Stitching together evidences in AI plane crash to be tedious process; probe may take time: Former AAIB DG
As the probe continues into the fatal Air India plane crash in Ahmedabad on June 12, former Director General of Aircraft Accident Investigation Bureau (AAIB) Group Captain Aurobindo Handa (Retd) spoke exclusively to PTI on the investigation process. Handa said going by the visuals of the crash, the aircraft has been very badly damaged by fire and stitching together the evidences would be a tedious process. "In all probability and in fairness, the investigation is likely to be a long drawn process," he told PTI. by Taboola by Taboola Sponsored Links Sponsored Links Promoted Links Promoted Links You May Like Sunteck Sky Park, Mira Road - 2 & 3 BHK @ ₹1.33 Cr* Sunteck Sky Park Learn More Undo Handa is also the former Chairman Accident Investigation Group (AIG) of ICAO -APAC Region. During Handa's stewardship, AAIB had closed over 100 investigations, including the fatal crash of Air India Express plane which happened in August 2020 at Kozhikode, Kerala. Live Events Following is the detailed interview How much time do you envisage that the investigation into the Air India plane crash Ahmedabad would take? Annex 13 of the International Civil Aviation Organization (ICAO) as well as AAIB Rules mandate that any investigation should preferably be completed in less than a year. Our investigators' endeavour to complete an investigation as quickly as possible so that remedial actions are instituted quickly through DGCA to avoid any recurrence. However, going by the visuals of this accident, you would appreciate that this aircraft has been very badly damaged by fire. Therefore, corroborating and stitching together the evidences would be a tedious process. In all probability and in fairness, the investigation is likely to be a long-drawn process. How are the probable causes zeroed in during an aircraft accident investigation? Deep and detailed examination of meaningful evidences is a time-consuming process. After analysing the data from the recorders, the investigators narrow down to the most probable systems and/or sub-systems that could have malfunctioned and/or contributed in a malfunction. Step by step, each of the suspected causes for the accident are examined deeply and the unlikely causes are ruled out which is a rigorous process. Basically, the process is driven by the 'method of elimination'. It is akin to a physician going through pathological reports, X-Ray/MRI or other test reports before coming to a conclusion. What is the main aim of an aircraft crash investigation? As per Annex 13 of ICAO and AAIB Rules 2012 (as amended from time to time), the aim of the investigation is to find out the most probable root cause but not to apportion blame or liability. What are the broad steps involved in an investigation? The ICAO had come out with 'DOC 9756' or the Manual of Accident Investigation. Globally, the investigators follow this manual, which outlines detailed procedures to arrive at the most probable cause of an aircraft accident. In addition, based on 'DOC 9756' and its own experiences, AAIB has prepared a document known as 'Procedure Manual' which contains the investigation process/procedures to be followed in India. What are the priorities for AAIB investigators after reaching the aircraft accident site? Obviously, when any unfortunate aircraft accident happens, the immediate focus of the 'first responders' such as airport staff, security personnel which includes CISF, NDRF and local police is to save lives. AAIB takes charge of the activities as soon as its team arrives at the crash site and starts coordinating with the 'first responders' for the remaining work. After cordoning off the general area, AAIB controls and regulates any movement at the crash site in order to make sure that the evidence is not lost inadvertently or tampered with deliberately. AAIB's priorities are to look for survivors and/or save lives at the crash site, retrieve recorders, sift through the debris for any meaningful examination at a later date, and shift these meaningful debris to a safe and secure place. AAIB investigators get divided into sub-groups and start segregating the debris into sub-groups such as flight recorders, airframe, propulsion, avionics and controls, among other elements. The first and foremost task is the retrieval of recorders i.e. Cockpit Voice Recorder (CVR) and Digital Flight Data Recorder (DFDR). Once the retrieval is affected, the next step is 'milking of raw data' from these recorders. The raw data is then converted into actionable and workable 'engineering parameters'. Then, these engineering parameters are converted into graphs and charts for deriving meaningful and credible interpretation. How strong are India's capabilities in analysing the data during an aircraft accident investigation? India as a sovereign nation is quite well equipped to analyse recorders. AAIB, DGCA (Directorate General of Civil Aviation) and airlines also have their recorder labs in place. In case, there is a need, AAIB can seek help from NAL (National Aerospace Laboratories), Bengaluru, HAL ( Hindustan Aeronautics Ltd ), Korwa, and LCA (Light Combat Aircraft) Project as they have excellent infrastructure and enough domain experts of international repute who can be co-opted to assist the aircraft accident investigations and render advice. Also, if there is an iota of doubt that the milking of raw data from the recorders could result in erosion of data, the chief investigator under the guidance from the DG, AAIB can decide to take the recorders to their Original Equipment Manufacturer (OEM). Aircraft manufacturers do not manufacture recorders and these are outsourced from other companies like Honeywell.

Investigators analyze flight recorders in deadly Dreamliner crash
NEW DELHI, India: Indian investigators are examining the black boxes from a Boeing 787 Dreamliner to determine the cause of a catastrophic crash that killed at least 270 people last week. The flight data and cockpit voice recorders were recovered from the wreckage and are expected to provide crucial details about engine performance, control settings, cockpit conversations, and potential distress signals. The Air India flight, bound for London, crashed into a medical college hostel shortly after takeoff from Ahmedabad. Only one person survived out of 242 on board, while 29 others were killed on the ground—making it one of India's worst aviation disasters in decades. The investigation is being led by India's Aircraft Accident Investigation Bureau (AAIB), with support from U.K. and U.S. authorities, including Boeing officials. Aviation expert and former pilot Amit Singh emphasized that black box data will be central to understanding the crash sequence. The cockpit voice recorder captures conversations and alarms in the cockpit, while the digital flight data recorder logs technical metrics such as engine thrust and control settings. "The data will reveal everything," Singh said, noting that communication with air traffic control and emergency warnings will also be analyzed. India's aviation regulator confirmed that a mayday call was made before the crash. Investigators are now reviewing CCTV footage, interviewing eyewitnesses, and examining the pilots' training history, the aircraft's maintenance records, weight and balance, and any prior technical issues. Former AAIB director Aurobindo Handa explained that the investigation will follow international protocols set out in the UN's "DOC 9756" manual. Given the extensive fire damage to the wreckage, Handa warned that assessing the condition of the black boxes—especially their ability to withstand extreme heat—will be critical to the inquiry. The Indian government has also formed a high-level committee to investigate the cause of the crash and recommend future safety measures. A preliminary report is expected within three months. Meanwhile, Air India's entire fleet of 33 Dreamliners is undergoing additional inspections and maintenance checks. The aircraft involved in the crash was 12 years old. Despite a number of safety concerns across Boeing's product line, this marks the first fatal crash of a 787 Dreamliner since the model began operations 16 years ago. There are around 1,200 Dreamliners currently in service worldwide.

Black boxes from India plane crash under study to ascertain cause of the disaster that killed 270
NEW DELHI (AP) — Investigators in India are studying the black boxes of a Boeing 787 Dreamliner after recovering them from the aircraft wreckage to ascertain the cause of last week's plane crash that left at least 270 people dead. The black boxes will provide cockpit conversations and data related to the plane's engine and control settings to investigators and help them in determining the cause of the crash. The London-bound Air India aircraft, a Boeing 787 Dreamliner, crashed on a medical college hostel soon after taking off from the western city of Ahmedabad. Only one passenger survived the crash, while 241 people on board and 29 on the ground were killed in one of India's worst aviation disaster in decades. Experts from India's Aircraft Accident Investigation Bureau are probing the crash with assistance from the U.K., the U.S. and officials from Boeing. Black box data is crucial Amit Singh, a former pilot and an aviation expert, said the recovery of the flight data and cockpit voice recorders, or black boxes, are crucial to piece together the sequence of events. The cockpit voice recorder records pilots' conversation, emergency alarms and any distress signal made before a crash. The plane's digital flight data recorder stores information related to engine and control settings. Both devices are designed to survive a crash. 'The data will reveal everything,' Singh said, adding that the technical details could be corroborated by the cockpit voice recorder that would help investigators know of any communication between air traffic control and the pilots. India's aviation regulatory body has said the aircraft made a mayday call before the crash. Singh said the investigating authorities will scan CCTV footage of the nearby area and speak with witnesses to get to the root cause of the crash. Additionally, Singh said, the investigators will also study the pilot training records, total load of the aircraft, thrust issues related to the plane's engine, as well as its worthiness in terms of past performances and any previously reported issues. Investigation into the crash could take time Aurobindo Handa, former director general of India's Aircraft Accident Investigation Bureau, said the investigators across the world follow a standard UN-prescribed Manual of Accident Investigation, also called 'DOC 9756,' which outlines detailed procedures to arrive at the most probable cause of a crash. Handa said the investigation into last week's crash would likely be a long process as the aircraft was badly charred. He added that ascertaining the condition of the black boxes recovered from the crash site was vital as the heat generated from the crash could be possibly higher than the bearable threshold of the device. The Indian government has set up a separate, high-level committee to examine the causes leading to the crash and formulate procedures to prevent and handle aircraft emergencies in the future. The committee is expected to file a preliminary report within three months. Authorities have also begun inspecting and carrying out additional maintenance and checks of Air India's entire fleet of Boeing 787 Dreamliners to prevent any future incident. Air India has 33 Dreamliners in its fleet. The plane that crashed was 12 years old. Boeing planes have been plagued by safety issues on other types of aircraft. There are currently around 1,200 of the 787 Dreamliner aircraft worldwide and this was the first deadly crash in 16 years of operation, according to experts.
