TLDR: The FO was the pilot flying. After gaining hardly 500 feet of altitude, the Captain pulled back the fuel supply switches for both engines, from Run to Cutoff. The CVR transcript is widely available by now. The picture below shows switches in the Cutoff position. It is impossible for these switches to be accidentally toggled, because they require a human with two fingers to grip the switch, pull it up out of the socket, transverse over a detent between the two positions, then drop it back down again. When the FO turned them back on, #1 fired, but took too long to reverse the downspooling fan blades. #2 never reignited. May God have mercy on the 260 murdered souls. -nvp
Air India cockpit recording suggests captain cut fuel to engines before crash, source says
WASHINGTON/SEATTLE, July 17 (Reuters) – A cockpit recording of dialogue between the two pilots of the Air India flight that crashed last month supports the view that the captain cut the flow of fuel to the plane’s engines, said a source briefed on U.S. officials’ early assessment of evidence.
The first officer was at the controls of the Boeing 787 and asked the captain why he moved the fuel switches into a position that starved the engines of fuel and requested that he restore the fuel flow, the source told Reuters on condition of anonymity because the matter remains under investigation.
The U.S. assessment is not contained in a formal document, said the source, who emphasized the cause of the June 12 crash in Ahmedabad, India, that killed 260 people remains under investigation.
There was no cockpit video recording definitively showing which pilot flipped the switches, but the weight of evidence from the conversation points to the captain, according to the early assessment.
The Wall Street Journal first reported similar information on Wednesday about the world’s deadliest aviation accident in a decade.
India’s Aircraft Accident Investigation Bureau (AAIB), which is leading the investigation into the crash, said in a statement on Thursday that “certain sections of the international media are repeatedly attempting to draw conclusions through selective and unverified reporting.” It added the investigation was ongoing and it remained too early to draw definitive conclusions.
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.
