2014-06-24 Asiana Flight 214 – NTSB identifies probable cause
Asiana 214 Crew Errors Caused Accident, Rules NTSB
The NTSB determined that the flight crew mismanaged the initial approach and that the airplane was well above the desired glidepath as it neared the runway. In response to the excessive altitude, the captain selected an inappropriate autopilot mode and took other actions that, unbeknownst to him, resulted in the autothrottle no longer controlling airspeed.
As the airplane descended below the desired glidepath, the crew did not notice the decreasing airspeed nor did they respond to the unstable approach. The flight crew began a go-around maneuver when the airplane was below 100 feet, but it was too late and the airplane struck the seawall.
