The flight was cleared for the visual approach to RWY 28L, which is confirmed by the crew. #Asiana 214
The data indicate that the throttles were at idle and the airspeed slowed below target approach speed during the approach. #Asiana 214
The throttles were advanced a few seconds prior to impact and the engines appear to respond normally. #Asiana 214
