The pilot of an aircraft which crashed in Taipei had switched off a working engine after the other lost power, according to Taiwan’s aviation regulator.
Forty-three people died when the TransAsia Airways ATR 72-600, which can fly with one engine, crashed in a river.
In a cockpit recording, the pilot is heard saying: “Wow, pulled back the wrong side throttle.”
The left wing collided with a taxi driving on an elevated expressway.
“The left wing continued to hit the fence of the expressway as well as a light pole, before it crashed into Keelung River,” the report said.
It does not assign blame for the crash which occurred shortly after take-off from Taipei’s Songshan airport in February.
The data report is part of an investigation by the country’s Aviation Safety Council.
