Air India crash probe focuses on actions of plane's captain
A preliminary report into the crash released by India's Aircraft Accident Investigation Bureau (AAIB) on Saturday said one pilot was then heard on the cockpit voice recorder asking the other why he cut off the fuel and 'the other pilot responded that he did not do so.' Investigators did not identify which remarks were made by Captain Sumeet Sabharwal and which by First Officer Clive Kunder, who had total flying experience of 15,638 hours and 3,403 hours, respectively.
Kunder, who was flying the plane, asked Sabharwal why he moved the fuel switches to the 'cutoff' position seconds after lifting off the runway, the Wall Street Journal reported. The Journal did not say if there was any evidence that Sabharwal did move the switches, beyond the verbal exchange it cited. But it quoted US pilots who have read the Indian authorities' report as saying that Kunder, the pilot actively flying, likely would have had his hands full pulling back on the Dreamliner's controls at that stage of the flight.
India's AAIB, Directorate General of Civil Aviation, Ministry of Civil Aviation, Air India and two unions representing Indian pilots did not immediately respond to Reuters' requests for comment on the Wall Street Journal report. Boeing declined to comment. The AAIB's preliminary report said the fuel switches had switched from run to cutoff a second apart just after takeoff, but it did not say how they were flipped.
Almost immediately after the plane lifted off the ground, closed-circuit TV footage showed a backup energy source called a ram air turbine had deployed, indicating a loss of power from the engines. The London-bound plane began to lose thrust, and after reaching a height of 650 feet, the jet started to sink.
The fuel switches for both engines were turned back to run, and the airplane automatically tried restarting the engines, the report said. But the plane was too low and too slow to be able to recover, aviation safety expert John Nance told Reuters. The plane clipped some trees and a chimney before crashing in a fireball into a building on a nearby medical college campus, the report said, killing 19 people on the ground and 241 of the 242 on board the 787.
In an internal memo on Monday, Air India CEO Campbell Wilson said the preliminary report found no mechanical or maintenance faults and that all required maintenance had been carried out. The AAIB's preliminary report had no safety recommendations for Boeing or engine manufacturer GE.
After the report was released, the US Federal Aviation Administration and Boeing privately issued notifications that the fuel switch locks on Boeing planes are safe, a document seen by Reuters showed and four sources with knowledge of the matter said.
The circumstantial evidence increasingly indicates that a crew member flipped the engine fuel switches, Nance said, given there was 'no other rational explanation' that was consistent with the information released to date.
Nonetheless, investigators 'still have to dig into all the factors' and rule out other possible contributing factors which would take time, he said. Most air crashes are caused by multiple factors, and under international rules, a final report is expected within a year of an accident.
The Air India crash has rekindled debate over adding flight deck cameras, known as cockpit image recorders, on airliners. Nance said investigators likely would have benefited greatly from having video footage of the cockpit during the Air India flight.
Air India has faced additional scrutiny on other fronts after the crash. The European Union Aviation Safety Agency said this month it plans to investigate its budget airline, Air India Express, after Reuters reported the carrier did not follow a directive to change engine parts of an Airbus AIR.PA A320 in a timely manner and falsified records to show compliance.--AFP

‘Miracle' Air India survivor haunted by nightmares and guilt
LONDON, July 20: Vishwash Kumar Ramesh, the only survivor of the devastating Air India Flight AI171 crash, is struggling to cope with the psychological aftermath of the tragedy that claimed 241 lives, including that of his brother. His family says he suffers recurring nightmares in which he relives the moment of impact and sees 'everyone die.' Ramesh, 40, a British citizen seated in 11A during the ill-fated flight, escaped with cuts to his face and minor chest injuries. Despite the physical recovery, he remains deeply tormented, carrying what relatives describe as an overwhelming sense of survivor's guilt. Dubbed the 'miracle man' and 'God's child' by Indian media, Ramesh has become a symbol of hope. However, his recovery has been overshadowed by grief. His cousin Krunal Keshave, 24, from Leicester, shared: 'He sleeps but not properly. When he does, he dreams he's on the flight again—he saw everyone die in front of him.' The crash, which occurred when the Boeing 787 Dreamliner plummeted shortly after takeoff from Ahmedabad and burst into flames upon hitting a residential building, killed 241 of the 242 people on board, including 52 British nationals. Ramesh's brother, Ajay, 35, was among the victims. The brothers had been running a fishing business in Diu, India, returning to the UK during the off-season. Ramesh, still visibly shaken, told The Sun: 'It's a miracle I survived. I'm OK physically, but I feel terrible that I couldn't save Ajay.' The two had tried booking seats together but were forced to sit separately in row 11. 'If we had sat together, maybe we both would've survived,' Ramesh said. 'But I lost my brother right in front of my eyes. I keep thinking—why couldn't I save him?' Ramesh was seated near an emergency exit and managed to crawl through a gap in the wrecked fuselage. He even tried to re-enter the burning wreckage to save Ajay. Emergency responder Satinder Singh Sandhu recounted: 'He was disoriented and covered in blood. He kept telling us, 'My brother is in there, burning—I have to save him.'' Ramesh later carried his brother's coffin during the funeral in Gujarat, where he broke down in tears and had to be escorted away. One relative said, 'He feels guilty for being the only one who lived. That's a lot to carry.' Evaluation of the crash has since shifted focus to possible human error in the cockpit. A preliminary investigation suggests that Captain Sumeet Sabharwal, 56, may have inadvertently triggered engine failure by switching off two key fuel-related switches, despite his calm demeanor during the incident. First Officer Clive Kunder, 32, who was piloting the aircraft at the time, reportedly panicked as the engines lost power. According to sources familiar with the U.S. probe, the cockpit voice recorder captured a brief exchange in which one pilot questioned the other's actions regarding the switches, with both denying responsibility. The switches were flipped off a second apart, then reactivated ten seconds later—too late to avert disaster. Air India, in a statement, said it 'stands in solidarity with the families and those affected by the AI171 accident' and pledged full cooperation with the Air Accidents Investigation Branch (AAIB) and other authorities involved in the investigation. As the probe continues, Ramesh remains a living reminder of the human cost of the tragedy—a man burdened not only by survival but by the haunting loss of his brother and the lives of hundreds more.

Fuel Cutoff Mystery: Is the Truth About Air India's Crash Being Covered Up?
MUMBAI, July 18: The captain of Air India Flight 171, which crashed shortly after takeoff in Ahmedabad last month, killing 241 of the 242 people on board, reportedly handed control of the aircraft to his first officer seconds before the disaster, according to information retrieved from the flight's black boxes. Sources familiar with the cockpit voice recordings told Italy's Corriere della Sera that Captain Sumeet Sabharwal told First Officer Clive Kunder, 'The plane is in your hands,' moments before the plane left the runway. While it is not uncommon for a first officer to pilot a flight during takeoff, aviation experts have questioned the timing and circumstances of the handover. Flight data shows the aircraft took off at 1:38pm and remained airborne for just 30 seconds before it lost power and crashed into a residential area, killing 19 people on the ground. The sole survivor on board remains in critical condition. Investigators say the plane's engines lost thrust shortly after takeoff, and that the fuel control switches—critical to maintaining engine power—had been moved from the 'run' position to 'cutoff' within seconds of liftoff. According to India's Aircraft Accident Investigation Bureau (AAIB), both switches were turned off and then switched back on about ten seconds later, but not in time to prevent the crash. The AAIB's preliminary report, released last week, confirmed that no mechanical or maintenance faults were found on the aircraft. However, the cause of the fuel cutoff remains under investigation. The switches are designed with safety locks that require manual lifting to operate, making an accidental flip highly unlikely. Cockpit audio captured in the seconds before the crash suggests rising tension between the two pilots. According to sources briefed on the U.S. assessment of the recordings, First Officer Kunder can be heard repeatedly asking, 'Why did you shut off the engines?' to which the senior pilot vaguely replied, 'I didn't do it.' The exchange, lasting six seconds, has been interpreted by some officials as an indirect admission that the captain may have cut the fuel supply. Flight data further reveals that after the aircraft reached approximately 650 feet, a backup power system—known as the Ram Air Turbine (RAT)—deployed, indicating both engines had lost power. Although the fuel switches were returned to 'run' and the engines attempted to restart, the aircraft lacked the altitude and time to recover. The jet clipped treetops and a chimney before crashing into a nearby medical college, erupting in flames. Aviation experts remain baffled by the switch movement. 'It's absolutely bizarre for the engine cutoff switches to be flipped just after takeoff,' said Terry Tozer, a former airline pilot, speaking to Sky News. 'Unfortunately, the altitude was so low that the engines didn't have time to recover.' The AAIB has yet to identify which pilot flipped the switches, and cockpit audio alone has not definitively clarified the roles each pilot played in the final moments. U.S. officials reviewing the early data believe that as the flying pilot, First Officer Kunder would likely have had both hands on the Dreamliner's controls, suggesting Captain Sabharwal may have been responsible for manipulating the switches. Captain Sabharwal had logged over 15,000 hours of flight time, while Kunder had 3,400. According to colleagues cited in Indian media, Sabharwal had recently taken bereavement leave following his mother's death but had been medically cleared to fly. Some sources have raised questions regarding the mental health history of one of the pilots. Captain Mohan Ranganathan, a prominent Indian aviation safety expert, told The Daily Telegraph that one pilot had previously taken extended medical leave for mental health reasons. However, this has not been confirmed by the authorities, and Air India maintains both pilots were fully certified for duty. India's Civil Aviation Minister, Kinjarapu Ram Mohan Naidu, has urged the public to avoid premature conclusions. 'Let us wait for the final report,' he told reporters. Air India CEO Campbell Wilson echoed that message in an internal memo, stating that while the preliminary report found no mechanical issues, further investigation is required to determine the human factors involved. In response to the crash, Indian aviation authorities have ordered comprehensive checks across Air India's Boeing 787 Dreamliner fleet. The airline operates 33 of the aircraft. The AAIB has not issued any immediate safety recommendations to Boeing or the engine manufacturer, General Electric. The agency criticised elements of the international media for 'selective and unverified reporting,' stating that the investigation remains ongoing and that drawing conclusions at this stage is premature. The final report into the crash is expected within 12 months, in line with international aviation standards.

Air India crash probe focuses on actions of plane's captain
INDIA: A cockpit recording of dialogue between the two pilots of the Air India flight that crashed last month indicates the captain cut the flow of fuel to the plane's engines, the Wall Street Journal reported on Wednesday. The newspaper cited people familiar with US officials' early assessment of evidence uncovered in the investigation into the June 12 crash of a Boeing 787 Dreamliner in Ahmedabad, India, that killed 260 people. A preliminary report into the crash released by India's Aircraft Accident Investigation Bureau (AAIB) on Saturday said one pilot was then heard on the cockpit voice recorder asking the other why he cut off the fuel and 'the other pilot responded that he did not do so.'
