Air India crash probe focuses on actions of plane's captain, WSJ reports
(Reuters) -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 U.S. officials' early assessment of evidence uncovered in the investigation into the June 12 crash in Ahmedabad, India, that killed 260 people.
The first officer, who was flying the Boeing 787 Dreamliner, asked the more experienced captain why he moved the fuel switches to the "cutoff" position seconds after lifting off the runway, the report said.
The two pilots involved were Captain Sumeet Sabharwal and First Officer Clive Kunder, who had total flying experience of 15,638 hours and 3,403 hours, respectively.
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.
A preliminary report into the crash released by India's Aircraft Accident Investigation Bureau (AAIB) on Saturday 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.
One pilot was then heard on the cockpit voice recorder asking the other why he cut off the fuel. "The other pilot responded that he did not do so," the report said.
Without fuel flowing to the engines, the London-bound plane began to lose thrust. After reaching a height of 650 feet, the plane began 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.
NO SAFETY RECOMMENDATIONS
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 U.S. 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 rationale 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 A320 in a timely manner and falsified records to show compliance.

Book Review: ‘The Hiroshima Men' is a reminder of the horrific human costs of atomic attack
John Hersey was a 32-year-old reporter who returned from Japan with in 1946 with a groundbreaking story that challenged U.S. government's version of its atomic bomb attack on Hiroshima, showing the human consequences were far more horrific and extensive than the American public had been told. Hersey's 30,000-word piece for The New Yorker magazine focused on a few of the thousands of survivors who fell ill, and often died, from the lingering effects of radiation long after the bomb's initial impact killed tens of thousands of Japanese men, women and children. Hersey is among diverse group of men author and historian Iain MacGregor profiles in his new book, 'The Hiroshima Men: The Quest to Build the Atomic Bomb, and the Fateful Decision to Use It.' MacGregor earlier wrote 'Checkpoint Charlie,' an acclaimed history of Cold War Berlin, as well as 'The Lighthouse of Stalingrad: The Hidden Truth at the Heart of the Greatest Battle of World War II.' With the 80th anniversary of the Hiroshima attack approaching next month, 'The Hiroshima Men' is a potent reminder of the extreme human costs that were wrought by the first atomic weapon employed during warfare. By profiling some key players, MacGregor pulls readers into their personal stories with visually enticing description and lively dialogue. One was pilot Paul Tibbetts, Jr., who fell in love with flying at age 12 when he rode in an old biplane that took off from a horse racing track outside Miami. He named the Boeing B-29 Superfortress that he was flying when it dropped the atomic bomb on Aug. 6, 1945, for his mother, Enola Gay. Another profile is of J. Robert Oppenheimer, the brilliant scientific theorist who inspired a team testing the atomic bomb at a secret research laboratory in rural New Mexico. There's also Maj. Gen. Henry 'Hap' Arnold, who led the U.S. Army Air Corps in World War II and understood what could be achieved with the faster long-range B-29 bomber, which could travel farther and fly much higher than the popular B-17 that had been used on Europe. MacGregor also introduces us to Senkichi Awaya, the mayor of Hiroshima, a city founded in the late 1580s by a powerful warlord who built a castle headquarters on the shores of a strategically located bay. There are many more. The most powerful sections of the book come toward the end, when MacGregor describes the ghastly aftermath of the bombing — a gruesome hellscape littered with charred bodies and stunned survivors with skin dangling from their bodies and eyes hanging from the sockets. He then invites readers to reflect on the event's profound costs: 'I hope, looking right across the experience of this terrifying and cataclysmic event, that you, the reader, can judge for yourself whether this journey through the experiences of a city mayor, a bomber pilot, an Army general and an award-winning journalist, who all were intimately connected to Hiroshima, was worth it.' ___ AP book reviews:
