NTSB: Asiana Airline Approached Runway Below Target Speed

NTSB(SAN FRANCISCO) -- After analyzing Asiana Flight 214’s black boxes, the National Transportation Safety Board has a better idea of what caused the Boeing 777 to crash Saturday, killing two people and injuring 182 others.

The cockpit voice recorder was found to have a 2-hour long, good quality recording, and the data recorder recorded 1,400 parameters of data, capturing the entire flight.

According to Deborah Hersman, chair of the NTSB, the approach to the runway was normal. There was no discussion between the pilots of any aircraft anomalies or concerns with approach. An examination of the data recorder found that the plane was approaching the significantly below the target speed of 137 knots, or a little over 157 miles per hour. When asked how much slower, Hersman would only say that “we're not talking about a few knots.”

Crew members called to increase speed seven seconds prior to impact. The sound of a stick shaker, a device which jostles the controls in the pilot’s hand to indicate a stall is imminent, was heard four seconds prior to impact.

The engines appeared to be responding properly when the pilots attempted to increase speed, but it was already too late.

A call to initiate a go-around and attempt to abort the landing, occurred 1.5 second before impact.

All the systems that were required were operable and weather conditions were clear when the plane crashed. The glide slope operation was not functional, but it is not required by the FAA in good weather conditions.

Hersman said the investigation is ongoing.

Asiana Flight 214 Black Boxes Recovered, Appear Intact

NTSB(WASHINGTON) -- The black boxes from Asiana Flight 214 which crash landed at San Francisco International Airport Saturday have been recovered and sent to the National Transportation Safety Board’s Washington headquarters.

The flight data recorder and cockpit voice recorder, more commonly known as black boxes, were found in good condition and may yield critical information that may help determine why the Boeing 777 crashed, killing two 16-year-old Chinese students and wounding almost 200 others.

The recorders arrived at the NTSB lab at 9 a.m. Sunday morning.

“We hope that there is good data, good information on those,” said NTSB Chairwoman Deborah Hersman.

Meanwhile, investigators at the airport continue to comb through the burned out remains of the plane looking for clues. “We have teams that will be looking at aircraft operations and human performance, survival factors and we'll be looking at the aircraft,” Hersman said. “We'll be looking at power plans, systems and structures.”
