Probably shouldn't speculate, especially given the normal accuracy (or lack of it!) in media reports of aircraft crashes. However, if the reports are correct, it sounds as though the left engine failed and the pilot, vastly experienced apparently, then turned left, into the dead engine, an action that has killed lots of experienced pilots over the years, including a highly experienced RQAC instructor some years ago. I also recall watching the Farnborough air show many years ago and a French test pilot was demonstrating the anti-submarine version of the Breguet Atlantic. He came across with the left engine feathered and commenced a turn to the left, my thought was, wow, he must be an expert pilot, but no, the plane stalled and spun down into a hangar. Also back when I was an apprentice at Edinburgh Airport in Scotland I watched a Piper Apache with a failed left engine bank left past the control tower to check if his gear was down and then spun into the ground, cartwheeling across the mainline from Edinburgh to the North of Scotland. On that occasion the occupants were lucky enough to survive. ( Incidentally, the next day I was given a hacksaw an axe and a box of scanners and sent, with a trailer, to bring the wreckage back!) Right from when we first learn to fly two things are drummed into U.S. 1) In an EFATO, do not attempt to turn back to the runway and 2) In a twin with a failed engine, do not turn into the dead engine and yet, people continue to attempt both of those things with fatal results.
