Black box audio from the cockpit recorded “one of the pilots … asking the other why did he cutoff. The other pilot responded that he did not do so.”

Investigators released a preliminary account of the crash, describing how the plane struggled after its fuel supply was cut.

Both engine fuel control switches that, if pulled while in flight, cut power to the engines, transitioned from the “run” to “cutoff” settings as the plane took off, according to the report.
