Asiana crash pilots knew speed was low, hesitated

WASHINGTON - In the crucial minutes before an Asiana Airlines flight crashed in San Francisco last summer, the pilots voiced concern about the plane's low speed but did nothing to correct it until just before it hit the ground.

A hearing on Wednesday into the July 6 crash that killed three people and injured more than 180, highlighted the pilots'mistaken reliance on the autopilot to maintain their airspeed but also Korean cultural factors that may have played a role and the design of the flight controls.

The pilot flying the plane was "stressed" about hand-flying the plane, according to interviews with National Transportation Safety Board investigators, and hesitant about aborting the landing because he felt the more senior pilot observing him should make that call.

Asiana Airlines Inc Flight 214 came in too slowly and too low, causing the plane's tail to hit a seawall short of the runway. The plane spun 330 degrees as it broke apart and caught fire, strewing wreckage along the runway.

It was the first fatal commercial airplane accident in the United States since February of 2009 and the first fatal accident for Boeing Co's 777 airliner since it entered service in 1995.

There was no indication of mechanical problems with the plane.

The crash has sharpened a debate on whether over-reliance on autopilot systems in modern aircraft has led to degraded human flying skills and increased the risk of accidents.

There is "an issue in aviation" with cockpit automation, NTSB Chairman Deborah Hersman told reporters covering the board's hearing but she added that the airline industry has a robust safety record.

Hersman said the agency has no immediate plans to make recommendations from the hearing, but if it finds a safety issue, it can make recommendations at any time.

The NTSB typically takes 12 to 18 months to complete a major investigation.
