the night of 24 June 2025, the crew led by DG (director normal) AAIB with technical members from AAIB and NTSB started the info extraction course of. The Crash Safety Module (CPM) from the entrance black field was safely retrieved, and on 25 June, 2025, the reminiscence module was efficiently accessed and its information downloaded on the AAIB Lab,” MoCA stated Thursday in an official launch, offering an replace on the restoration and examination of black field information.
“The evaluation of CVR (cockpit voice recorder) and FDR (flight information recorder) information is underway. These efforts purpose to reconstruct the sequence of occasions resulting in the accident and establish contributing components to reinforce aviation security and stop future occurrences. All actions have been taken in full compliance with home legal guidelines and worldwide obligations in a time certain method,” the ministry added.
There have been studies and hypothesis that the black field—FDR and CVR—may very well be despatched to the US as AAIB’s black field lab may not be totally outfitted to deal with broken items. Sources had indicated that there have been deliberations on whether or not to ship items to the NTSB Automobile Recorder Laboratory within the US for information extraction and evaluation, or carry out the train on the AAIB’s new black field lab in Delhi. Whereas the federal government had earlier stated that the choice on the place to extract and analyse information can be taken by the AAIB, the NTSB had declined to touch upon the potential of the black containers being taken to the US.
“The investigation is being led by India’s Plane Accident Investigation Bureau. As stipulated by worldwide treaty (ICAO Annex 13) the nation main the investigation is the entity to launch any details about the investigation. I’d counsel reaching out to them,” an NTSB spokesperson had stated on Wednesday in response to queries from The Indian Categorical.
Boeing 787 plane have two mixed black field units, every with the joint capabilities of CVR and DFDR. In keeping with business insiders, the mixed black field is named an Enhanced Airborne Flight Recorder (EAFR), and laws require two items to be situated within the plane—one on the entrance and one on the aft, or rear part—for redundancy, in case of unit is considerably broken or is rarely recovered. The primary EAFR had been recovered on June 13 from a constructing rooftop on the crash website in Ahmedabad, whereas the second was recovered on June 16 from the plane particles.

“Commonplace Working Procedures had been issued for his or her safe dealing with, storage, and transportation. The units had been saved underneath 24×7 police safety and CCTV surveillance in Ahmedabad. Subsequently, the black containers had been introduced from Ahmedabad to Delhi by IAF (Indian Air Pressure) plane with full safety on 24 June, 2025. The entrance black field arrived at AAIB Lab, Delhi with the DG, AAIB at 1400 hrs on 24 June, 2025. The rear black field was introduced by a second AAIB crew and reached AAIB Lab, Delhi at 1715 hrs on 24 June, 2025,” MoCA stated in its official launch.
The brand new and superior AAIB lab, constructed by assist of government-owned Hindustan Aeronautics Ltd (HAL) and inaugurated in April, has enhanced the company’s means to restore broken black containers, retrieve information, and conduct thorough analyses of accidents with excessive accuracy. Earlier, a black field lab underneath the aviation security regulator Directorate Normal of Civil Aviation (DGCA) was being utilized by the AAIB, however the facility was previous and lacked just a few key capabilities wanted for thorough and correct information retrieval and evaluation, stated a supply. That was one of many the reason why plenty of black containers from plane concerned in severe accidents had been despatched to abroad labs.
The aim of the FDR is to file flight information on quite a few parameters of plane operations, whereas the CVR information the flight crew’s voices, in addition to different sounds contained in the cockpit, together with engine noise, stall warnings, touchdown gear extension and retraction, and different clicks and pops. Communications with air visitors management, automated radio climate briefings, and dialog between the pilots and floor or cabin crew are additionally recorded.
With the info retrieved from the FDR, investigators can generate a pc animated video reconstruction of the flight. The investigators can then visualise the plane’s perspective, instrument readings, energy settings, and different traits of the flight. This animation permits the investigating crew to visualise the final moments of the flight earlier than the accident.

“They (FDR and CVR) can present data that could be troublesome or inconceivable to acquire by different means. When used along with different data gained within the investigation, the recorders are taking part in an ever-increasing position in figuring out the Possible Reason behind an plane accident,” the NTSB says on its web site.
By regulation, plane should monitor a minimum of eighty-eight essential parameters resembling time, altitude, airspeed, heading, and plane perspective. Some FDRs can file the standing of greater than 1,000 different in-flight traits that may assist within the investigation. The objects monitored will be something from flap place to auto-pilot mode and even smoke alarms, the NTSB states.
