Pilot error was involved in the Asiana Airlines crash in San Francisco which killed three Chinese teenagers in July, according to investigators.
Veteran pilot Lee Kang Kuk, who was being trained on the Boeing 777, had inadvertently disabled a speed-control system, causing the plane to crash into a seawall, said Bloomberg.
Reporting on the U.S National Transportatin Safety Board hearing into the accident on July 6, Bloomberg said documents revealed the captain had momentarily adjusted the power without realizing the plane’s computers then assumed he wanted the engines to remain at idle.
The documents also raised questions about the design of auto-throttles on Boeing aircraft and wither related training had been adequate.
The safety board has not concluded what caused the crash, which was the first fatal accident in the US since 2009.
