The NTSB is recommending that the FAA convene a special certification design review to investigate how Boeing controls airspeed in the Boeing 777’s automatic flight control system.
The call for a special review, an option the FAA rarely uses, is one of 27 recommendations the Board voted to accept today as part of the final hearing on July 6, 2013, crash of Asiana Airlines Flight 214 in San Francisco.

Three passengers were killed and 187 injured when the 777-200ER struck the sea wall ahead of the runway 28L after a visual, hand-flown approach that resulted in the aircraft flying too slowly with its engines idled. The NTSB issued 15 recommendations to the FAA, four to Asiana Airlines, two to Boeing and six airport rescue and firefighting groups and the airport operators.

In its probable cause finding, the Board laid the blame for the accident squarely on the pilots, who “mismanaged the airplane’s descent,” inadequately monitored aircraft performance and delayed a go-around decision until too late despite being aware that the aircraft was “below acceptable glide path and airspeed tolerances” earlier in the approach.

Also included in the probable cause however was the pilot-flying’s “unintended deactivation” of the 777’s automatic airspeed control, an action that investigators linked in part to his confusion about the operations of the Flight Level Change (FLCH) mode of the automatic flight control system. Mode confusion topped the list of five contributing factors, with investigators finding that “complexities of the autothrottle and autopilot flight director systems that were inadequately described in Boeing’s documentation and Asiana’s pilot training” increased the likelihood of mode error.

As of July 8, 2016, a search for the special review proceeding yielded nothing in a search of faa.gov.
